ACYL STERYL GLYCOSIDES FROM PITHECELLOBIUM-CAULIFLORUM

One sterolglycoside and two sterolglycolipids, were found in the branc hes of Pithecellobium cauliflorum (Willd.) Mart., namely the beta-D-gl ucoside 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 (acylglucosylsterol s, major components). Each was isolated and identified by a combinatio n of different chromatographic, hydrolytic and spectroscopic methods, respectively. (C) 1998 Published by Elsevier Science Ltd. All rights r eserved.
