Seed coat thin and brittle; cotyledons 2, yellowish-white, oily. Odour, slight; taste, mild, slightly bitter and pungent.

鉴别 Identification

(1) 本品粉末淡黄色至棕黄色。种皮栅状细胞成片,淡黄色、橙黄色、黄棕色或红棕色,表面观呈多角形或长多角形,直径约至15μm,常与种皮大形下皮细胞重叠,可见类多角形或长多角形暗影。内胚乳细胞表面观呈类多角形,含糊粉粒和脂肪油滴。子叶细胞无色或淡灰绿色,壁薄,含糊粉粒及脂肪油滴。

The powder is pale yellow to brownish-yellow. The epidermal cells of the seed coat are arranged in rows, pale yellow, orange-yellow, yellow-brown, or reddish-brown. The surface appears polygonal or elongated polygonal, with a diameter of about 15μm. It often overlaps with the large subepidermal cells of the seed coat, and polygonal or elongated polygonal shadows can be seen. The surface of the endosperm cells appears polygonal, with starch grains and oil droplets. The cotyledon cells are colorless or pale grayish-green, with thin walls, starch grains, and oil droplets.

(2) 取本品粉末1g,加乙醚30ml,加热回流1小时,弃去乙醚液,药渣挥干,加甲醇20ml,加热回流1小时,滤过,滤液蒸干,残渣加甲醇2ml使溶解,作为供试品溶液。另取莱菔子对照药材1g,同法制成对照药材溶液。再取芥子碱硫氰酸盐对照品,加甲醇制成每1ml含1mg的溶液,作为对照品溶液。照薄层色谱法(通则0502)试验,吸取上述三种溶液各3~5μl,分别点于同一硅胶G薄层板上,以乙酸乙酯-甲酸-水(10∶2∶3)的上层溶液为展开剂,展开,取出,晾干,置紫外光灯(365nm)下检视。供试品色谱中,在与对照药材色谱和对照品色谱相应的位置上,显相同颜色的荧光斑点;喷以1%香草醛的10%硫酸乙醇溶液,加热至斑点显色清晰,显相同颜色的斑点。

(2) Take 1g of this product powder, add 30ml of ether, heating reflux for 1 hour, discard the ether solution, the residue volatile dry, add 20ml of methanol, heating reflux for 1 hour, filtration, filtrate evaporation, residue add 2ml of methanol to make dissolved, as a test solution. Take 1g of control herb of Lycopodium album, and make the solution of control herb by the same method. Then take mustard alkali thiocyanate control, add methanol to make a solution containing 1mg per 1ml, as a control solution. According to the thin-layer chromatography (General rule 0502) test, absorb the above three solutions of 3 ~ 5μl, respectively, point in the same silica gel G thin-layer plate, ethyl acetate - formic acid - water (10:2:3) of the upper layer of the solution as the unfolding agent, unfolding, take out, drying, and placed in the ultraviolet lamp (365nm) under the examination. In the chromatogram of the test article, in the corresponding position with the chromatogram of the control herb and the chromatogram of the control article, the fluorescent spots of the same colour were shown; 10% ethanol sulphate solution with 1% vanillin was sprayed, and heated until the spots were clear and showed the spots of the same colour.
