Lupane Triterpenes from the Leaves of Acanthopanax gracilistylus.
The phytochemical study on the leaves of Acanthopanax gracilistylus (Araliaceae) resulted in the discovery of a new lupane-triterpene compound, acangraciligenin S (1), and a new lupane-triterpene glycoside, acangraciliside S (2), as well as two known ones, 3α,11α-dihydroxy-lup-20(29)-en-23,28-dioic acid (3) and acankoreoside C (4). Their chemical structures were elucidated by mass, 1D- and 2D-n...
متن کاملSubchronic Oral Toxicity Study of Acanthopanax divaricatus var. albeofructus in Rats
Acanthopanax divaricatus (Siebold & Zucc.) Seem. var. albeofructus (ADA), a traditional medical herb, has been used to treat arthritis and muscular injury, to strengthen muscle and bone, and to get vital energy. However, information regarding its toxicity is limited. ADA was administered by oral gavage to groups of rats at doses of 0 (control), 1,000, 1,500, 2,000, 2,500, and 3,000 mg/kg five t...
متن کاملInhibition of Lung Inflammation by Acanthopanax divaricatus var. Albeofructus and Its Constituents.
In order to find potential therapeutic agents on lung inflammatory conditions, the extracts of Acanthopanax divaricatus var. albeofructus were prepared and its constituents were isolated. They include lignans such as (+)-syringaresinol (1), acanthoside B (2), salvadoraside (3) and acanthoside D (4), lariciresinol-9-O-β-D-glucopyranoside (5) and phenylpropanoids such as 4-[(1E)-3-methoxy-1-prope...
متن کاملPhotoprotective Potential of Anthocyanins Isolated from Acanthopanax divaricatus Var. albeofructus Fruits against UV Irradiation in Human Dermal Fibroblast Cells
Ultraviolet (UV) A penetrates deeply into the skin and induces the generation of reactive oxygen species (ROS) causing damage to fibroblasts, which leads to aging of the skin. However, the body has developed an antioxidant defence system against the harmful effects of ROS. Enzymes such as superoxide dismutase (SOD) and catalase (CAT) play critical roles on the removal of excess ROS in living or...
متن کاملLupane-triterpene glycosides from the leaves of Acanthopanax gracilistylus.
A novel lupane-triterpene glycoside, called wujiapioside B (1), was isolated from the leaves of Acanthopanax gracilistylus (Araliaceae) together with three known lupane-triterpene glycosides, acankoreoside C (2), acantrifoside A (3) and 3-epibetulinic acid 28-O-alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester (4). Based on spectroscopic data, the chemica...
