Eudesmane derivatives and other sesquiterpenes from Laggera alata.
TLDR
Three new eudesmane sesquiterpenes, 5 beta-hydroxyilicic acid (1), 5 alpha-hydroxyl-4-epi-ilicic Acid methyl ester (2), and 3 alpha-HydroxyilicIC acid (3) were isolated from the aerial part of Laggera alata and elucidated primarily by NMR and mass spectroscopic methods. Expand
[Chemical constituents from medical and edible plants of Rosa roxburghii].
TLDR
In the course of the continuing search for the bioactive constituents, thirteen compounds were isolated from R. roxburghii, and their structures were determined on the basis of physicochemical property, spectroscopic data and comparison with the literatures. Expand
A petrol ether extract of the roots of Onosma paniculatum induces cell death in a caspase dependent manner.
TLDR
A petrol ether extract showed significant growth inhibitory effect, cell cycle influence and caspase-3 dependent induction of apoptosis which was time and dose dependent. Expand
Seco-pregnane steroidal glycosides from the roots of Cynanchum atratum and their anti-TMV activity.
TLDR
Fifteen new seco-pregnane steroidal glycosides cynanosides A-O (1-15) together with twenty-seven known ones were isolated from the roots of Cynanchum atratum and most of them showed potent anti-TMV activity. Expand
Minor furofurano lignans from the Tibetan herb, Lancea tibetica.
Four new furofurano lignans, lantibesides B - D ( 1 - 3) and lantibetin ( 4), along with nine known phenolic compounds were isolated from the EtOH extract of the traditional Tibetan medicinal plant,Expand
Four new constituents from Taraxacum mongolicum
Two new flavone glycosides, isoetin-7-O-beta-D-glucopyranosyl-2'-O-alpha-L-arabinopyranoside (1) and isoetin-7-O-beta-D-glucopyranosyl-2'-O-alpha-D-glucopyranoside (2), a new lignan, mongolicumin AExpand
Effects of spiramine T on antioxidant enzymatic activities and nitric oxide production in cerebral ischemia–reperfusion gerbils
TLDR
The results suggested that the neuroprotective effects of spiramine T were related to modulation of endogenous antioxidant enzymatic activities and reduction of the formation of nitric oxide. Expand
Cytotoxic and antioxidative phenolic compounds from the traditional Chinese medicinal plant, Myristica fragrans.
TLDR
Two new phenolic compounds were isolated from the fruits of Myristica fragrans and their structures were elucidated and the absolute configuration of (+)-Delta8'-7-acetoxy-3,4,3',5'-tetramethoxy-8- O-4'-neolignan was determined for the first time through spectroscopic and chemical methods. Expand
New diterpenoids from the roots of Euphorbia ebracteolata Hayata
TLDR
Three new diterpenoids, ingenol-5β,20-O,O-isopropylidene-3β-palmitate, 3β,19-dihydroxy-1(10),15-rosadien-2-one (3), were isolated from the roots of Euphorbia ebracteolata Hayata. Expand
Studies on cytotoxic pregnane sapogenins from Cynanchum wilfordii.
TLDR
To investigate their cytotoxicity, seventeen C21-steroidal pregnane sapogenins 1-17 were isolated from the hydrolytic extracts of the roots of Cynanchum wilfordii, and a new aberrant pregnane skeleton with ether linkage between C-12 and C-20 were found for the first time. Expand
