Ding Y, Chen YY, Wang DZ, Yang CR
Steroidal saponins from a cultivated form of Agave sisalana
Phytochemistry 28 (1989)
2787-2791
Three new steroidal saponins, dongnosides C-E, were isolated from the methanol extracts of the fermented residues of leave-juices of Agave sisalana form Dong No 1. On the basis of chemical and spectral evidence, the structures of dongnosides E, D and C were determined as tigogenin-3-O-β-d-xylopyranosyl(1→2)[β-d-glucopyranosyl(1→3)]β-d-glucopyranosyl(1→4)β-d-galactopyranoside, tigogenin-3-O-β-d-xylopyranosyl(1→3)β-d-xylopyranosyl(1→2)[β-d-glucopyranosyl(1→3)β-d-glucopyranosyl(1→4)β-d-galactopyranoside and tigogenin-3-O-α-l-rhamnopyranosyl(1→4)β-d-xylopyranosyl(1→2)[β-d-glucopyranosyl(1→3)]β-d-glucopyranosyl(1→4)β-d-galactopyranoside, respectively.

Two new steroidal saponins from dried fermented residues of leaf-juices of Agave sisalana forma Dong No. 1
Chemical and Pharmaceutical Bulletin 41(3) (1993)
557-560
In a previous paper, we peported the isolation and structure determination of three new steroidal saponins, dongnosides C (3), D (2) and E (1) from the dried fermented residues of leaf-juices of Agave sisalana forma Dong No. 1. In a continuing study on this plant, two additional new major steroidal saponins, named dongnosides B (4) and A (5), were obatained. Their structures were characterized respectively as tigogenin 3-O-α-L-rhamonpyranosyl-(1→4)-β-D-glucopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→3)]-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside and 3-O-α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→3)-β-D-glucopyranosyl-(1→3)]-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside on the basis of chemical and physicochemical evidence.
