摘要
为比较不同白木香(Aquilaria Sinensis)种质所产沉香精油气味成分和生物活性差异,以易结香种质所产奇楠沉香和传统种质所产沉香为原料,采用水浸煮蒸馏法提取精油;采用气相色谱-质谱联用技术(GC-MS)和顶空-固相微萃取-气相色谱-质谱联用技术(HS-SPME-GC-MS)分析2类沉香精油成分组成;结合嗅闻分析,筛选精油气味成分,确认其属性;评价2类沉香精油抑菌和抗炎活性。结果表明,2类沉香精油均以倍半萜类化合物为主,含有少量芳香族化合物;仅在奇楠沉香精油(QNAEO)中检测出2-(2-苯乙基)色酮,传统沉香精油(OAEO)中苄基丙酮相对含量较高。2类沉香精油气味均由倍半萜类、芳香族和脂肪族化合物组成。2类沉香精油均以花香、木和甜味为主要特征气味;QNAEO清新味较强,OAEO谷物味较强。OAEO抑制金黄色葡萄球菌(Staphylococcus aureus)活性略高于QNAEO;QNAEO细胞毒性略低于OAEO,抗炎活性较高。
In order to compare differences among odorants and bioactivities of essential oils from different germplasms of Aquilaria sinensis,essential oils were extracted via hydrodistillation from Qi-Nan agarwood(produced from easily resin-forming germplasm)and ordinary agarwood(produced from common germplasm).Components of two agarwood essential oils were analyzed by GC-MS and HS-SPME-GC-MS.Odorants were screened and their properties were identified by olfactory analysis.Anti-bacterial and anti-inflammatory activities of two agarwood essential oils were evaluated.Results showed that sesquiterpene compounds were predominant components in two agarwood essential oils,with minor aromatic compounds.2-(2-phenylethyl)chromone was only detected in Qi-Nan agarwood essential oil(QNAEO)while relative content of benzylacetone was higher in ordinary agarwood essential oil(OAEO).Odorants of two agarwood essential oils were composed of sesquiterpene,aromatic and aliphatic compounds.Odorants of two agarwood essential oils were mainly characterized by floral,woody and sweet odors.QNAEO had stronger fresh odor and OAEO had stronger grain odor.OAEO exhibited slightly higher anti-bacterial activity against Staphylococcus aureus than QNAEO.QNAEO showed higher antiinflammatory activity and slightly less cytotoxicity than OAEO.
