cytellin and argyrophilic-acid

To study the constituents of Cacalia ambigua.. The chemical constituents were isolated from the plant by all kinds of column chromatographies and their structures were identified by spectral methods.. Four compounds were isolated and identified as ent-kaur-16-en-19-oic acid (1), 13-beta-Kaur-16 beta-ol (2), beta-sitosterol (3) and 1-glyceryl nonadecanoic acid ester (4).. Compounds 1-4 are isolated from this plant for the first time, and compounds 1 and 2 and isolated from this genus for the first time.

Eight components were isolated and purified from the ethereal extract from cultivar Aralia cordata Thumb. By means of UV, IR, 1H-NMR, 13CNMR, they were identified as (I) kaur-16-en-19-oic acid, (II) docosanoic, (III) hexadecanoic acid, (V) stigmasterol, (V) 16-formyl-kaur-15-en-19-oic acid, (VI) 7-oxo-ent-pimara-8 (14), 15-dien-19-oic acid, (VII) 17-Hydroxy-ent-kaur-15-en-19-oic acid, (VlII) sitosterol. Among them, components II, III, V were isolated from the gunus of Aralia for the first time.

Seven compounds were isolated from the roots of Aralia continentalis. Four of these compounds were identified as ent-kaur-16-en-19-oic acid, beta-sitosterol glucoside (daucosterol), beta-sitosterol and 16 alpha-hydroxy-(-)-kauran-19-oic acid. It is the first time that 16 alpha-hydroxy-(-)-karan-19-oic acid and beta-sitosterol glucoside were isolated from this plant.
