ABSTRACT
Two new dammarane-type triterpenoids, notoginsenoside SY1 (1) and notoginsenoside SY2 (2), were isolated from the stems and leaves of Panax notoginseng. Their structures were elucidated to be 3ß, 12ß-dihydroxy-22, 23, 24, 25, 26, 27-hexanordammarane-20-one 3-O-ß-D-xylopyranosyl-(1â2)-O-ß-D-glucopyranosyl-(1â2)-O-ß-D-glucopyranoside (1), 3ß, 12ß-dihydroxy-20S, 24 R-epoxydammar-25-ene 3-O-ß-D-xylopyranosyl-(1â2)-O-ß-D-glucopyranosyl-(1â2)-O-ß-D-glucopyranoside (2) by IR, HRESIMS and NMR experiments.[Formula see text].
