研究了肯尼亚不同产地罗勒（OcimumbasilicumL.）和罗勒（OcimumgratissimumL.）精油的化学成分及其对轮枝镰刀菌（Fusariumverticillioides）侵染和伏马菌素产生的抑制作用。雅达的花尖和叶中主要含有樟脑（分别为32.6%和31.0%）和芳樟醇（分别为28.2%和29.3%）。丁香酚是两种植物叶油的主要成分（分别为95.5%和70.1%）。花顶的油中丁香酚明显较少。Yatta植物油的主要成分为Z-β-罗勒烯（34.1%），两种植物油均具有一定的抗真菌活性。不同产地的罗勒和Gratissimum植物油的化学成分、抗真菌活性、清除自由基能力和抗真菌毒力均存在差异。这些特性归因于酚类化合物丁香酚工业相关性这份手稿给出了肯尼亚两种罗勒属植物即罗勒罗勒L.和罗勒（Ocimum gratissimum L.）这项工作表明，这些植物在该国的不同地点都有化学变种。重要的是，在一种化学变种O basilicum中存在非常高含量的芳樟醇，而在另一种化学变种中主要是香叶醛和橙花醛。第三种变种含有几乎等量的樟脑和芳樟醇。前两种含有大量的芳樟醇，香叶醛和橙花醛可在农艺学研究后培养，以提供香料、肥皂或食品工业中有用的精油，而含有樟脑和芳樟醇的精油可用于医药。含有大量丁香酚的gratissimum可以作为丁香的良好替代品，丁香仅在东非的几个岛屿上生长得最好。丁香油由于其高丁香酚含量而具有许多生物活性，包括本工作中所证明的那些，在医药和商业领域有着广泛的应用前景，需要对这些植物进行更多的研究，特别是在草药的栽培和商业开发方面（C）2009爱思唯尔有限公司版权所有
This work investigated the constituents and the efficacy against Fusarium verticillioides infection and fumonisin production of essential oils of Ocimum basilicum L and Ocimum gratissimum L from different locations in Kenya.The oil of leaves and flowering tops of O basilicum from Sagana contained mainly linalool (95%). The flowering tops and leaves from Yatta contained mainly camphor (32 6 and 31 0%, respectively) and linalool (28 2 and 293, respectively) Eugenol was the main constituent in the oil of O gratissimum leaves from both Sagana (95.5%) and Yatta (70.1%). The oil of the flowering tops had significantly less eugenol. The main component of the oil of flowering tops from Yatta was Z-beta-ocimene (34 1%) Oil from both species had some antifungal activity The oils of O basilicum and O gratissimum from different locations showed chemical variation, antifungal activity, free radical scavenging capacity and antimycotoxicogenic property. These properties are attributed to the phenolic compound eugenolIndustrial relevance This manuscript gives the chemical composition and some biological effects of essential oil of two Ocimum species in Kenya namely Ocimum basilicum L. and Ocimum gratissimum L. The work reveals that there are chemovarieties of these plants in different locations in the country Of significance is the presence of very high amounts of linalool in one chemovariety of O basilicum while geranial and neral are major in another The third variety contains almost equal amounts of camphor and linalool The first two containing high quantities of linalool, geranial and neral could be cultivated after agronomic studies to provide essential oils useful in perfumery, soap or food industry while that containing camphor and linalool may find use in medicineProper seed selection and good agricultural practice for O. gratissimum containing high amount of eugenol could serve as good substitute for cloves which grows best only in a few islands in East Africa Clove oil due to its high eugenol content has many biological activities including those demonstrated in the present work, and many applications in medicine and commercial world.There is need for more research on these plants especially on cultivation and commercial exploitation of the herbs (C) 2009 Elsevier Ltd All rights reserved
