Crystallise -sitosterol from EtOH, MeOH, Me2CO, Me2CO/EtOH or Me2CO/MeOH. It has also been purified by zone melting. The acetate crystallises from MeOH or EtOH as plates with m 127128o and [] D 20 -41o (c 2, CHCl3). The benzoate crystallises from EtOH as needles with m 146...
-Sitosterol and -sitosteryl- D -glucoside were isolated from coastal Bermuda grass and from orchard grass, and identified by infrared spectra and physical constants on the sterol and the acetate. Palmitic acid was isolated from the saponifiable fractions. No saponin was detected....
Further, PI and PII was separated in precoated TLC plates (Merck, Germany) using binary mobile phase of 10% ethyl acetate in petroleum ether and 30% acetone in chloroform respectively. Identification of active constituents by LC-MS-MS The active sub-fractions obtained from TLC were subjected ...
