schisantherin d/schisandra

Three new 7,8-secolignans, schisandlignans A-C (1, 2, and 4), one new dibenzocyclooctadiene lignan, schisandlignan D (5), together with nine known lignans 3',4'-dimethoxybenzoic acid (3″,4″-dimethoxyphenyl)-2-methyl-3-oxobutyl ester (3), gomisin J (6), rubrisandrin A(1b) (7), interiotherin B (8),

OBJECTIVE To study the chemical constituents in the fruits of Schisandra sphenanthera. METHODS The constituents were isolated by their silica gel column, Sephadex LH-20 gel column, and their structures were elucidated by their chemical properties and spectroscopic analyses. RESULTS Twelve compounds

The fruit of S. sphenanthera, known as "Nanwuweizi", has been widely used as traditional Chinese medicine for several thousand years. However, the current determination methods are not sufficient to evaluate its quality. An accurate, sensitive and reliable high performance liquid chromatography

Chemical investigation into the stems of the medicinal plant Schisandra sphaerandra led to the isolation and identification of a new dibenzocyclooctadiene lignan sphaerandrin A (1) and 11 known ones gomisin B (2), schirubrisin B (3), kadsuphilin B (4), schizandrin

This study was performed to use UHPLC-QTOF/MSE technology to rapidly search and identify variations of chemical ingredients between Fructus Schisandrae Chinensis and its processed products. The present study provides a basis for the study of Chinese herbal medicine processing with a focus on the
