摘　　要：目的寻找鉴别姜天麻的特征及方法。方法按《中华人民共和国药典》鉴别通则对模拟制备的姜天麻进行系统实验观察,选出主要鉴别特征及鉴别方法,据此试行鉴别两批"姜天麻"饮片,验证该特征及鉴别方法的可靠性。结果性状主要特征为有时具姜样气味;显微主要特征为多糖类团块、厚壁细胞、薄壁细胞、草酸钙针晶束及姜的淀粉粒、梯纹导管、纤维、油细胞等;碘试液反应呈紫棕、红紫色。以之为指标,正确鉴别出两批饮片为掺伪品。结论性状、显微、理化(碘试液反应)等鉴别法可正确鉴别姜天麻的真伪及掺伪,简便易行。Objective To search for characteristics and methods of identifying the prepared gastrodia （stir-backed with ginger juice）. Methods The prepared gastrodia was systemically made in lab observed according to the methods of the Chinese Pharmacopoeia.

The reliability of the characteristics and methods was tested and verified by identifying two batches prepared gastrodia products. Results The main macroscopic characters： It had the scent of ginger sometimes. The main characteristics of microscopic.. Lots of polysaccharides, thick-waUed cells, thinner-waUed cells, raphides and substances from ginger, such as starch grains, scalarfform vessels, fibers, oil cells, and so on.
