中药材橘红收载在1990年版《中国药典》一部336页、1995年版一部332页上。[鉴别](1)项为粉末显微鉴别,描述了橘红粉末的两个显微特征:一是果皮表皮细胞,二是油室碎片。为配合1990年版《中国药典》而编绘的《常用中药材组织粉末图解》(赵达文主编)一书中,也只是描绘了橘红的这两个特征。笔者通过对橘红的显微观察发现,橘红还有一个显著的显微特征,就是果皮表皮细胞以下的几列薄壁细胞中成片含有草酸钙方晶。
The oranges of Chinese herbal medicines were collected on the 336 pages of the 1990 Chinese Pharmacopoeia and 332 pages of the 1995 edition. [Identification] (1) The microscopic identification of the powder describes two microscopic characteristics of the orange powder: one is epidermal cells of the skin and the other is oil cell fragments. The book “Diagram of Commonly Used Chinese Herbal Medicine Powder” (edited by Zhao Dawen) compiled for the 1990 edition of the “Chinese Pharmacopoeia” only describes these two characteristics of orange. By microscopic observation of orange, the author found that there is a significant microscopic feature of orange, which is a small piece of parenchyma cells below the epidermis of the pericarp containing pieces of calcium oxalate crystals.
