P-Sitosterol-glucoside

The detection of triterpenoid compounds in extracts from Bidens pilosa may rationalize the use of this plant in traditional Egyptian medicine in the treatment of wounds and against bacterial infections of the gastrointestinal tract [211,212]. The chloroform extract gave 3-amyrin. Fig. (29), phytosterin B and P-sitosterol glucoside, while the petroleum ether extract afforded P-am5Tin, Fig. (29), phytosterin B, lupeol. Fig. (30), lupeol acetate, linolic acid and linolenic acid. The antimicrobial test was carried out to indicate an evident activity.

From B. tricuneata collected in the surroundings of Santafe de Bogota (Colombia), several triterpenoids, e.g. p-sitosterol, a-amyrin acetate, friedelin, Fig. (25) and ursolic acid, Fig. (26) were also reported [59], while the species B. coridifolia yielded schottenol glucoside, Fig. (27), uvaol, Fig. (28) and ursolic acid, Fig. (26) [60],... 

Steroids are widespread in nature, and those present in Aristolochia species are mostly derivatives of P-sitosterol and stigmasterol. P-Sitosterol (610) and its glucoside (611) were frequently encountered in several Aristolochia species (Table 22). P-Sitosterone (612), 3-one derivative of P-sitosterol was found in A. zollingeriana only [245], Stigmasterol (613) and its derivatives stigmast-4-en-3-one (614), 3P-...

The mature seeds of C. speciosus were reported to contain an appreciable amount of diosgenin [123]. Numerous steroidal saponins were isolated from the seeds [124]. Their structures were elucidated as P-sitosterol-P-D-glucoside, prosapogenin A and B of dioscin, dioscin, gracillin, 3-0-[a-L-rhamnopyranosyl(l —> 2)-P-D-glucopyranosyl]-26-0-[P-D-glucopyranosyl]-22-a - methoxy - (25/ ) - furost-5 - en-3p, 26-diol... 

The rhizomes of C. lacerus were found to contain an appreciable amount of diosgenin [129]. The steroidal saponins of the rhizomes were identified as P-sitosterol-P-D-glucoside, prosapogenin A of dioscin, dioscin and gracillin [129]. 

From the ether-soluble fraction, Takahashi etal. 134, 135) isolated sitosterol-P-D-glucoside, sitosterol, p-elemene (96), eremophilene (97) and a new polyacetylenic alcohol named panaxynol (98), the structure of which was elucidated as heptadeca-l,9(Z)-diene-4,6-diyn-3-ol by degradative and synthetic procedures. It is identical with carotatoxin from carrots 136) and falcarinol from Falcaria vulgaris 137). Recently two other polyacetylenic alcohols, 9,10-epoxy-3-hydroxyheptadeca-l-en-4,6-diyne [(99), panaxydol] 138) and heptadeca-l-en-4,6-diyn-3,9-diol (100) 139) were isolated from Ginseng roots by Wrobel et al.
