Abstract

ABSTRACT This study aimed at chemical variability of flower essential oils of 10 well-known cultivars of Paeonia × suffruticosa Andr. The essential oil yields ranged as 0.19–0.67% (w/w). The chemical compositions varied with cultivars. ‘Xueying Taohua’ essential oil had predominance of citronellol (56.4%). ‘Guifei Chacui’ essential oil was rich in citronellol (35.9%) and phloroglucinol trimethyl ether (25.3%). ‘Sheng Gejin’ and ‘Yuhou Fengguang’ essential oils were rich in phloroglucinol trimethyl ether (36.5%, 26.8%). ‘Yinhong Qiaodui’ essential oil contained geraniol + nerol (23.9%). Those from the other five cultivars did not present typical chemotypes. Nevertheless several compounds were noted, mainly germacrene D, heptadeca-6,9-diene, (Z)-hex-3-en-1-ol and linalool oxide (furan). ‘Luhe Hong’ essential oil contained the most unique components, including α-cadinol, τ-muurolol and δ-cadinene. Lack of phenylethyl alcohol was noticeable in some essential oil samples as compared with hydrolate extracts investigated previously. Multivariate analyses revealed four distinct clusters from all the essential oil samples.

十个著名芍药品种花精油的化学变异

摘要:本研究对10个知名芍药品种丹参花精油的化学变异进行了研究。精油得率为0.19 ~ 0.67% (w/w)。化学成分因品种而异。雪樱桃花精油中香茅醇含量最高(56.4%);桂妃茶翠精油中含有丰富的香茅醇(35.9%)和间苯三酚三甲基醚(25.3%)。“生歌金”和“雨后风光”精油中间苯三酚三甲基醚含量较高(分别为36.5%和26.8%)。银红巧兑精油中含有香叶醇+橙醇(23.9%)。其他5个品种均未表现出典型的化学型。尽管如此，还是发现了一些化合物，主要是烯丙烯D、十六烷基-6,9-二烯、(Z)-己-3-烯-1-醇和氧化芳樟醇(呋喃)。“鹿河红”精油中含有α-二羟基苯酚、τ-穆罗尔和δ-二羟基苯胺等最独特的化学成分。与先前研究的水合提取物相比，在一些精油样品中明显缺乏苯乙醇。多变量分析显示所有精油样品中有四个不同的聚类。

期刊介绍： Journal of Essential Oil Research ( JEOR) is the major forum for the publication of essential oil research and analysis. Each issue includes studies performed on the chemical composition of some of the 20,000 aromatic plants known in the plant kingdom. JEOR is devoted entirely to all phases of research from every corner of the world by the experts in their field. JEOR''s main areas of focus include: -Analytical chemistry- Biological activity- Biotechnology- Chemical composition- Chemical synthesis- Chemosystematics- Microbiological activity- Plant biochemistry/biosynthesis- Toxicology. Published six times per year, JEOR provides articles on the aromatic principles of a plant or its isolates and are directed toward furthering our readers'' knowledge of the aromatic plant and animal kingdoms.
