The results showed that leaves are abundant of cis-3-hexenyl benzoate (10.75%), benzyl benzoate (8.16%) and caryophyllene oxide (8.12%). The main compounds of stems were benzyl benzoate (21.92%), E-nuciferol (11.58%) and dibutyl phthalate (7.08%), while major components of flowers were benzyl benzoate (9.99%), caryophyllene oxide (8.14%) and E-nuciferol (8.13%). The antioxidant activities of methanol extract were evaluated by DPPH and β-carotene/linoleic acid assays. The results showed that in both methods, leaves had stronger antioxidant activity than other organs.</p> ER -
