Abstract
OBJECTIVE To develop a sensitive and fast detection method via ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) to assess the concentration of ajuforrestin A, ajuforrestin B, ajugamacrin and 8-O-Acetylharpagide primarily derived from Ajuga plants in mice blood and their pharmacokinetics. METHODS Single protein precipitation with high-proportioned acetonitrile is chosen for sample clean-up. The UPLC HSS T3 (2.1 mm × 100 mm, 1.8 µm) column with a mobile phase in gradient elution mode at the flow rate of 0.4 mL/min was used for sample separation. Acetonitrile was selected as the organic phase solution and water containing 0.1% formic acid was chosen as the aqueous solution. A tandem mass spectrometer containing an electrospray ionization (ESI) source in the positive ionization mode was used to detect four compounds via multiple reaction monitoring (MRM). RESULTS The calibration curves (5-1000 ng/mL) of four compounds were linear with correlation coefficients > 0.997. The matrix effects, accuracy, precision, and recovery were all within permissible scope. CONCLUSIONS In this approach, the corresponding pharmacokinetic parameters were successfully clarified in mouse for the first time, which provided a theoretical basis for the improvement of the standard of Ajuga plants and the safety of clinical medication. Furthermore, this method may provide the UPLC-MS/MS evidence for the differentiation of the main close relative varieties of genus Ajuga according to these plants contain different mixtures of the four marker compounds.

Abstract
In this review paper, the occurrence in the plant kingdom, the chemophenetic value and the biological activities associated with two specific phenyl-ethanoid glycosides, i.e., leucosceptoside A and leucosceptoside B, were reported. This is the first work ever conducted on such a subject. Analysis of the literature data clearly led to three important conclusions: leucosceptoside A is much more common in plants than leucosceptoside B; leucosceptoside A exerts more biological activities than leucosceptoside B even if nothing can be generally concluded about which one is actually the most potent; neither of these compounds can be used as a chemophenetic marker. These three aspects and more are discussed in more depth in this work.

Abstract
The isomerism of glucaric acids and the complexity of composition of Leonurus. japonicus Houtt. increased the difficulty of the separation of glucaric acids from the herb. In the present study, three glucaric acids were isolated from Leonurus japonicus Houtt. by using high-speed countercurrent chromatography combined with semi-preparative high-performance liquid chromatography. Cation exchange resin chromatography was applied to remove the alkaloids and enrich the glucaric acid fractions. Preliminary separation of glucaric acids extract by high-speed countercurrent chromatography was carried out at 45℃ by using an optimized solvent system of ethyl acetate/n-butanol/formic acid/water (1:1:0.01:2, v/v/v/v) with satisfied stationary phase retention and separation factor. The semi-preparative high-performance liquid chromatography was used for further separation and purification of the target fractions, and three monomeric compounds were obtained with the purities of 90.0%, 91.0%, and 95.3%. Ultraviolet Spectroscopy, Nuclear Magnetic Resonance Spectroscopy and MS were employed to identify their structures, which were assigned as 2-syringyl glucaric acid, 2,4-disyringyl glucaric acid, and 3,4-disyringyl glucaric acid, respectively, and 2,4-disyringyl glucaric acid was reported for the first time.

Abstract
Liver plays a pivotal role in maintaining blood glucose levels through complex processes which involve the disposal, storage, and endogenous production of this carbohydrate. Insulin is the hormone responsible for regulating hepatic glucose production and glucose storage as glycogen, thus abnormalities in its function lead to hyperglycemia in obese or diabetic patients because of higher production rates and lower capacity to store glucose. In this context, two different but complementary therapeutic approaches can be highlighted to avoid the hyperglycemia generated by the hepatic insulin resistance: 1) enhancing insulin function by inhibiting the protein tyrosine phosphatase 1B, one of the main enzymes that disrupt the insulin signal, and 2) direct regulation of key enzymes involved in hepatic glucose production and glycogen synthesis/breakdown. It is recognized that medicinal plants are a valuable source of molecules with special properties and a wide range of scaffolds that can improve hepatic glucose metabolism. Some molecules, especially phenolic compounds and terpenoids, exhibit a powerful inhibitory capacity on protein tyrosine phosphatase 1B and decrease the expression or activity of the key enzymes involved in the gluconeogenic pathway, such as phosphoenolpyruvate carboxykinase or glucose 6-phosphatase. This review shed light on the progress made in the past 7 years in medicinal plants capable of improving hepatic glucose homeostasis through the two proposed approaches. We suggest that Coreopsis tinctoria, Lithocarpus polystachyus, and Panax ginseng can be good candidates for developing herbal medicines or phytomedicines that target inhibition of hepatic glucose output as they can modulate the activity of PTP-1B, the expression of gluconeogenic enzymes, and the glycogen content.

