[Study on the chemical constituents of the roots of commercial ginseng].
OBJECTIVE
To isolate and elucidate the constituents from the roots of Commercial Ginseng.


METHODS
Column chromatography and HPLC were used to isolate chemical constituents. Physico-chemical characters and spectr-oscopic analysis were employed for structural identification.


RESULTS
Sixteen compounds were identified as: notoginsenoside-R2(1), ginsenoside-Rg2(2), 20 (R)-Rg2 (3), ginsenoside-Rg1 (4), -Rf(5), -Re(6), -Rd(7), -Rc(8), -Rb1(9), -Rb2(10), -Rb3(11), -Ra3(12), -Ra2(13), -Ra1 (14), notoginsenoside-R4(15) and ginsenoside -Ro(16).


CONCLUSIONS
Compound 1 was obtained from the plant for the first time.
