摘要:

用水蒸汽蒸馏法从野生糙苏籽中提取挥发油,利用气相色谱- 质谱联用技术对其挥发油中的化学成分进行分离和结构鉴定,运用气相色谱面积归一化法确定各个成分的相对百分含量。从糙苏籽的挥发油中鉴出56 种成分,其主要成分为α- 里哪醇(13.38%)、石竹烯氧化物(11.21%)、1- 辛烯-3- 醇(8.38%)、邻苯二甲酸二异丁酯(8.22%)、亚麻酸乙酯(6.21%)等。对糙苏籽的挥发油进行了抗氧化实验和抗菌实验,结果表明糙苏籽挥发油对·OH 有明显的清除作用,糙苏籽的挥发油对实验菌株均有明显的抑制和灭活作用,特别是大肠杆菌ATCC25922 株和肺炎球菌32201 株的抑制作用表现得更为显著。

Abstract:

Essential oil was extracted from wild Phlomis umbrosa seeds by steam distillation. The chemical components of the essential oil were separated and structurally identified using gas chromatography-mass spectrometry, and the relative contents of the components were determined through peak-area normalization method. The results showed that 56 components exist in essential oil, among which, the major components are α-linalool (13.38%), caryophyllene oxide (11.21%), 1-octen-3-ol (8.38%), phthalic acid, diisobutyl ester (8.22%) and linolenic acid, ethyl ester (6.21%), etc. The essential oil has obvious hydroxyl radical-scavenging effect, and inhibitory and inactivation effects against 8 standard bacteria, especially against Escherichia coli ATCC25922 and Pneumococcus 32201.

Key words: Phlomis umbrosa Turcz, essential oil, gas chromatography-mass spectrometry, antioxidant activity, antimicrobial activity
