Abstract

The essential oils of the aerial parts of Ocimum basilicum Linn. var. pilosum (Willd.) Benth., an endemic medicinal plant growing in China, was obtained by hydrodistillation and analysed by GC-MS. Fifteen compounds, representing 74.19% of the total oil were identified. The main components were as follows: linalool (29.68%), (Z)-cinnamic acid methyl ester (21.49%), cyclohexene (4.41%), α- cadinol (3.99%), 2,4-diisopropenyl-1-methyl-1-vinylcyclohexane (2.27%), 3,5-pyridine-dicarboxylic acid, 2,6-dimethyl-diethyl ester (2.01%), β-cubebene (1.97%), guaia-1(10),11-diene (1.58%), cadinene (1.41%) (E)-cinnamic acid methyl ester (1.36%) and β-guaiene (1.30%). The essential oils showed significant antifungal activity against some plant pathogenic fungi.

Highlights

  • It is estimated that almost 30% of planted crops are lost due to attack of feeding insects, spoilage or disease [1]

  • The essential oils of the aerial parts of Ocimum basilicum Linn. var. pilosum (Willd.) Benth., an endemic medicinal plant growing in China, was obtained by hydrodistillation and analysed by GC-MS

  • Molecules 2009, 14 supply to a growing world population, in this era of increased concern about the safety of chemicals used in plant protection, natural methods of plant protection and natural preservatives are receiving increased attention, so nowadays, more and more attention is being paid to the use of natural products and their derivatives in terms of environment-friendly materials, negligible persistent residues good selectivity, and so on
