西洋参与人参的简易鉴别方法

Difference and Simple Identification between Panax quinquefolium L. and Radix Ginseng

目的防止以人参（生晒参、白参）伪充西洋参使用，避免发生副反应。方法利用性状鉴别和荧光鉴别区分人参与西洋参。结果在遮光条件下用紫外光灯（254nm）观察荧光色泽，西洋参的断面木质部显蓝紫色荧光，生晒参的断面木质部显蓝色荧光，白参的断面木质部显亮蓝色荧光。结论利用性状鉴别法和荧光法鉴别人参与西洋参，操作方法简便，易于推广。

Objective To prevent phenomena of using Radix Ginseng （dry Radix Ginseng and white sugar Radix Ginseng） instead of Panax quinquefolium L. and to avoid the occurrence of side effects. Methods Panax quinquefolium L and Radix Ginseng were distinguished by their characters and fluorescence identification. Results Fluorescence color was observed by using ultraviolet lamp （254 nm） under the light-shading condition. The hadromestome of Panax quinquefolium L showed amethyst fluorescence, the dry Radix Ginseng showed blue fluorescence, and the white sugar Radix Ginseng showed bright blue fluorescence. Conclusion Fluorometric method can be used to identify Panax quinquefolium L and Radix Ginseng. This method is simple and easy for spread.
