ZEF, ZBF, and ZWF are extracts from Zhangping Narcissus tea cake by ethyl acetate, n-butanol, and water, respectively. All the main chemical compositions are calculated based on the weight of extracts. ND means not detected. ^a–c Different letters mean significant difference (P<0.05). Data are expressed as mean±SD (n=3)
