Abstract

Essential oils of Duguetia lanceolata barks, obtained at 2 (T2) and 4 h (T4), were identified by gas chromatography and gas chromatography/mass spectrometry. β-elemene (12.7 and 14.9%), caryophyllene oxide (12.4 and 10.7%) and β-selinene (8.4 and 10.4%) were the most abundant components in T2 and T4, respectively. The essential oils inhibited the growth of Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli and Candida albicans. The essential oils were cytotoxic against brine shrimp. The extraction time influenced the chemical composition and biological activities of essential oils obtained from the barks of D. lanceolata.

摘要

狭叶杜茎山树皮的精油在 2 小时(T2)和 4 小时(T4)时分别提取,并用气相色谱法和气相色谱/质谱法进行了鉴定。β-榄香烯(12.7%和 14.9%)、石竹烯氧化物(12.4%和 10.7%)和β-芹子烯(8.4%和 10.4%)分别是 T2 和 T4 中含量最丰富的成分。精油抑制了金黄色葡萄球菌、化脓性链球菌、大肠杆菌和白色念珠菌的生长。精油对卤虫具有细胞毒性。提取时间影响从狭叶杜茎山树皮中提取的精油的化学成分和生物活性。
