A composition and proportion of delta -7 phythosterols in non saponifiable part of pumpkin seed oil extracted from Cucurbia peppo var striaca, and extracted oil from Peponen capsules were determined using GC- Mass with stigmastherol as Iran standard.
Delta 7-phythosterol concentration as calculated from GC-Mass spectra is 38-67. mg % in striaca cultivated in iran and. 78-82 mg% in extrected oil. From Peponen.
