Stress Enhances Indole 3 - butyric Acid - induced Rooting in Bupleurum falcatum L . ( Saiko ) Root Culture
Ildole 3 butyric acid (IBA) at 8rng l i induced, vigorous rooting in Bupleurum falcatum L. (Saiko) root culture in B5 medium after about 2weeks, when it was added at the time when detached roots were transferred to fresh medium. The rooting activity markedly decreased with delay of IBA addition after root 2transplantation, and was hardly observed when IBA was added at the 7th day. Stresses such...
متن کاملThe Complete Chloroplast Genome of the Hare’s Ear Root, Bupleurum falcatum: Its Molecular Features
Bupleurum falcatum, which belongs to the family Apiaceae, has long been applied for curative treatments, especially as a liver tonic, in herbal medicine. The chloroplast (cp) genome has been an ideal model to perform the evolutionary and comparative studies because of its highly conserved features and simple structure. The Apiaceae family is taxonomically close to the Araliaceae family and ther...
متن کاملCombinatorial biosynthesis of sapogenins and saponins in Saccharomyces cerevisiae using a C-16α hydroxylase from Bupleurum falcatum.
The saikosaponins comprise oleanane- and ursane-type triterpene saponins that are abundantly present in the roots of the genus Bupleurum widely used in Asian traditional medicine. Here we identified a gene, designated CYP716Y1, encoding a cytochrome P450 monooxygenase from Bupleurum falcatum that catalyzes the C-16α hydroxylation of oleanane- and ursane-type triterpenes. Exploiting this hithert...

15 صفحه اولAntioxidant and Protective Effects of Bupleurum falcatum on the L-Thyroxine-Induced Hyperthyroidism in Rats
Bupleuri Radix (BR), the dried roots of Bupleurum falcatum L., has been used in folk medicine as an antiinflammatory and antioxidative agent. The aqueous extract of BR was evaluated for its possible ameliorative effect in the regulation of hyperthyroidism in l-thyroxine- (LT4-) induced rat model. After oral administration of 300, 150, and 75 mg/kg of BR extracts, once a day for 15 days from 12t...
