Acyl steryl glycosides from Pithecellobium cauliflorum
1998
Gomes, D. de C.F. | Alegrio, L.V.
One sterolglycoside and two sterolglycolipids, were found in the branches of Pithecellobium cauliflorum (Willd.) Mart., namely the beta-D-glucoside of alpha-spinasterol (glucosylsterol, minor component), 3-O-[6'-O-palmitoyl-beta-D-glucosyl]-spinasta-7, 22(23)-diene, and 3-O-(6'-O-stearoyl-beta-D-glucosyl]-spinasta-7, 22(23)-diene (acylglucosylsterols, major components). Each was isolated and identified by a combination of different chromatographic, hydrolytic and spectroscopic methods, respectively.
