Abstract Six new monoterpene glycosides, named 6′-O-nicotinoylalbiflorin (1), 4′-O-vanillylalbiflorin (2), paeonidanin L (3), paeoniflorigenin-1-O-β- d -xyloside (4), 6′-(2-hydroxypropanoyl)-paeoniflorin (5), oxylactiflorin (6), together with 16known ones (7–22) were isolated from the 70% ethanol extract of Paeoniae Radix. Their structures were elucidated based on spectroscopic analysis (1D and 2D NMR, HRESIMS, IR and UV), chemical evidences and comparison with literatures. The inhibitory effect...

Abstract Endophytic have been considered a rich source for bioactive secondary metabolites with novel chemical structures. A high diverse group of endophytes, isolated from different medicinal plants, belongs to the genus Diaporthe . In a previously study performed by our group the crude extract of strain LGMF1583 showed considerable antibacterial activity mainly against Gram-negative bacteria. Based on ITS phylogeny analysis, strain LGMF1583 was identified as belonging to Diaporthe genus and ma...

Abstract Thirty-one compounds were obtained and identified from the dried roots of Mongolian medicinal and edible plant, Pugionium cornutum L. Gaertn. Eight of them were new ones, and named as pugcornols A (1), B (2), C (3), and D (4), pugcornosides A (5), B (6), C (7), and D (8), respectively. Among them, 1–4 were rare naturally occurring thiohydantoin derivatives. Meanwhile, all the isolates were determined for their activities on isolated mice jejunum contraction, and ten of them increased he...

Abstract The Alpine wormwood Artemisia vallesiaca All. was considered the most valuable ingredient of vermouth, a celebrated aromatized wine. A. vallesiaca has a very limited geographical distribution, and the booming market of vermouth decimated its natural population, resulting in the eventual replacement of this rare species with more common and less expensive wormwoods like A. absinthium L.. Over the past years, attempts to revive the original recipe(s) of vermouth have fostered the establis...

Abstract Three newly isolated ergosterols, psathergosterols A–C (1–3), together with two known ones (4 and 5), have been isolated from cultures of the basdiomycete Psathyrella candolleana. Their structures with the absolute configuration were elucidated by means of spectroscopic methods and the single crystal X-ray diffraction. Compounds 2–4 exhibited certain cytotoxicities to five human cancer cell lines (HL-60, SMMC-7721, A-549, MCF-7, SW480).

Abstract Gerbera piloselloides (L.) Cass. (Compositae) possesses various biological effects. It is used as an oriental remedy for relieving cough and resolving phlegm. The present study is to investigate the vasodilation effects of Gerbera piloselloides on isolated rat mesenteric arteries (MAs) and the potential mechanism. Different organic extracts of Gerbera piloselloides were tested, and an HPLC-UV-FD-based analytical method was established to identify the active constituents. The principal c...

Abstract Four new sesquiterpenes (1–2, 6–7), a new pyranone glycoside (10) along with six known compounds, were isolated from the whole plant of Erigeron breviscapus. Their planar structures were elucidated using extensive spectroscopic analyses. Brevisterpene A (1) and brevisterpene B (2) were proved to be a pair of diastereomer followed by mixtures resolution using chiral HPLC. Their absolute configurations were determined by ECD calculation. The relative configuration of brevisnoside B (7) wa...

Abstract Five new metabolites, including two monoterpene glycosides Pubescenosides L–M (1–2) and three phenolic glycosides, Pubescenosides N-P (3–5), along with nineteen known ones, including liganoids, hemiterpenoids and caffeoylquinic acid derivates, were isolated from the roots of Ilex pubescens. Their structures were elucidated from extensive spectroscopic analysis, including 1D and 2D NMR experiments. This study is the first to report monoterpene glycosides with β-pinene aglycone in Aquifol...
