Costus speciosus

Terpenoid compounds of varying structural skeletons have already been reported to possess significant antidiabetic potential. Promising terpenoidal constituents obtained from different natural sources, particularly medicinal plants are summarized herein. Costunohde (52), a terpenoid constituent of Costus speciosus (Koen ex.Retz.)Sm. (family Zingiberaceae), was found to reduce plasma glucose in a dose-dependent manner (p < 0.05). In... [Pg.536]

New sources for diosgenin are constantly being developed in the tropics. A promising species is Costus speciosus (J.G.Koenig), Smith, family Costncecte, which now is cultivated in India and Thailand, while Tri onella,foenum— mecum has received attention in countries with temperate climates. [Pg.91]

Diosgenin, recently isolated in high yield from the rhizomes of Costus speciosus, " is microbiologically hydroxylated by Cunninghamella blakesleeana to 7 -hydroxy-, 7/5,1 la-dihydroxy-, and 7/5,12/8-dihydroxy-diosgenin and oxidised by Mycobacterium phlei to mixtures of A" - and A -3-ketones. [Pg.482]
