Halosterols A and B, chymotrypsin inhibitory sterols from Haloxylon recurvum.
Two new sterols, halosterols A (1) and B (2), have been isolated from the CHCl(3) soluble fraction of Haloxylon recurvum, and their structures were elucidated by spectroscopic techniques including two dimensional-NMR. Both the compounds displayed chymotrypsin enzyme inhibitory potential.
