Abstract
Agastache rugosa contains phenolic compounds and flavonoids, and has been extensively used as a traditional herbal medicine. The major components in Agastache rugosa extract (ARE) are rosmarinic acid, tilianin, and acacetin, for which several analytical techniques have been reported. However, these substances have yet to be simultaneously quantified in human plasma. In this study, we aimed to simultaneously determine the three active components of ARE in human plasma by developing a reliable quantitative analytical method using ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). Chromatographic separation of the plasma samples was achieved using an ACQUITY UPLC® BEH C18 column with a gradient mobile phase of water and acetonitrile containing 0.1 % formic acid. Mass spectrometric detection was performed using a triple quadrupole tandem mass spectrometer in negative electrospray ionization (ESI-) and multiple reaction monitoring (MRM) modes. The developed quantitative method was validated for the three active components. All three analytes exhibited a linear response over the ranges of 0.5-50 ng/mL for rosmarinic acid, 0.1-20 ng/mL for acacetin, and 0.5-20 ng/mL for tilianin with a weighting factor of 1/x (where x is the concentration). At three quality control (QC) concentration levels (low, medium, and high), including the lower limit of quantitation (LLOQ), acceptable accuracy (±15 %) was achieved in the intra- and interday validations. The concentration of rosmarinic acid was highest in plasma. Tilianin and acacetin appeared and were eliminated earlier in the plasma than rosmarinic acid. This study provides a successfully validated method that can be used in further clinical applications of Agastache rugosa extracts.

Abstract
The objective of this study was to determine the optimal dose of silver nitrate (AgNO3) for plant growth and to increase the main bioactive compounds in A. rugosa cultivated in a hydroponic system. The application of soaked diniconazole (120 μmol mol-1) to all plants at 7 days after transplanting (DAT) for dwarfing plant height, optimizing cultivation space in the plant factory. Subsequently, plants were soaked with 50, 100, 200, and 400 μmol mol-1 AgNO3 for 10 min at 25 DAT and harvested at 39 DAT. The results indicated that 200 and 400 μmol mol-1 treatments tended to severely decrease plant growth parameters compared to treatments with lower concentrations. The net photosynthetic rate was significantly reduced by the 200 and 400 μmol mol-1 treatments compared to treatments with other concentrations. The 400 μmol mol-1 treatment led to the lowest concentrations of chlorophyll a, chlorophyll a/b, total carotenoid, chlorophyll b, and the total chlorophyll. However, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity was considerably increased in 50, 100, 200, and 400 μmol mol-1 compared to that of the control plants. A higher rosmarinic acid (RA) concentration in the whole plant was noticed with the 400 μmol mol-1 treatment compared with that of the untreated plants. The 100 μmol mol-1 treatment exhibited the highest concentration and content of tilianin in the whole plant. Concentration of acacetin 1 significantly increased in the whole plant with 100 and 200 μmol mol-1 treatments compared with that of the untreated plants. Concentrations of acacetin 2 and 3 in the whole plant were the highest with 100 and 200 μmol mol-1 treatments, respectively. The results demonstrated that 100 μmol mol-1 treatments can be used to increase bioactive compounds without severely limiting the plant growth and reducing chlorophyll concentrations of A. rugosa. Implementing this optimal dose can enable growers and researchers to cultivate A. rugosa more efficiently, enhancing bioactive compound content and overall plant performance, thus harnessing the potential health benefits of this valuable plant species.

