摘要
采用水蒸气蒸馏法提取高良姜花和果实的挥发油,采用GC-MS法测定其化学成分,并采用琼脂滤纸片法测定其抗菌活性。结果表明,高良姜新鲜的花和果实中的挥发油含量分别为0.003%和0.209%;花挥发油中的主要成分为Caryophyllene oxide(40.63%)和β-caryophyllene(11.14%),果实挥发油中的主要成分为α-cadinol(41.20%)和τ-cadinol(22.88%);花和果实的挥发油对金黄色葡萄球菌和耐甲氧西林金黄色葡萄球菌的生长均有一定的抑制活性。
Flowers and fruits of Alpinia officinarum were extracted by hydrodistillation method to get the essential oil, whose chemical constituents were analyzed by GC-MS, and whose antimicrobial activities were assayed by filter disks. The results showed that contents of essential oil in fresh flowers and fruits of A. officinarum were 0.003% and 0.209%, respectively. The main constituents in its flowers were caryophyllene oxide （40.63%） and 3-caryophyllene （11.14%）, while those in its fruits were -cadinol （41.20%） and cadinol （22.88%）. The essential oils from flowers and fruits of A. officinarum both had inhibitory effect on the growth of Staphyloccocus aureus and methicillin-resistant S. aureus （MASR）.
