摘　　要：分别采用扫描电镜和紫外光谱法对地肤子、藜、小藜和扫帚菜四种药材进行了比较鉴别。结果表明:扫描电镜下四种药材的胞果、毛茸、气孔和种子形态特征有较为明显的区别;紫外光谱扫描结果表明地肤子和扫帚菜无明显区别,但与藜和小藜之间有显著区别。Scanning electron microscope (SEM) and UV spectrum methods were used to identify Kochia scoparia and its substitutes , including the fruits of Chenopodium album, Chenopodium serotinum and Kochia scoparia ( L. ) Schrad. f. trichophila Schirz. et Thell. . The results showed that kochia scoparia differed from the substitutes in utride, trichome, stoma and shape of seed under SEM. The UV spectrum of Kochia scoparia was similar to that of Kochia scoparia f. trichophila , but significantly different from that of Chenopodium album and Chenopodium serotinum.
