Pharmacological studies: The Rhizoma Dioscoreae Hypoglaucae contained in rhizomes of hawthorn has insecticidal effects. Dioscin saponins, kruselin glycosides also have antifungal effects.
[chemical composition] Rhizoma Dioscoreae Hypoglaucae main diosgenin containing saponin, still containing fine yam, diosgenin saponin glycoside A (the saponins of the above saponins are diosgenin), hawthorn saponin, jonosaponin, saponins yuan - 1-Glucosinone and other saponins. Diosgenin is a pesticidal ingredient in hawthorn. The diosgenins isolated from roots include diosgenin, trimethoprim, triammonium saponin, triamcinolone saponin, triamcinolone saponin and capsid saponin. A small amount of 25-iso-spirofluorene-3,5-diene was also isolated, which may be the dehydration product of diosgenin when it is hydrolyzed. The above-mentioned parts of the ground contain the saponins, saponins, and saponins. Apart from seeds, the aerial parts contained considerable amounts of free jonosaponins and tocopherols. The underground part has traces of free diosgenin, all of which are saponins. The seed contains tolsaponin, and its aglycone is almost completely present as a saponin. Diosgenin, jonosaponin, tocoside and capsid saponin were isolated from female flowers. Diosgenin, sinosaponin, tocoside, and galenicin were isolated from male flowers.
