橡胶种子活性物质探讨（GC-MS) . Study on Active Constituents of Seeds of Hevea brasiliensis

Abstract

Hevea brasiliensis seeds of42clones were collected around Hainan Island.They contained38%52%in the kernel extracted by ether.The seed oil of 12clones was analyzed by GC/MSD.T he results showed that the seeds contained25.24%saturated and74.52%unsaturated fatty acids.T he saturated fatty acids were tetradecanoic acid,hexadecanoic acid and octadecanoic acid.The u nsaturated fatty acids were oleic acid(21.55%),linoleic acid(35.25%)andα-linolenic acid(17.72%).The seed oil of 30clones was analyzed by GC/MSD to determine sterols.The results showed that the highest sterols content was12.02%,29times more than that of the soybean oil.