Abstract
BACKGROUND The huge global burden of atherosclerotic cardiovascular diseases (CVDs) represents an urgent unmet need for the development of novel therapeutics. Dracocephalum moldavica L. has been used as a traditional Uygur medicine to treat various CVDs for centuries. Tilianin is a major flavonoid component of D. moldavica L. and has potential for preventing atherosclerosis. However, the molecular mechanisms that tilianin attenuate atherosclerosis are far from fully understood. PURPOSES The purpose of this study is to investigate the efficiency and underlying mechanisms of tilianin in controlling lipid profile and preventing atherogenesis. METHODS The lipid-lowering effect of tilianin was evaluated in C57BL/6 and ApoE-/- mice by systematically determining serum biochemical parameters. The effects of tilianin on the atherosclerotic lesion were observed in aortic roots and whole aortas of ApoE-/- mice with oil red O staining. Caecal content from ApoE-/- mice were collected for 16S rRNA gene sequence analysis to assess the structure of the gut microbiota. The inhibition of hepatosteatosis was verified by histological examination, and a liver transcriptome analysis was performed to elucidate the tilianin-induced hepatic transcriptional alterations. Effects of tilianin on the expression and function of LDLR were examined in HepG2 cells and ApoE-/- mice. Further mechanisms underlying the efficacy of tilianin were investigated in HepG2 cells. RESULTS Tilianin treatment improved lipid profiles in C57BL/6 and dyslipidemic ApoE-/- mice, especially reducing the serum LDL-cholesterol (LDL-C) level. Significant reductions of atherosclerotic lesion area and hepatosteatosis were observed in tilianin-treated ApoE-/- mice. The altered gut microbial composition in tilianin groups was associated with lipid metabolism and atherosclerosis. The liver transcriptome revealed that tilianin regulated the transcription of lipid metabolism-related genes. Then both in vitro and in vivo analyses revealed the potent effect of tilianin to enhance hepatic LDLR expression and its mediated LDL-C uptake. Further studies confirmed a critical role of SREBP2 in hepatic LDLR up-regulation by tilianin via increasing precursor and thus mature nuclear SREBP2 level. CONCLUSION This study demonstrated the lipid-lowering effect of tilianin through SREBP2-mediated transcriptional activation of LDLR. Our findings reveal a novel anti-atherosclerotic mechanism of tilianin and underlie its potential clinical use in modulating CVDs with good availability and affordability.

Abstract
Ovarian cancer is one of the deadliest gynecologic malignancies and is the seventh leading cause of mortalities and morbidities globally. Although there are various therapeutic strategies, a major challenge for scientific community is to come up with effective strategy to treat ovarian cancer. Tilianin, a polyphenol flavonoid is well known for its extensive biological actions like cardioprotective, neuroprotective, anti-oxidant, anti-inflammatory, anti-diabetic and anti-tumor properties. The current study is designed to investigate the anti-cancer action of Tilianin in ovarian cancer (PA-1) cells. The findings of this study revealed that Tilianin treatment results in significant and concentration dependent decrease in cell viability. The growth inhibiting action of Tilianin is associated with apoptosis which was confirmed by DAPI and AO/EtBr staining. The Tilianin-triggered apoptosis in PA-1 cells was correlated with elevated generation of ROS, loss of mitochondrial membrane potential, alterations in pro-apoptotic (upregulated mRNA expression of Bax) and anti-apoptotic (downregulated mRNA expression of Bcl2) factors and activation of caspase-8, −9 and −3. Cell cycle analysis revealed that Tilianin treatment prevented G1/S transition through reduced mRNA expression of cyclin D1. Additionally, the findings of this study also showed Tilianin inhibited JAK2/STAT3 signaling (downregulated expression of pJAK2, JAK2, pSTAT3, and STAT3) with no change in mRNA expression level of ERK indicating its non-involvement in the apoptotic and/or growth inhibition of ovarian cancer cells. In conclusion, the findings of this exploration provided clear evidence of anti-cancer effects of Tilianin in PA-1 cells through its anti-proliferative action, ability to induce apoptosis both through extrinsic and intrinsic pathways, cell cycle (G1/S) arrest and JAK2/STAT3 signaling inhibition.

Abstract
Diabetic cardiomyopathy (DCM) is a chronic multifactorial complication of type-2 diabetes mellitus, leading to heart failure. A combination of multifaceted therapeutics for the management of DCM is needed. Here, we investigated the combined effect of syringin and tilianin on DCM by evaluating cardiac function, inflammation, oxidative stress, apoptosis and mitochondrial function, and explored the contribution of TLR4/NF-κB/NLRP3 and PGC1α/SIRT3 pathways in diabetic rats and hyperglycemic-H9c2 cells. Syringin and tilianin (50 and 60 mg/kg, i.p, respectively) were administered for eight weeks, individually or in combination, to healthy and type-2 diabetic Sprague-Dawley rats. Myocardial function was recorded using a carotid catheter, mitochondrial and histopathological changes were evaluated by fluorometric and staining methods, cardiac markers and signaling pathways' proteins expression were measured through ELISA and immunoblotting. In comparison to individual treatments, combination of syringin and tilianin effectively exerted antidiabetic effects and improved cardiac function and DCM markers, reduced NLRP3/IL-6/IL-1β/TNF-α expression, and suppressed diabetes/hyperglycemia‑induced oxidative stress in rats' heart and H9c2 cells, as demonstrated by decreased 8-isoprostane, and increased superoxide dismutase-2 levels. Mitochondrial membrane depolarization and ROS production were inhibited, and caspase-3 and Bax/Bcl2 expression downregulated by combination therapy. Combined treatment markedly inhibited up-regulation of TLR4, MyD88 and NF-κB in diabetic rats. Finally, inhibition of PGC1α/SIRT3 pathway by 3-TYP in hyperglycemic H9c2-cells reversed the beneficial effects of combination therapy on cardiomyocytes injury and NF-κB/NLRP3/IL-1β expression, without affecting TLR4/MyD88 expression. Syringin plus tilianin synergistically inhibited the diabetes-induced cardiac functional, biochemical and histopathological changes in DCM. Crosstalk between TLR4/NF-κB/NLRP3 and PGC1α/SIRT3/mitochondrial pathways contributed to this protection.

