Objective:
To study the chemical constituents from rhizomes of Panax notoginseng.
Methods:
The constituents were isolated and purified by various chromatogragraphic methods, all compounds were identified on the basis of special analysis and physicochemical characters.
Results:
Eight compounds were isolated from the 80% alcohol extract of the rhizomes and their structures were identified as ginsenoside Rh4 (I), ginsenoside Rh1 (II), ginsenoside Re (III), notoginsenoside R1 (IV) , ginsenoside Rd (V), ginsenoside Rh1 (VI), notoginsenoside S (VII), notoginsenoside T (VIII).
Conclusion:
Compound I was isolated from this plant for the first time, Compound VII, VIII are isolated from rhizomes of Panax notoginseng for the first time.
