Basil (Ocimum basilicum L.), as an aromatic and medicinal plant, exhibits numerous of genotypes that have various applications in food and pharmaceutical industries. Thus, chemical composition is an important parameter for assessing the quality of basil. Hence, twelve European basil genotypes were cultivated under the same conditions, and isolated essential oils and methanol extracts were subjected to detailed chemical analyses and testing their biological activities. According to the analysis of the volatiles, all genotypes belong to linalool chemotype, and they were clustered into two groups. Rosmarinic acid was found to be the major phenylpropanoid, following with luteoin, kaempherol, and rutin. Principal component analysis of phenolic compounds indicated segregation of genotypes in two distinct groups. Biological activities of the isolated extracts were correlated with the concentrations of the actives, and it was found that naringenin, luteolin, and kaempherol are the main carriers of antioxidant activity, while the levels of linalool correlated with tyrosinase inhibition activity. Adversely, methyl chavicol showed negative correlations with both assays. Finally, it was found that Czech genotypes (Litra and Chladek), as well as Dutch (Bush) and Italian (Fino Verde Compatto) possess significant amounts of terpenoid linalool, together with flavonoids luteolin, naringenin, and kaempherol, and therefore, have strong biological activities required for their use in food and cosmetic industries.

罗勒（罗勒罗勒L.），作为芳香植物和药用植物，展现出许多在食品和制药工业中都有各种应用的基因型。因此，化学组成是评估罗勒品质的重要参数。因此，在相同条件下培养了12种欧洲罗勒基因型，并对分离出的精油和甲醇提取物进行了详细的化学分析并测试了其生物活性。根据挥发物的分析，所有基因型均属于芳樟醇化学型，并被分为两组。迷迭香酸是主要的苯丙烷，其次是黄体素，山梨醇和芦丁。酚类化合物的主成分分析表明基因型在两个不同的组中分离。分离出的提取物的生物活性与活性物质的浓度相关，并且发现柚皮苷，木犀草素和山梨醇是抗氧化活性的主要载体，而芳樟醇的水平与酪氨酸酶抑制活性相关。不利的是，甲基查维醇与两种测定均呈负相关。最后，我们发现捷克基因型（Litra和Chladek），荷兰人（布什）和意大利人（Fino Verde Compatto）拥有大量的萜烯类芳樟醇，以及黄酮类木犀草素，柚皮素和kaempherol，因此具有较强的抗性。它们在食品和化妆品工业中使用所需的生物活性。而芳樟醇的水平与酪氨酸酶抑制活性有关。不利的是，甲基查维醇与两种测定均呈负相关。最后，我们发现捷克基因型（Litra和Chladek），荷兰人（布什）和意大利人（Fino Verde Compatto）拥有大量的萜烯类芳樟醇，以及黄酮类木犀草素，柚皮素和kaempherol，因此具有较强的抗性。它们在食品和化妆品工业中使用所需的生物活性。而芳樟醇的水平与酪氨酸酶抑制活性有关。不利的是，甲基查维醇与两种测定均显示负相关。最后，我们发现捷克基因型（Litra和Chladek），荷兰人（布什）和意大利人（Fino Verde Compatto）拥有大量的萜烯类芳樟醇，以及黄酮类木犀草素，柚皮素和kaempherol，因此具有较强的抗性。它们在食品和化妆品工业中使用所需的生物活性。
