presenegenin/イトヒメハギ

OBJECTIVE To research the germplasm resources and the contents of senegenin in processing products of Polygala tenuifolia. METHODS The contents of senegenin in wild Polygala tenuifolia and cultivated samples of Polygala tenuifolia were determined by RP-HPLC, and compared. RESULTS The contents of

Two new acylated presenegenin glycosides E-onjisaponin H (5) and Z-onjisaponin (6) together with seven known saponins were isolated from the roots of Polygala tenuifolia Willd. Compounds 5 and 6 were obtained as a pair of isomers due to trans and cis-p-methoxycinnamoyl. Their structures were

A new triterpenoid saponin, tenuifoside A, was isolated together with three known triterpenoid saponins 2, 3, and 4 from the roots of Polygala tenuifolia Willd. With the help of chemical and spectral analyses (IR, MS, 1D-NMR, and 2D-NMR), the structure of the new saponin was elucidated as

OBJECTIVE To study the chemical constituents from the roots of Polygala tenuifolia. METHODS Column chromatographic techniques were employed for isolation and purification of chemical constituents of the plant and the structures were elucidated by spectroscopic analysis. RESULTS Five chemical
