Abstract
Three nor-sesquiterpenes, phellinharts A-C (1-3), isolated from Phellinus hartigii, exhibited unprecedented protoilludane and cerapicane-type structures. The structures of compounds 1-3 were elucidated via spectroscopic analysis, quantum chemical calculations, and X-ray diffraction. Potential biogenic pathways involving demethylation, ring cleavage, and rearrangement were proposed. Compounds 1-3 displayed potent anti-hypertrophic activities with low cytotoxicity (CC50 > 50 μM) in rat cardiomyocytes, underscoring their therapeutic potential.

Abstract
Eleven new acyl-quinic acids (AQAs) 1a-9, and 18 known AQAs 10-27 were isolated from the root bark of Acanthopanax gracilistylus W. W. Smith (Acanthopanacis Cortex). The planar structures of 1a-9 were determined based on their HR-ESIMS, IR, and NMR data. The absolute configurations of 1a-6 were identified by comparing the experimental and the calculated electronic circular dichroism (ECD) spectra. This is the first report of the isolation of AQAs from Acanthopanacis Cortex. Notably, 1a-6 were determined as unusual oxyneolignan-(-)-quinic acids heterodimers, representing a new class of natural products. The inhibitory activities of 1a-27 on neutrophil elastase (NE) and cyclooxygenase-2 (COX-2) were studied in vitro, and the results indicated they possessed significant inhibitory activities on COX-2. Among them, the IC50 values of 1a-9 were 0.63±0.014, 0.75±0.028, 0.15±0.023, 0.63±0.016, 0.30±0.013, 35.63±4.600, 8.70±1.241, 16.51±0.480, 0.69±0.049, 0.39±0.017, and 0.26±0.080 μM, respectively. This study represents the inaugural disclosure of the anti-COX-2 constituents found in Acanthopanacis Cortex, thereby furnishing valuable insights into the exploration of novel COX-2 inhibitors derived from natural reservoirs.

Abstract
Twenty-four monoterpenoids, including three previously undescribed compounds (1-3), were isolated from the root bark of Acanthopanax gracilistylus W. W. Smith (Acanthopanacis Cortex). Their structures were unambiguously established based on spectroscopic analysis (HR-ESIMS, IR, 1D, and 2D NMR), and the absolute configurations of 1-3 were elucidated by comparing their experimental and calculated electronic circular dichroism spectra. In addition, the structure of 8 was confirmed by single-crystal X-ray diffraction. The inhibitory activities of 1-24 against neutrophil elastase, 5-lipoxygenase, and cyclooxygenase-2 (COX-2) were studied in vitro for the first time, and the results showed that compound 24 possessed a significant inhibitory effect on COX-2 with an IC50 value of 1.53 ± 0.10 μΜ. This research first reported the presence of monoterpenoids in Acanthopanacis Cortex, including one monoterpenoid 2 with an unusual 4/5 bicyclic lactone system, and compounds 4 and 5 have never been reported in nature.

Abstract
The previous research results showed that the extracts of ethyl acetate of the rhizome of Ligusticum chuanxiong (Rhizoma chuanxiong) possessed significant antigout effects in model mice. To explore the active ingredients responsible for the effects, phytochemical studies were performed, which led to the isolation of three rare 8', 9-linked neolignans, ligusticumins A-C (1-3), together with two novel phthalide-phenylpropanoid heterodimers, ligusticumalides A-B (4 and 5). It is noteworthy that 4 possesses an unprecedented 7-styryl phthalide skeleton. The structures and absolute configurations of 1-5 were elucidated by one-dimensional (1D) and two-dimensional (2D) NMR spectroscopy and electron-capture detector (ECD) spectroscopic methods. The bioassay results showed that compounds 1, 2, 3, and 5 presented moderate inhibitory activities against xanthine oxidase (XO) and 4 possessed a significant XO inhibitory effect with an IC50 value of 93.88 μM. This is the first time to investigate the anti-XO active ingredients of R. chuanxiong, which provides valuable information for searching for new antigout agents from natural products.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Eleutherococcus nodiflorus (Dunn) S.Y.Hu (Araliaceae), also called Eleutherococcus gracilistylus, Acanthopanax gracilistylus, and Xi-zhu-wu-jia (Wujiapi or Nan Wujiapi) in Chinese, is a widely used traditional Chinese herb with the effects of dispelling pathogenic wind and eliminating dampness, nourishing liver and kidney, diuresis and detumescence, promoting blood circulation for removing blood stasis, and strengthening the bones and tendons according to the theory of Traditional Chinese Medicine (TCM). It has been used as medicine for the treatment of paralysis, arthritis, rheumatism, lameness, body asthenia, fatigue, edema, beriberi, and liver diseases. Meanwhile, E. nodiflorus (EN, thereafter) has ginseng-like activities known as "ginseng-like herb". AIMS OF THE REVIEW This review aims to present comprehensive information for the research progress of EN, including taxonomic position, botany, traditional usages, phytochemistry, pharmaceutical analysis, pharmacology and toxicology. Among them, phytochemical and pharmacological studies are mainly focused. MATERIALS AND METHODS Relevant literature was acquired from scientific databases including Web of Science, PubMed, Google Scholar, Baidu Scholar, SciFinder and Chinese national knowledge infrastructure (CNKI). Monographs and Chinese pharmacopeia were also utilized as references. RESULTS In the past decade, a great number of phytochemical and pharmaceutical analyses, as well as pharmacological studies on EN have been carried out. Several kinds of chemical compositions have been reported, including essential oil, sesquiterpenes, diterpenes, triterpenes, phenylpropanoids, lignans, caffeoyl quinic acids, flavonoids, steroids, fatty acids, ceramides as well as other compounds, among which, diterpenes and triterpenes were considered to be the most active components. The fingerprint chromatography, qualitative and quantitative analysis were used for the methods of quality control of EN. Considerable pharmacological experiments in vitro and in vivo have demonstrated that EN possessed hypoglycemic, anti-inflammatory, anticancer, anti-ageing, anti-fatigue, immunomodulatory, hepatoprotective, antioxidant, anti-AChE, anti-BuChE, anti-hyaluronidase, and antiobesity activities. CONCLUSIONS As an important TCM, a large number of investigations have proved that EN and terpenoids isolated from EN have markedly therapeutic efficacy on diabetes, inflammation, and cancer disorders. These research findings provide modern scientific evidence for the traditional uses of EN. Moreover, more novel and active secondary metabolites from EN, as well as the in vivo and clinical in-depth tests are required in the future.

