Abstract

Leaves of Afraegle paniculata were collected from southwestern Nigeria and hydrodistilled to give an essential oil in 0.56 % yield. The essential oil was analyzed by gas chromatography-mass spectrometry and was dominated by sesquiterpenoids. The major components in the leaf essential oil were α-copaene (20.1 %), (E)-caryophyllene (15.8 %), δ-cadinene (17.7 %) and caryophyllene oxide (18.4 %). The essential oil was screened for antimicrobial effects but showed only marginal activity (MIC ≥ 156 μg/mL).

摘要

从尼日利亚西南部收集pan曲花的叶子，并进行水蒸馏，以0.56％的收率得到精油。通过气相色谱-质谱法分析精油，并以倍半萜类化合物为主。叶片精油中的主要成分为α-可卡因（20.1％），（E）-石竹烯（15.8％），δ-卡丁烯（17.7％）和石竹烯氧化物（18.4％）。筛选了精油的抗微生物作用，但仅显示边缘活性（MIC≥156μg/ mL）。