Abstract
The quality parameters of Leonurus sibiricus L. aerial part crude drugs were evaluated. Fifteen crude drugs were collected from various locations throughout Thailand. The transverse section of the stem of L. sibiricus showed quadrangular character highlighted the ribs with angular collenchyma. The epidermis was uniseriate with abundant glandular trichomes distribution. Prismatic calcium oxalate prisms were found in the stem medullary parenchyma.The histological character of crude drug powder showed bordered pitted vessel, fragment of fiber, glandular trichome, prism crystal, spiral vessel, starch granule, and stomata. The loss on drying, total ash, acid-insoluble ash, and moisture contents should be not more than 8.18, 15.28, 4.04, and 8.91 g/100 g dry weight, whereas ethanol and water-soluble extractive values should be not less than 7.67, and 17.21 g/100 g of dry weight, respectively. Leonurine in the crude drugs were analyzed by capillary electrophoresis (CE) with photodiode array detector. The ethanolic extraction performed by Soxhlet apparatus yielded 18.86 ± 4.09 g/100 g dry weight. The electropherogram detected at 277 nm showed the migration time of leonurine at 6.2 min. The developed CE was found to be valid for leonurine quantification in L. sibiricus ethanolic extract. The contents of leonurine in 15 crude drugs ranged from 0.79 to 4.23 mg/g with the average of 2.38 ± 1.10 mg/g dry weight. This study established the pharmacognostic specification of L. sibiricus crude drug in Thailand with special reference to a bioactive compound, leonurine. CE was beneficial technique for the analysis of leonurine in L. sibiricus aerial parts.

Abstract
Hemp nettle (Galeopsis bifida Boenn.) is a synanthropic species of the Lamiaceae family that is widely distributed across Europe, Asia, and Siberia. Galeopsis bifida is deeply embedded in the ethnomedical tradition of Asian healers; however, this plant is still poorly characterized, both chemically and pharmacologically. To study Siberian populations of G. bifida, we used high-performance liquid chromatography with photodiode array and electrospray triple quadrupole mass detection for metabolic profiling. Ninety compounds were identified, including iridoid glycosides, phenylethanoid glycosides, hydroxycinnamates, and flavone glycosides, most of which were identified in G. bifida for the first time, while some phenolics were found to have potential chemotaxonomic significance in the Lamiaceae family and Galeopsis genus. An unequal quantitative distribution of the selected metabolites was observed within separate organs of the G. bifida plant, characterized by high accumulation of most compounds within the aerial part of the plant (leaves, flowers). Analysis of the content of specific chosen compounds within the leaves of different populations of G. bifida from Eastern Siberia revealed the existence of two chemical types based on metabolic specifics: the southern type accumulates flavone glucuronides, while the northern type tends to accumulate high levels of phenylpropanoids and acylated flavone glucosides. The first study of the bioactivity of G. bifida extract demonstrated that the herb has low toxicity in acute experiments and expresses antioxidant potential against free radicals in the form of DPPH˙, ABTS˙+, and superoxide radical, as well as high ferric reducing antioxidant power, oxygen radical absorbance capacity, and protective action in the carotene bleaching assay. In general, our results suggest the herb of G. bifida as a new, prospective synanthropic plant for medical application.

Abstract
Diabetes mellitus is one of the major health problems in the world, the incidence and associated mortality are increasing. Inadequate regulation of the blood sugar imposes serious consequences for health. Conventional antidiabetic drugs are effective, however, also with unavoidable side effects. On the other hand, medicinal plants may act as an alternative source of antidiabetic agents. Examples of medicinal plants with antidiabetic potential are described, with focuses on preclinical and clinical studies. The beneficial potential of each plant matrix is given by the combined and concerted action of their profile of biologically active compounds.

