Sesquiterpene glycosides from Dictamnus dasycarpus
Phytochemistry 47(1) (1998)
63-68
Five novel sesquiterpene glycosides named dictamnosides A-E were isolated from the methanol extract of the root bark of Dictamnus dasycarpus. Their structures were established on the basis of X-ray diffraction, spectroscopic and chemical methods.

Triterpenoid glycosides from Adina rubella
Phytochemistry 39(5) (1995)
1241-1243
Two new triterpenoid glycosides, quinovic acid-3β-O-β-D-glucopyranosyl-(1→4)-α-L-rhamnopyranoside and quinovic acid-3β-O-β-D-glucopyranosyl-(1→3)-β-D-fucopyranoside (named rubelloside A and B, respectively), were isolated from roots of Adina rubella. Their structures were elucidated by spectral and chemical means. Rubelloside B exhibited immunological enhancement.
