Composition of ginger oil prepared from fresh ginger rhizomes, Zingiber officinale Roscoe (Zingiberaceae) was determined by gas chromatography (GC) and GC-mass spectrometric techniques. The main sesquiterpene hydrocarbons identified were alpha-zingiberene (27-30%), alpha-curcumene (8-9%), beta-sesquiphellandrene (4.8%). and bisabolene (3.2%). The function of zingiberene and curcumene as insecticides, repellents, and insect feeding deterrents has been previously reported. Other plant species having similar constituents might be found. Leaves of six wild tomato accessions of Lycopersicon hirsutum f. glabratum (Mull); three accessions of L. hirsutum f. typicum (Humb & Bonpl.); two accessions of L. pennellii Corr. (D'Arcy); one accession of L. pimpinellifolium; and one commercial tomato L. esculentumm cv. Fabulous were analyzed. Analysis of L. hirsutum f. typicum (Solanaceae) accessions indicated the presence of zingiberene, curcumene, and other lipophilic secondary metabolites in the leaves of two accessions (PI-127826 and PI-127827). An average three month old wild tomato plant of accessions PI-127826 and PI-127827 provided 1.93 and 1.30 kg fresh leaves (averaging about 38,307 and 28,130 cm2 exposed leaf surface area, respectively) and produced 19.3 and 10.1 g of zingiberene and curcumene (PI-127826) and 17.2 and 1.8 g of zingiberene and curcumene (PI-127827), respectively. Leaf extracts of the wild tomato L. hirsutum f. typicum (accessions PI-127826 and PI-127827) can be used as a biorational source of zingiberene and curcumene.
采用气相色谱（GC）和GC-质谱技术测定了由新鲜姜根茎（姜科植物姜，学名Zingiber officinale Roscoe）制备的姜油成分。鉴定出的主要倍半萜烃类成分有α-姜烯（27 - 30%）、α-姜黄烯（8 - 9%）、β-倍半水芹烯（4.8%）和甜没药烯（3.2%）。此前已有报道称姜烯和姜黄烯具有杀虫剂、驱避剂及昆虫取食抑制剂的功能。可能会发现其他含有类似成分的植物物种。对六种野生番茄材料进行了分析，包括多毛番茄光滑变种（Lycopersicon hirsutum f. glabratum (Mull)）的六个材料、多毛番茄典型变种（L. hirsutum f. typicum (Humb & Bonpl.)）的三个材料、彭氏番茄（L. pennellii Corr. (D'Arcy)）的两个材料、醋栗番茄（L. pimpinellifolium）的一个材料以及一个商业番茄品种“Fabulous”（L. esculentumm cv. Fabulous）。对多毛番茄典型变种（茄科）材料的分析表明，在两个材料（PI - 127826和PI - 127827）的叶片中存在姜烯、姜黄烯及其他亲脂性次生代谢产物。PI - 127826和PI - 127827这两个材料中平均三个月大的野生番茄植株分别提供了1.93千克和1.30千克鲜叶（暴露叶表面积平均分别约为38307平方厘米和28130平方厘米），并分别产生了19.3克和10.1克的姜烯和姜黄烯（PI - 127826）以及17.2克和1.8克的姜烯和姜黄烯（PI - 127827）。多毛番茄典型变种（PI - 127826和PI - 127827材料）的叶提取物可作为姜烯和姜黄烯的生物合理来源。
