Abstract: In order to study the quantity and quality difference of patchouli essential oils with singlecropping and intercropping with Hevea brasiliensis,the patchouli essential oils were extracted by steam distillation.Then the chemical composition was analyzed by GC-MS.The yields of patchouli essential oils from singlecropping and intercropping with Hevea brasiliensis were 1.77% and 2.09%.The chemical composition of patchouli essential oils with different cropping mode had little difference,and main compounds were δ-guaiene,patchouli alcohol,α-guajene,β-patchoulene,α-patchoulen,etc.The difference of patchouli essential oils with different cropping mode were the amount of same chemical composition,such as boldenon,patchouli alcohol,δ-guaiene,β-patchoulene and α-guajene,and the variance ratios of contents ranged from 1.18% to 4.60%.2-3 year-age of Hevea brasiliensis grove was a suitable cultivation environment for Pogostemon cablin planting,and the patchouli essential oil from intercropping with Hevea brasiliensis had little difference with patchouli essential oil from singlecropping.Intercropping with Hevea brasiliensis was a good method for Pogostemon cablin planting,the farmer could got economic benefit and ecological benefit.

Key words: intercropping with rubber tree, singlecropping, Pogostemon cablin (Blanco) Benth, essential oil, GC-MS