Abstract
BACKGROUND Acacetin 7-O-β-D-glucoside (tilianin) is a major constituent of Agastache rugosa, a traditional medicine that has long been used for the treatment of gastrointestinal disorders. Tilianin has a wide variety of pharmacological properties such as cardioprotective, neuroprotective, and anti-atherogenic activities. We recently discovered that tilianin has the ability to suppress MUC5AC expression in vitro. In addition, we have established an in vivo model of allergic asthma using house dust mite (HDM) that can be applied to tilianin. PURPOSE We investigated the effects of tilianin on airway inflammation in a HDM-induced asthma mouse model and associated mechanisms. METHODS Tilianin was treated in splenocytes cultured in Th0 condition and HDM-stimulated bone marrow-derived dendritic cells (BMDCs), and their mRNA expression and cytokines production were determined by quantitative real-time PCR and ELISA. To evaluate the effects of tilianin in an allergic asthma model, mice were sensitized and challenged with HDM. Tilianin was administered prior to challenge by oral gavage and airway hyper-reactivity (AHR) to methacholine, inflammatory cell infiltration, cytokine levels, and airway remodeling were assessed. RESULTS Tilianin inhibited the production of Th2-related cytokines in splenocytes, which play pivotal roles in allergic airway inflammation. When treated in HDM-stimulated BMDCs, tilianin decreased Th2-skewing cytokine IL-33 and transcription factor IRF4. On the contrary, tilianin increased Th1-skewing regulators, IL-12 and IRF1. In an HDM-induced asthmatic mouse model, tilianin attenuated AHR and airway inflammation. Tilianin suppressed the expression of Th2-related cytokines, IL-13 and IL-33 in lung tissues. As seen in HDM-stimulated BMDCs, tilianin also downregulated the expression of the transcription factor IRF4 but not IRF1. CONCLUSION Taken together, these results suggest that tilianin attenuates HDM-induced allergic airway inflammation by inhibiting Th2-mediated inflammation through the selective inhibition of the IRF4-IL-33 axis in dendritic cells.

Abstract
The present study was undertaken to assess the protective effects of Tilianin (TN) on type-2 diabetes-induced renal dysfunction in experimental rats. Diabetes was induced by injecting Nicotinamide (110 mg/kg) and streptozotocin (55 mg/kg) by i.p. and then the rats were treated with TN (10 and 20 mg/kg) daily by oral gavage for 28 days. TN treatment significantly decreases the BUN, creatinine, 24-hour urinary protein, urea, uric acid, and albumin protein levels. The protein of expression of Nrf2, NQO1, and HO-1 was augmented while the expression of Keap-1 decreased significantly. TN also reduces the oxidative/nitrosative status by lowering MDA content, NO, and MPO levels. TN exerted anti-inflammatory effects by suppressing TLR4/NF-κB/MAPK signaling cascades and inhibiting MyD88, TRAF6, IκBα, p38MAPK, JNK, and ERK2 in the diabetic rats. Histopathological findings supported the biochemical and molecular results. The results showed that TN modulated Nrf2-Keap1 and TLR4/MAPK/NF-κB signaling pathways and provided significant protection against diabetes-induced renal dysfunction.

