rhamnopyranosyl - (1→2) - α - L- arabinpyranosyl] - hederagenin (2), 3 – O – [ α – L – rhamnopyranosyl – (1→2) – α - L -arabinpyranosyl]-
28-O-β-D-glucopyranosyl hederagenin (3), 3-O-[α-L-rhamnopyranosyl-(1→2)-α-L-arabinpyranosyl]-28-O- [β-D-glucopyranosyl-(1→6)-β-Dglucopyranosyl]
hederagenin (4), and 3-O-[α-L-rhamnopyranosyl-(1→2)-α-L-arabinpyranosyl] -28-O-[α-L-rhamnopyranosyl-(1→4)-β-Dglucopyranosyl-(
1→6)-β-D-glucopyranosyl] hederagenin (5), were isolated from the active extracts of the seeds of Nigella glandulifera Freyn.
Compounds (3), (4), (5) were isolated from the plants of the Nigella genus for the first time.
