摘要：

The roots of Primula veris subsp. macrocalyx have yielded three new triterpenoid saponins which have been characterized as 3-O-{[alpha-L-rhamnopyranosyl-(1 --> 2)-beta-D-galactopyranosyl-(1 --> 3)]-[beta-D-glucopyranosyl-(1 --> 2)]-beta-D-glucuronopyranosyl}-priverogenin B 22-acetate (priverosaponin B 22-acetate) [1], 3-O-{[alpha-L-rhamnopyranosyl-(1 --> 2)-beta-D-galactopyranosyl-(1 --> 3)]-[beta-D-glucopyranosyl-(1 --> 2)]-beta-D-glucuronopyranosyl}-priverogenin B(priverosaponin B)[2], and 3-O-{[alpha-L-rhamnopyranosyl-(1 --> 2)-beta-D-galactopyranosyl-(1 --> 3)]-[beta-D-glucopyranosyl-(1 --> 2)]-beta-D-glucuronopyranosyl}-anagalligenin A(primacrosaponin)[3]. By contrast, the main saponin isolated from Primula elatior subsp. meyeri was 3-O-{[alpha-L-rhamnopyranosyl-(1 --> 2)-beta-D-galactopyranosyl-(1 --> 3)]-[beta-D-glucopyranosyl-(1 --> 2)]-beta-D-glucuronopyranosyl}-protoprimulagenin A [4], primulasaponin. Structure elucidations were carried out both chemically and spectroscopically.
