Abstract

The chemical compositions of the essential oils obtained from six tree parts of Chrysophyllum albidum (Sapotaceae) were extracted by hydrodistillation and analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). A total of 65, 33, 45, 21, 25 and 18 compounds, representing 79.49%, 100%, 90.81%, 98.43%, 96.62% and 98.37% of the total oil, were identified in the fruit bark, root bark, stem bark, seed bark, leaf and seed, respectively. The dominant compounds in the essential oils in six tree parts were m-xylene (66.7%; seed), p-xylene (21.4%; seed bark), α-farnesene (38.1%; leaf), hexadecanoic acid (14.7%; stem bark), m-xylene (53.1%; root bark) and hexadecanoic acid (12.7%; fruit bark). The essential oils were evaluated for their antibacterial, antioxidant and insecticidal activities using Alamar blue assay, DPPH radical scavenging activity and contact toxicity test, respectively. The oils displayed moderate antibacterial potentials to some tested organisms and low radical scavenging activity to DPPH. Rhyzopertha dominica was susceptible to C. albidum stem bark essential oil only.

金菊挥发油的化学和生物学评价

采用水蒸气蒸馏法提取金菊(Chrysophyllum albidum, sapotacae) 6个树种的精油，采用气相色谱(GC)和气相色谱-质谱联用(GC- ms)对其化学成分进行分析。从果皮、根皮、茎皮、籽皮、叶和种子中分别鉴定出65、33、45、21、25和18个化合物，分别占总油的79.49%、100%、90.81%、98.43%、96.62%和98.37%。6个树种挥发油中主要化合物为间二甲苯(66.7%);种子)，对二甲苯(21.4%;α-法尼烯(38.1%;叶)，十六烷酸(14.7%;茎皮)，间二甲苯(53.1%;根皮)和十六烷酸(12.7%;水果皮)。采用Alamar蓝试验、DPPH自由基清除试验和接触毒性试验，分别评价其抗菌、抗氧化和杀虫活性。该精油对部分受试生物具有中等抑菌活性，对DPPH具有较低的自由基清除活性。鸦尾草对合欢茎皮精油仅敏感。
