| Abstract: | The organic acids in Hovenia dulcis Thunb peduncle were methylated,and then analyzed by a gas chromatography-mass spectrometry. 19 acidic compounds were identified and they represent 97.11% of the total peak aeras. 9 compounds of them belong to polyhydric acids and 10 of them belongs to fatty acids. The results showed that malic acid was the highest amount component of these compounds and it represents over 22.88%. There are many kinds of unsaturated higher fatty acids in Hovenia dulcis Thunb peduncle and the total content of them was 9.71%. The content of linolenic acid and linoleic acid were 5.06% and 3.35% respectively. |