Abstract
To identify natural products as new prototypes for 5-lipoxygenase (5-LOX), 12 traditional Chinese medicines (TCMs), were selected for screening their 5-LOX inhibition activities. The results showed that all of the methanol extracts of 12 selected TCMs possessed inhibitory activities of 5-LOX at 200 μg/mL, of which six extracts of the TCMs showed significant inhibitory effects with IC50 values ranged from 33.2 ± 1.4 μg/mL to 153.5 ± 1.7 μg/mL, and the extract of Polygoni Cuspidati Rhizoma (RPC) was the most active sample. An on-line UPLC-PDA-MSn -5-LOX-FLD method was applied to further identify the potential 5-LOX inhibitory constituents in RPC extracts, which resulted in the identification of 7 components with 5-LOX-binding activities. Finally, four compounds (polydatin, resveratrol, emodin-8-O-glucoside and emodin) were successfully purified from RPC extracts. The 5-LOX inhibition action was assayed in vitro, and the results showed that these compounds possessed potent inhibitory effects against 5-LOX with IC50 values of 15.3 ± 2.1, 4.5 ± 1.2, 23.8 ± 0.4 and 11.8 ± 1.5 μg/mL, respectively. This was the first study to reveal the 5-LOX inhibitory constituents of RPC, and the present investigation might provide a valuable approach for the rapid discovery of natural inhibitors from TCMs.

Abstract
To develop the medicinal and edible plant resources of Althaea officinalis Linn in Europe and other places, this study concentrated on the bioactive ingredients of its different extracts. The phytochemical compositions of MeOH extracts were evaluated by UPLC-DAD-ESI-Q-TOF-MSn analysis. The in vitro antioxidant properties, enzymes inhibitory effects and nitric oxide (NO) production inhibitory activities of fractions obtained from the aerial parts of Althaea officinalis (APAO) were evaluated. The results identified 76 compounds, including 8 phenolic acids, 17 flavonoids, 6 coumarins, 9 triterpenes and 11 alkaloids. Fr. C-2 of APAO was found to have the highest TPC (175.8 ± 1.5 mg GAE/g) and TFC (466.9 ± 5.0 mg RE/g) with the highest antioxidant capacity in DPPH, ABTS, CUPRAC, FRAP and β-carotene bleaching assays. Fr. A showed noticeable inhibition of α-glucosidase with an IC50 value of 3.8 ± 0.1 μg/mL. However, Fr. B displayed stronger inhibitory activity on 5-lipoxygenase than quercetin, with the IC50 value of 8.4 ± 1.6 μg/mL. In addition, Fr. B also possessed potent inhibitory activities on NO production toward LPS-activated RAW 264.7 Cells with an IC50 value of 15.7 ± 1.6 μg/mL. Our findings suggest that different Althaea officinalis extracts may be considered sources of phenolic and flavonoid compounds with high potential as natural antioxidants, anti-inflammatory agents and blood sugar regulators. In addition, they can also be used in food and nutraceutical products with enhanced bioactivities.

Abstract
Nine previously undescribed butyrolactone and sesquiterpene derivatives, named cyclopentanone A (1), subamolides F and G (2 and 3), secosubamolide F (4), rupestonic acids J - L (5-7), linderaguaianols A and B (8 and 9), together with six known ones 10-15 were isolated from the roots of Lindera glauca. Their structures, including their absolute configurations were elucidated by extensive spectroscopic analysis, quantum chemical calculations, and Mo2(AcO)4-induced circular dichroism. Compound 1 that possessed a unique five-membered cyclopentane skeleton with a side chain was rarely found from natural sources. The biogenetic pathway for 1-4 was postulated. Secosubamolide F (4) inhibited nitric oxide (NO) production in lipopolysaccharide (LPS)-activated RAW264.7 cells with IC50 value of 1.73 ± 0.18 μM and also significantly suppressed the production of iNOS. The binding interactions between 4 and iNOS were investigated using docking analyses.