Abstract
Tilianin (TIL) may prevent and treat myocardial ischemia reperfusion injuries. However, its oral administration is hampered by its low bioavailability. The present study aimed to formulate lipid-polymer hybrid nanoparticles (LPHNs) as carriers for the sustained release and oral bioavailability enhancement of TIL in vitro and in vivo. A nanodrug delivery system of TIL-loaded LPHNs (TIL-LPHNs) was constructed. TIL-LPHNs were prepared via a self-assembly method, and their particle size, polymer dispersity index (PDI), zeta potential, encapsulation efficiency (EE) and morphology were investigated. In addition, pharmacokinetic studies were performed in vivo. The TIL-LPHN formulation produced a spherical, homogeneous, smooth surface and multi-lamellar structured nanoparticles. The particle size and distribution profile of TIL-LPHNs had a mean particle diameter of 54.6 ± 5.3 nm and PDI of 0.112 ± 0.017. The zeta potential was -33.4 ± 4.7 mV. The EE of TIL-LPHNs was 86.6 ± 3.6%, which was determined with the dialysis method. The TIL-LPHNs significantly enhanced the oral bioavailability of TIL with a 3.7-fold increase in the area under the concentration-time curve in comparison with the TIL solution. These findings support the potential use of LPHNs in improving the stability and bioavailability of TIL via oral administration.

Abstract
Mitochondrial energy metabolism and oxidative stress play a crucial role in ameliorating myocardial ischemia/reperfusion injury (MIRI). Tilianin has been reported to have a significant protection for mitochondrion in MIRI. However, the underlying mechanisms remain unknown. This study investigated whether Tilianin regulates mitochondrial energy metabolism and oxidative stress in MIRI via AMPK/SIRT1/PGC-1 alpha signaling pathway. The MIRI model was established by 30 min of coronary occlusion followed by 2 h of reperfusion in rats. The results revealed that Tilianin significantly reduced myocardial infarction, improved the pathological morphology of myocardium, markedly increased the contents of ATP and NAD+, decreased ADP and AMP contents and the ratio of AMP/ATP, reduced the level of ROS and MDA, enhanced SOD activity, evidently increased the levels of AMPK, SIRT1 and PGC-1 alpha mRNA, up-regulated the expressions of AMPK, pAMPK, SIRT1, PGC-1alpha, NRF1, TFAM and FOXO1 proteins. However, these effects were respectively abolished by Compound C (a specific AMPK inhibitor) and EX-527 (a specific SIRT1 inhibitor). Taken together, this study found that Tilianin could attenuate MIRI by improving mitochondrial energy metabolism and reducing oxidative stress via AMPK/SIRT1/PGC-1 alpha signaling pathway.

Abstract
Agastache mexicana has gained importance during the last decade as a natural source of bioactive compounds, mainly due to the antidiabetic, antihyperlipidemic, and vasorelaxant effects derived from its flavonoids, particularly tilianin. The goal of this work was to evaluate the production of tilianin during the in-vitro process of morphogenesis leading to plant regeneration and to investigate the vasorelaxant activity of its methanolic extracts. The cultures were established from nodal segments and leaf explants, inoculated on Murashige and Skoog (MS) media supplemented with various concentrations of benzyl aminopurine (BAP) alone or in combination with 2,4-Dichlorophenoxyacetic acid (2,4-D). Callus inductions were obtained in all treatments from both types of explants, but the presence of auxin was essential. Maximal shoot multiplication and elongation was achieved with 0.1 mg/l 2,4-D and 1.0 mg/l BAP from nodal- segment explants. Shoots were rooted in 75% MS medium and the plantlets were transferred to a greenhouse with 33% average survival. Analysis of tilianin production in methanolic extracts from calli (0.15-2.01 ± 0.06 mg/g dry weight), shoots (4.45 ± 0.01 mg/g DW), and whole plants (9.77 ± 0.02 mg/g DW) derived from in-vitro cultured nodal segments reveals that tilianin accumulation is associated with high cell differentiation and morphogenetic response to the plant-growth regulators. All of the extracts showed strong vasorelaxant activity, as compared to those of wild plant extracts. These results indicate that plant-tissue cultures of A. mexicana possess vast potential as a source of tilianin and other bioactive compounds.

Abstract
BACKGROUND Tilianin has been demonstrated to exert protective effects on the heart against ischemia-reperfusion (I/R) injury, yet whether it is beneficial to the mitochondria during myocardial I/R is unclear. METHODS In this study, we demonstrated that pretreatment with Tilianin dose-dependently raised the levels of ATP of the myocardium, and protected the microstructures and functions of mitochondria in rats. Furthermore, the cytoprotective effect of Tilianin has been confirmed in vivo and in the H9c2 cardiomyoblast cell line with enhancing activities of the mitochondria, controlling the levels of Ca2+ and reactive oxygen species (ROS), and inhibiting the expression of caspase-3 and AIF in cytoplasm. CONCLUSIONS In conclusion, the study suggests that Tilianin may be of clinical value for the protective effects of cardiomyocytes and mitochondria by inhibiting myocardium energy metabolism and apoptosis during myocardial ischemia-reperfusion injury (MIRI).

