The surface is dark yellow, rough, with shriveled texture and obvious links, and there are circular branch marks and fibrous root marks. Solid, not easy to break, brown-yellow to golden-yellow cross-section, horny, waxy luster, obvious ring pattern of inner cortex, and dotted vascular bundles. The smell is unique, and the taste is bitter and pungent.
17.4 Identification (1) Cross section of this product: epidermal cells are flat and thin. The cortex is broad and has vascular bundles with leaves; There are 6 ~ 8 rows of cork cells near the epidermis, which are flat; The Kjeldahl point of endodermis cells is obvious. The stele sheath is1~ 2 rows of parenchyma cells; The vascular bundle is tough outside, scattered, more near the pericycle sheath, and gradually decreases inward. The parenchyma cells contain oil droplets, starch granules and red-brown pigment.
(2) Take 0.2g of this product powder, add 20ml of anhydrous ethanol, shake it, leave it for 30min, filter it, evaporate the filtrate, and add 2ml of anhydrous ethanol to dissolve the residue, which will be used as the test solution. Another control medicinal material, Curcuma longa, was prepared into control medicinal material solution by the same method.
