晶纤维是中药显微鉴别的重要依据之一。77年版《中国药典》记载,在206种有组织的中成药中,有182种须进行显微鉴别。由于不同药材纤维的形态、大小、颜色、木化程度均不相同;晶体的成分,大小形态,在纤维上着生部位各异,以及含晶细胞壁的厚薄、木化程 Crystal fiber is one of the important basis for microscopic identification of traditional Chinese medicine. According to the “Chinese Pharmacopoeia” published in the 77th edition, 182 out of 206 organized Chinese patent medicines are subject to microscopic identification. Because the shape, size, color, and degree of woodization of different medicinal fibers are all different, the composition, size and shape of crystals, the locations of different parts on the fibers, and the thickness and crystallization of cell walls