Abstract
Background In the Chinese traditional medicine, plant of Agastache rugosa (Fisch. & C.A. Mey.) Kuntze (A. rugosa) has been used to treat nausea, vomiting and dispel damp. However, currently, few reports about the chemical constituents, especially the non-volatile components of A. rugosa are available. Methods Through separation with various column chromatographies to elucidate the chemical constituents of A. rugosa, the biological activities of the major constituents were investigated. The extracts and main constituents of A. rugosa were evaluated for their anticoagulant effects by assaying the activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT) and fibrinogen (FIB) in vitro. Results Seven known compounds (namely compounds 1–7) were isolated from the aerial parts of A. rugosa. They were identified as methyl hexadecanoate (1), β-sitosterol (2), acacetin (3), ursolic acid (4), apigenin (5), protocatechuic acid (6) and tilianin (7), respectively. Compounds 1 and 6 were isolated from the genus Agastache for the first time, and compound 4 was obtained from the plants for the first time. The results showed that the extract of A. rugosa had a significant procoagulant activity by shortening the time of PT (P < 0.001) and increasing FIB content (P < 0.001), as compared with Vitamin K1. While its major constituents acacetin and tilianin exhibited significant anticoagulant activities by prolonging the times of PT, APTT, TT and reducing FIB content (P < 0.001), as compared with blank control group. Conclusions The total extract of A. rugosa possessed significant procoagulant activity, while its main components, acacetin and tilianin possessed significant anticoagulant activities. Further investigation should be pursued to find out the bioactivity components responsible for the procoagulant action of the plant.

Abstract
Ionic liquid 1-butyl-3-methylimidazolium bromide-methanol-based ultrasonic-assisted extraction (ILUAE) was used to extract tilianin and acacetin from the aerial parts of Agastache rugose (A. rugose), and simultaneously determined by reversed phase high performance liquid chromatographic (RP-HPLC) method with ultraviolet detection (RP-HPLC-UV). An InertSustain RP-C18 column was used with the mobile phase consisting of methanol and 0.2% acetic acid as gradient elution at the detection wavelength of 332 nm. The flow rate was 0.8 mL/min, and the column temperature was 30 °C. Under the optimized conditions, tilianin and acacetin displayed good linearity in the ranges of 0.0595–4.76 and 0.0585–4.68 μg/mL, respectively, with the average recoveries being 96.93 and 97.88%, respectively. The method of ILUAE was compared with the traditional methods, it exhibited higher efficiency, higher reproducibility and environmental friendly in analyzing the active compounds in traditional Chinese medicines (TCMs).

Abstract
OBJECTIVES To develop a practical method to prepare tilianin by highly selective and efficient hydrolysis of the C-7 rhamnosyl group from linarin. RESULTS Naringinase was utilized to selectively catalyze the formation of tilianin using linarin as the starting material. The reaction conditions, including temperature, pH, metal ions, substrate concentration and enzyme concentration, were optimized. At 60 °C, naringinase showed enhanced α-L-rhamnosidase activity while the β-D-glucosidase activity was abrogated. The addition of Mg(2+), Fe(2+) and Co(2+) was also beneficial for selective biotransformation of linarin to tilianin. Under the optimized conditions (pH 7.0 at 60 °C), linarin could be nearly completely transformed to tilianin with excellent selectivity (>98.9 %), while that of the by-product acacetin was less than 1.1 %. In addition, the structure of target product tilianin was fully characterized by HR-MS and (1)H-NMR. CONCLUSION A highly selective and efficient biotransformation of linarin to tilianin was developed by the proper control of incubation temperature, which enhanced the α-L-rhamnosidase activity of naringinase and blocked its β-D-glucosidase activity.

