Two new spirostane saponins namely (25 R)-6α-[(β-D-glucopyranosyl)oxy]-5α-spirostan-3β-yl β-D-galactopyranoside (1) and (25 R)-6α-[(β-D-glucopyranosyl)oxy]-27-hydroxy-5α-spirostan-3β-yl β-D-glucopyranoside (2), together with three known metabolites (25 S)-5β-spirostan-3-β-yl O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside (3), (25 R)-5α-spirostan-3-β-yl O-β-D-galactopyranosyl-(1→2)- O-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside (4) and (25 R)-5α-spirostan-3-β-yl O-β-D-glucopyranosyl-(1→3)- O-[β-D-xylopyranosyl-(1→2)]- O-β-D-glucopyranosyl-(1→4)-β-D-glactopyranoside (5) were identified from the leaves of Asparagus sprengeri Regel (Asparagaceae). Determination of the structures was based on chemical and spectroscopic data (HRESI-MS/MSn, 1H, DEPT 13C NMR, 1H-1H COSY, HSQC and HMBC). The dry powder, the 1-butanol extract of the leaves, and the isolated compounds (3–5) exhibited molluscicidal properties against Biomphalaria alexandrina snails (the intermediate host of Schistosoma mansoni) [LC90 = 150, 40, 7, 10 and 13 ppm, respectively], while compounds 1 and 2 were molluscicidally inactive.

Adult Trematode

It has been found by use of electrophoresis that the hepatopancreas of the snail Biomphalaria alexandrina (Ehrenberg) contains one phosphoglucoseisomerase. Snails which have secondary sporocysts of the trematode Schistosoma mansoni contain an additional phosphoglucoseisomerase which is also found in the adult trematode. It is supposed that the secondary sporocysts are secreting phosphoglucoseisomerase into the hepatopancreas of the snail in order to increase the transformation of glycogen to simpler carbohydrates, in which form the parasite is able to absorb the carbohydrates necessary for metabolism.
