Comparison of Essential Oil Components and <i>In Vitro</i> Antioxidant Activity of <i>Zanthoxylum nitidum</i> from Different Parts.

ABSTRACT: Zanthoxylum nitidum is a traditional Chinese herb, but limited information is available concerning its composition and pharmacological effects of essential oils from different parts of Z. nitidum. This study examined the composition and in vitro antioxidant activity of essential oils from different parts of Z. nitidum in China. The results indicate that the highest essential oil extraction rate was obtained from the pericarps (0.42%), primarily consisting of caryophyllene oxide (15.33%), nerolidol 2 (14.03%), and spathulenol (9.64%). This was followed by the leaves (0.21%), stems (0.09%), and roots (0.05%), with the highest content in their essential oils being caryophyllene (27.03%), cadina-1(10),4-diene (25.76%), and benzyl benzoate (17.11%), respectively.
