皱皮木瓜鲜果挥发油成分及脂肪酸组成分析

Analysis on composition of volatile oil and Fatty Acids in Fresh Fruit of chaenomeles speciosa

摘要:

本研究以巴东县皱皮木瓜为试验材料 , 用水蒸气蒸馏法提取成熟期干燥条件下皱皮木瓜的挥发油和脂肪酸 , 用 GC-MS获得其挥发油和脂肪酸各成分的总离子流图谱 , 结合计算机检索技术对化合物进行结构鉴定 , 分离鉴定了挥发油 70个化合物 , 结果表明 , 其相对含量≥5%的成分为 L-抗坏血酸-2, 6-二棕榈酸酯、α-金合欢烯、3-辛基-顺式环氧己烷基甲 酯、亚油酸乙酯;分离鉴定脂肪酸成分 15个 , 其相对含量≥5%的成分为14-甲基-十五酸甲酯、邻苯二 甲酸二异丁酯、十八酸 甲酯、顺-别香橙烯、[1S-(1α , 3Aβ,4α , 8Aβ)]-十氢-4, 8, 8-三 甲基-9-亚甲基-1, 4-亚甲基奥-长叶烯 。试验证明皱皮木瓜中所 含的高级不饱和脂肪酸在降血脂、抗氧化、抗炎等多个方面显示出显著的药理活性。

Abstract:

chaenomeles speciosa were used as experimental material in Badong county , The author extracted the volatile oil and fatty acids of chaenomeles speciosa under dry conditions during the mature period using steam distillation . The to- tal ion flow spectra of the components of the volatile oil and fatty acids were obtained using Gc-MS. combined with com- puter retrieval technology , the structure of the compounds was identified , and 70compounds of the volatile oil were sepa- rated and identified. The components with a relative content ≥5% were L-ascorbic acid-2, 6-dipalmitate , α-Acaciene , 3- octyl-cyclohexanyl methyl ester , ethyl linoleic acid ; fifteen fatty acid components were isolated and identified , and the components with a relative content ≥5% were 14-methyl-pentadecanoic acid methyl ester , diisobutyl phthalate , octade- canoic acid methyl ester , [1S-(1α , 3Aβ , 4α , 8Aβ)]-Decahydro-4, 8, 8-trimethyl-9-methylene-1, 4-methylene octene-long folene . Experiments have shown that the advanced unsaturated fatty acids contained in chaenomeles speciosa exhibit sig- nificant pharmacological activities in reducing blood lipids , antioxidation , anti-inflammatory , and other aspects .
