AbstractChemical compositions of V. negundo and V. trifolia essential oils and their anatomical study were determined. The GC-FID and GC_MS analysis of essential oils resulted in the identification of 14 and 18 components were identified from the leaf oils of V. negundo (92.8%) and V. trifolia (91.5%), respectively. The results revealed that the essential oils are made up principally of _-elemene (43.1%), spathulenol (9.8%) for V. negundo, while viridiflorol (42.3%) and _-caryophyllene (21.7%) for V. trifolia. Meanwhile, for anatomical part, the oil gland has been found in the lamina, midrib and petiole of all essential oils.
