Tenuifolin, a saponin derived from Radix Polygalae, exhibits sleep-enhancing effects in mice.
TLDR
These results provide the first experimental evidence of the significant sleep-enhancing effect of tenuifolin in mice. Expand
Bioactive carbazole and quinoline alkaloids from Clausena dunniana.
TLDR
Nine undescribed carbazole and quinoline alkaloids, named dunnines A-E, and 14 known analogues were isolated from the leaves and stems of Clausena dunniana and showed weak inhibitory effects on nitric oxide production stimulated by lipopolysaccharide in BV-2 microglial cells. Expand
Anti-inflammatory and cytotoxic carbazole alkaloids from Murraya kwangsiensis.
TLDR
A compound showed significant inhibition on NO production in lipopolysaccharide-stimulated BV-2 microglial cells, and four compounds exhibited moderate cytotoxicities against HepG2 cells, with IC50 values less than 20 μM. Expand
[Phytochemical and pharmacological advance on Tibetan medicinal plants of Corydalis].
TLDR
An overview focusing on the distribution, phytochemical and pharmacological results of Corydalis species that have been applied in traditional Tibetan medicinal, hopefully to provide a reference for the new Tibetan medicine development from CoryDalis plant resource. Expand
Isolation and structure characterization of cytotoxic alkaloids from Micromelum integerrimum.
Ten undescribed alkaloids, named integerrines A-J, including one racemic heterodimer of carbazole and indole, two racemic, two scalemic, and one enantiomerically enriched biscarbazoles, twoExpand
A new prenylated coumarin diglycoside with insulin-release promoting activity from Clausena dunniana
TLDR
A new prenylated coumarin diglycoside, 6-prenylcoumarin-7-O-β- D-apiofuranosyl-(1→6)-β-D-glucopyranoside and five known flavonoid glycosides were isolated from the leaves and stems of Clausena dunniana and their structures were elucidated based on comprehensive MS, UV, IR, and NMR spectroscopic data analysis. Expand
Nitric oxide inhibitory coumarins from the roots and rhizomes of Notopterygium incisum.
TLDR
Phytochemical study on the roots and rhizomes of Notopterygium incisum resulted in the isolation of six new coumarins, notoptetherins A - F, and 20 known analogues, and the absolute configurations of 5 and 6 were established by Mo2(AcO)4-induced CD and exciton chirality, respectively. Expand
Three new coumarins and a new coumarin glycoside from Micromelum integerrimum.
Three new coumarins, integmarins A-C (1-3), and a new coumarin glycoside, integmaside A (4) were isolated from the leaves and stems of Micromelum integerrimum. Their structures were elucidated on theExpand
[Chemical constituents from Murraya euchrestifolia].
TLDR
The open silica gel, ODS, and Sephadex LH-20 column chromatography was used to isolate and purify the chemical constituents from Murraya euchrestifolia, and the structures of the isolates were elucidated by their physiochemical properties, NMR, and MS spectroscopic data, as well as comparison with literature data.