Components with PTP1b Inhibitory Action and Probable Anti-Diabetic Properties. Curr Top Med Chem 2019; 19:383-392. [DOI: 10.2174/1568026619666190219104430] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2018] [Revised: 02/09/2019] [Accepted: 02/11/2019] [Indexed: 12/13/2022]
Abstract
Background:
The main characteristic of Diabetes type II is the impaired activation of intracellular
mechanisms triggered by the action of insulin. PTP1b is a Protein Tyrosine Phosphatase that
dephosphorylates insulin receptor causing its desensitization. Since inhibition of PTP1b may prolong
insulin receptor activity, PTP1b has become a drug target for the treatment of Diabetes II. Although a
number of inhibitors have been synthesized during the last decades, the research still continues for the
development of more effective and selective compounds. Moreover, several constituents of plants and
edible algae with PTP1b inhibitory action have been found, adding this extra activity at the pallet of
properties of the specific natural products.
Objective:
Sideritis L. (Lamiaceae) is a herbal plant growing around the Mediterranean sea which is included
in the Mediterranean diet for centuries. The present study is the continuation of a previous work
where the antioxidant and anti-inflammatory activities of the components of Sideritis L. were evaluated
and aimed to investigate the potential of some sideritis’s components to act as PTP1b inhibitors, thus
exhibiting the beneficial effect in the treatment of diabetes II.
Methods:
Docking analysis was done to predict PTP1b inhibitory action. Human recombinant PTP1b
enzyme was used for the evaluation of the PTP1b inhibitory action, while inhibition of the human LAR
and human T-cell PTP was tested for the estimation of the selectivity of the compounds.
Conclusion:
Docking analysis effectively predicted inhibition and mode of inhibitory action. According
to the experimental results, four of the components exhibited PTP1b inhibitory action. The most active
ones were acetoside, which acted as a competitive inhibitor, with an IC50 of 4 µM and lavandufolioside,
which acted as an uncompetitive inhibitor, with an IC50 of 9.3 µM. All four compounds exhibited increased
selectivity against PTP1b.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Leonurus sibiricus L. (Lamiaceae), popularly known as motherwort, or "erva-de-macaé" or "rubim" in Brazil, is a plant used for the treatment of inflammatory conditions, but few studies have evaluated this anti-inflammatory activity or other activities that may be relevant. AIM OF THE STUDY This study was undertaken to investigate the antioxidant, antinociceptive and topical anti-inflammatory effects of the ethanol extract of L. sibiricus (EELs). MATERIALS AND METHODS Chromatographic analysis, determination of total phenolic and flavonoid contents and in vitro antioxidant assays were performed, while the formalin test and ear inflammation induced by 12-0-tetradecanoylphorbol-13-acetate (TPA) were performed in mice. RESULTS We observed that total phenolic and flavonoids content in EELs were respectively 60.1mg of gallic acid equivalent/g of extract and 15.4mg of catechin equivalent/g of extract. Chlorogenic, caffeic, p-coumaric and ferulic acids, as well as quercetin were identified in EELs. This extract also led to the consumption of the radicals 2,2-diphenyl-1-picrylhydrazyl, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) and nitric oxide, increased the ferric reducing/antioxidant power (FRAP) and inhibited the spontaneous or FeSO4-induced in vitro lipid peroxidation. In the formalin test, oral pretreatment with EELs (400mg/kg) reduced (p<0.001) the licking/biting time in the second phase, but not in the first phase. In the ear inflammation induced by TPA, the concomitant topical administration of EELs (0.3-3mg/ear) significantly reduced the edema, myeloperoxidase activity, levels of tumoral necrosis factor-α and interleukin-1β and lipoperoxidation, as well as increased FRAP in ear tissue when compared to vehicle-treated ears. CONCLUSIONS These results indicate that EELs has antioxidant, antinociceptive and topical anti-inflammatory activities, supporting the use of this plant in folk medicine.

Abstract
BACKGROUND The phytochemical analysis of Stachys alopecuros subsp. divulsa, an endemic Italian species, has been recently reported and has showed the presence of 8-O-acetylharpagide (2), harpagide (3), allobetonicoside (4), and 4¢-O-galactopyranosyl-teuhircoside (5). In this paper, an in deep study of its glycosidic fraction with the aim to widen the knowledge on its secondary metabolites content is reported. MATERIALS AND METHODS Chromatographic techniques were used for the isolation of constituents while spectroscopic and spectrometric techniques were applied for the structures elucidation. RESULTS Besides the known constituents, all of them reconfirmed, ajugoside (1), reptoside (6) and 6-O-acetyl-ajugol (7) were also identified among the iridoids while the phenolic components resulted to be chlorogenic acid (8), b-arbutin (9), verbascoside (10), and stachysoside A (11), instead. CONCLUSION The iridoid pattern of S. alopecuros subsp. divulsa has been expanded with the identification of not previously reported compounds as well as for the phenolic fraction. Except for the reconfirmed verbascoside (10), the other phenolic compounds were recognized for the first time in the studied species. The complete NMR assignment of compound (1) by means of bidimensional techniques is reported, and both the chemotaxonomic and pharmacological relevance of the isolated compounds is largely discussed.
