daucosterol/인삼속

Six saponins with low sugar chain were isolated from the leaves of Panax notoginseng (Burk) F. H. Chen. Their structures were elucidated as 20(R)-ginsenoside Rh2(I), 20(R)-ginsenoside Rg3(II), ginsenoside Mc(III), ginsenoside F1(IV), ginsenoside Rh1(V) and daucosterol(VI) by spectroscopic analysis

OBJECTIVE To investigate chemical constituents from the ripe fruit of Panax ginseng. METHODS The compounds were isolated and purified by chromatographic methods such as macroporous resin, sephadex LH-20, Bio-gel P-2, ODS and silica gel. Their structures were identified by their physical and spectral

For the purpose of clarification of pharmacological actions of ginseng saponins we tried the isolation of ginseng saponins on a larger scale and succeeded in the isolation of eight saponins in a pure state and in sufficient amounts for the pharmacological assay. These eight saponins agreed all