Abstract
Tilianin is attracting considerable attention because of its antihypertensive, anti-atherogenic and anticonvulsive efficacy. However, tilianin has poor oral bioavailability. Thus, to improve the oral bioavailability of tilianin, composite phospholipid liposomes were adopted in this work as a novel nanoformulation. The aim was to develop and formulate tilianin composite phospholipid liposomes (TCPLs) through ethanol injection and to apply the response surface-central composite design to optimize the tilianin composite phospholipid liposome formulation. The independent variables were the amount of phospholipids (X1), amount of cholesterol (X2) and weight ratio of phospholipid to drug (X3); the depended variables were particle size (Y1) and encapsulation efficiency (EE) (Y2) of TCPLs. Results indicated that the optimum preparation conditions were as follows: phospholipid amount, 500 mg, cholesterol amount, 50mg and phospholipid/drug ratio, 25. These variables were also the major contributing variables for particle size (101.4 ± 6.1 nm), higher EE (90.28% ± 1.36%), zeta potential (-18.3 ± 2.6 mV) and PDI (0.122 ± 0.027). Subsequently, differential scanning calorimetry techniques were used to investigate the molecular interaction in TCPLs, and the in vitro drug release of tilianin and TCPLs was investigated by the second method of dissolution in the Chinese Pharmacopoeia (Edition 2015). Furthermore, pharmacokinetics in Sprague Dawley rats was evaluated using a rat jugular vein intubation tube. Results demonstrated that the Cmax of TCPLs became 5.7 times higher than that of tilianin solution and that the area under the curve of TCPLs became about 4.6-fold higher than that of tilianin solution. Overall, our results suggested that the prepared tilianin composite phospholipid liposome formulations could be used to improve the bioavailability of tilianin after oral administration.

Abstract
OBJECTIVE To determine the depressant-like effects and the possible mechanism of action of tilianin isolated from active methanol extract of Agastache mexicana (A. mexicana). Also, to establish the pharmacophoric requirements of tilianin, as a possible ligand of GABAA/BZD receptor, by the alignment of diazepam, CGS-9896 and diindole, using a previously described pharmacophoric model. METHODS Tilianin (30 to 300 mg/kg, ip. and 300 mg/kg, po.) and methanol crude extract (10 to 300 mg/kg, ip. and 300 mg/kg po.) from A. mexicana were evaluated for potential sedative and anxiolytic-like response drugs by using open-field, hole-board, cylinder of exploration, plus-maze and sodium pentobarbital-induced hypnosis mice methods. RESULTS Methanol extract and tilianin showed anxiolytic-like activity from a dosage of 30 mg/kg, ip. or 300 mg/kg, po. and were less potent than diazepam 0.1 mg/kg, a reference anxiolytic drug used. Moreover, depressant activity of both potentiates sodium pentobarbital (SP)-induced sleeping time. The anxiolytic-like effect of 30 mg/kg ip. observed for the extract and tilianin, by using the plus-maze model, was partially prevented in the presence of flumazenil (a GABAA/BZD antagonist, 5 mg/kg ip.) but not in the presence of WAY 100635 (a selective 5-HT1A receptor antagonist, 0.32 mg/kg, ip.). Pharmacophoric modeling alignments of three agonist of GABAA/BZD allow identify seven chemical features. Tilianin contains six of the seven features previously determined. CONCLUSIONS Results indicate that tilianin is one of the bioactive metabolites in the anxiolytic-like activity of A. mexicana, reinforcing its central nervous system uses, where GABAA/BZD, but not 5-HT1A, receptors are partially involved.

Abstract
Agastache is a small genus of Lamiaceae, comprising 22 species of perennial aromatic medicinal herbs. In this article, we review recent advances in phytochemical, pharmacological, biotechnological and molecular research on Agastache. The phytochemical profile of all Agastache species studied to date is generally similar, consisted of two main metabolic classes-phenylpropanoids and terpenoids. In the relatively variable essential oils, most populations of different Agastache species contain over 50 % of a phenylallyl compound-estragole. Also, other volatile compounds (methyleugenol, pulegone, menthone, isomenthone and spathulenol) were reported in various proportions. Major non-volatile metabolites belong to phenolic compounds, such as caffeic acid derivatives, especially rosmarinic acid as well as several flavones and flavone glycosides like acacetin, tilianin, agastachoside, and a rare dimeric malonyl flavone (agastachin). Two unique lignans-agastenol and agastinol-were also isolated. Terpenoids include triterpenoids of oleanane-type (maslinic acid, oleanolic acid and β-amyrin), ursane-type (ursolic acid, corosolic acid and α-amyrin), and typical plant sterols, as well as abietane-type oxidized diterpenes (e.g., agastaquinone, agastol, and others). The bioactivity of various extracts or individual compounds in vitro and in vivo include antimicrobial, antiviral and anti-mutagenic activity, cytotoxic activity to cancer cell lines, and anti-nociceptive, anti-inflammatory, anti-atherogenic, antioxidant as well as biocidal activity to several foodstuff pests. Biotechnological and molecular studies have focused on in vitro propagation and enhancing the biosynthesis of bioactive metabolites in cell or organ cultures, as well as on the expression of genes involved in phenolic biosynthesis.
