Two new podophyllotoxin glucosides from Sinopodophyllum emodi (Wall.) Ying.
Two new aryltetralin-type lignans, isopodophyllotoxin 7'-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside (1) and 4-demethyl-picropodophyllotoxin 7'-O-beta-D-glucopyranoside (2), along with eight known podophyllotoxin derivatives: 4-demethyl-podophyllotoxin 7'-O-beta-D-glucopyranoside (3), podophyllotoxin 7'-O-beta-D-glucopyranoside (4), deoxypodophyllotoxin (5), picropodophyllotoxin (6),...
متن کاملLabdane Diterpenes from the Fruits of Sinopodophyllum emodi.
Two new labdane diterpenes, sinoditerpene A (1) and B (2), were isolated from the fruits of Sinopodophyllum emodi, along with two known analogues 3 and 4. Their structures were established on the basis of extensive spectroscopic analysis. The isolation of compounds 1-4 represents the first report of diterpenes from the genus Sinopodophyllum. The cytotoxic activities of all isolated compounds we...
متن کاملStudies on the structural characterization of compounds in Sinopodophyllum emodi and their inhibitory effect on K562 cell proliferation
Sinopodophyllum emodi is a herbaceous perennial plant. It is used in the treatment of hemopathy, retained placenta and lochiorrhea. Its root contains podophyllotoxin, which has an anti-tumor effect. Compounds were isolated by column chromatography, and were analyzed by NMR chromatography; flow cytometry was used to determine the anticancer activity of ethanol extract of Sinopodophyllum emodi. T...
متن کاملTwo new phenolic glucosides from Lagerstroemia speciosa.
Two new phenolic glucosides, 1-O-benzyl-6-O-E-caffeoyl-β-d-glucopyranoside and 1-O-(7S,8R)-guaiacylglycerol-(6-O-E-caffeoyl)-β-d-glucopyranoside, were isolated from the aerial parts of Lagerstroemia speciosa, along with ten known compounds. The structures of the isolated compounds were determined based on 1D- and 2D-NMR, Q-TOF MS and optical rotation spectroscopic data. All of the compounds sho...
متن کاملN-GLUCOSIDES: NEW PHASE-II METABOLITES OF TWO BARBITURATES
The new phase-II N-glucoside metabolites of butobarbitone and pentobarbitone are identified and quantified in human urine after single doses of these drugs. The identification and quantification of these metabolites were carried out by mass spectroscopy technique (accurate mass measurement and high voltage scanning). It was found that the butobarbitone N-glucoside comprised 26% of the dos...
