| Abstract: | Fatty acids in the Cha oil of Camellia in Sanjiang County,northern Guangxi was determined by Gas Chromatography-Mass Spectrometry. The Cha oil sample was pre-esterified potassium hydroxide-methanol before tested.Six fatty acids were isolated.They were tetradecanoic acid; 9-hexadecenoic acid; hexadecanoic acid;9,12-octadecadienoic acid; 9-octadecenoic and octadecoic acid. The content of 9-octadecenoic acid was 82.35%. |
