Hydrodistillation of the fresh stem and leaf of Neolitsea kedahense Gamble, collected from Gunung Jerai, Malaysia followed by the GC-FID and GC-MS analysis revealed the detection of a total of 47 constituents of which 28 (86.4%) from the stem and 31 (96.4%) constituents from the leaf. δ-Cadinene (17.4%), 1-epi-cubenol (11.8%), cyperotundone (9.0%), cis-cadin-4-en-7-ol (7.7%), τ-cadinol (7.1%) and α-cadinol (7.1%) were the principle constituents in the stem oil, whereas β-caryophyllene (18.9%), bicyclogermacrene (18.6%) and trans-muurola-4(14),5-diene (9.8%) were the major constituents in the leaf oil. Among the identified constituents, three constituents namely 7-epi-α-selinene, junenol and cis-cadin-4-en-7-ol have not been found previously from Neolitsea oils. The stem and leaf oils were screened for their α-glucosidase inhibitory and antibacterial activities. Both oils displayed potential α-glucosidase inhibitory activity, while the stem oil possessed weak antibacterial activity against Bacillus subtilis.
对采自马来西亚吉辇山的 Kedah 新木姜子(Neolitsea kedahense Gamble)新鲜茎叶进行水蒸馏,随后进行气相色谱 - 火焰离子化检测(GC - FID)和气相色谱 - 质谱联用分析(GC - MS),结果显示共检测到 47 种成分,其中茎中有 28 种(86.4%),叶中有 31 种(96.4%)。δ-杜松烯(17.4%)、1-表古巴醇(11.8%)、香附子烯二酮(9.0%)、顺式-杜松-4-烯-7-醇(7.7%)、τ-杜松醇(7.1%)和α-杜松醇(7.1%)是茎油中的主要成分,而β-石竹烯(18.9%)、双环大根香叶烯(18.6%)和反式-穆罗-4(14),5-二烯(9.8%)是叶油中的主要成分。在已鉴定的成分中,7-表-α-芹子烯、珠树醇和顺式-杜松-4-烯-7-醇这三种成分此前在新木姜子属植物油中未曾发现。对茎油和叶油进行了α-葡萄糖苷酶抑制活性和抗菌活性筛选。两种油均表现出潜在的α-葡萄糖苷酶抑制活性,而茎油对枯草芽孢杆菌具有较弱的抗菌活性。
