3. Identification method of exocarpium Citri Grandis
(1) The powder of this product is dark green to brown. The parenchyma cells of mesocarp are irregular in shape, and the walls are unevenly thickened, and some of them are beaded or extremely thick in corners. Epidermal cells in pericarp are polygonal, square or rectangular in surface, with thickened vertical wall, round stomata with diameter of18 ~ 31μ m, and 5 ~ 7 accessory cells, which are thickened by cuticle and radial wall outside. Occasionally, broken non-glandular hairs are seen, with more than a dozen broken cells, the widest part of which is about 33μm in diameter, with wall warts or smooth outer wall and rough inner wall, and the cell cavity contains yellowish or brown granules. Square crystals of calcium oxalate exist in thin-walled cells of mesocarp in sheets or rows, which are polygonal, rhombic, prismatic, rectangular or irregular in shape, with a diameter of1~ 32 μ m and a length of 5 ~ 40 μ m. Catheters are threaded and reticulated. Occasionally, stone cells and fibers are seen.
(2) Take the product powder 1g, add methanol 10ml, heat and reflux for 20min, let it cool, filter, take the filtrate 1ml, add about 5mg of potassium tetrahydroborate, shake well, and add a few drops of hydrochloric acid, that is, it will appear fuchsia or purplish red.
(3) Take the filtrate under [Identification] (2) as the test solution. Another naringin reference substance was added with methanol to prepare a solution containing 0.4mg 1ml as the reference substance solution. According to the test of thin-layer chromatography (Appendix ⅵ b), absorb each 10μl of the above two solutions, respectively spot them on the same silica gel G thin-layer plate, use the upper solution of ethyl acetate-formic acid-water (10:2:3) as the developing agent, unfold, take it out, air dry it, spray the aluminum trichloride test solution, and place it in an ultraviolet lamp (330). In the chromatogram of the test sample, fluorescent spots with the same color appear at the positions corresponding to the chromatogram of the reference sample.
