As. Stolyarenko et al., Triterpene glycosides of Scheffleropsis angkae. I. Structure of glycosidesL-B-1, L-B-2, L-H-1, and L-H-2, CHEM NAT CO, 36(2), 2000, pp. 173-176
The structures of four triterpene glycosides from the leaves of Schefflerop
sis angkae (Araliaceae) are found by chemical methods and NMR spectroscopy
to be the 3-O-alpha -L-arabinopyranosides of oleanic and ursolic acids and
their 28-O-alpha -L-rhamnopyranosyl-(1-4)-O-beta -gentiobiosyl esters, whic
h are designated L-B-1, L-B-2, L-H-1, and L-H-2, respectively. The glycosid
e L-H-2 is new.
