Identification
(1) Cross section of this product: the cork layer has 2 to 10 rows of cells. The cortex is slightly wider and has a few secretory tracts. The vascular bundles are tough outside, arranged in a ring, and the cambium forms a ring. Secretory tracts are occasionally seen in the phloem. The xylem bundles are slightly arranged in a radial pattern of 2 to 4 strands, and some are arranged in a single row; the wood fibers often have 1 to 4 bundles, and some fiber bundles have larger woody thick-walled cells next to them. Centrally pithed. The parenchyma cells contain numerous calcium oxalate cluster crystals with a diameter of 17 to 70 μm and contain starch granules. The powder is yellow-white to yellow-brown. The wood fibers are in bundles, with a diameter of about 25 μm, a slightly thicker wall, and pits that are oblique and crack-shaped, and some cross in a herringbone shape. Calcium oxalate cluster crystals are common, with a diameter of 15 to 70 μm. The diameter of the trapezoidal, reticulated or edged pit vessels is 20 to 70 μm. Resin channel fragments are occasionally seen, containing yellow lumps. The cells of cork tissue fragments are polygonal, rectangular or irregular in shape, with thick walls. There are many starch granules, mostly single granules, approximately round in shape, about 10 μm in diameter, or gelatinized.
(2) Take 0.5g of this product powder, add 5ml of ethanol, shake for 5 minutes, filter, evaporate the filtrate to dryness, add dropwise chloroform solution saturated with antimony trioxide, and then evaporate to dryness, it will appear purple. red.
(3) Take 1g of this product powder, add 5 to 10 drops of water, mix well, add 10ml of water-saturated n-butanol solution, seal tightly, shake for about 10 minutes, leave to drain, and filter , the filtrate was evaporated to dryness, and 10 ml of a mixed solution of sulfuric acid and 30% ethanol (1→20) was added to the residue, heated to reflux for 2 hours; shake and extract with 20 ml of chloroform, separate the chloroform layer, wash with 10 ml of water, discard the washing liquid, and chloroform liquid Evaporate to dryness, add 1ml of methanol to the residue to dissolve, and use it as the test solution. Take another reference substance of oleanolic acid, ginsengdiol and ginsenotriol, add methanol respectively to make three solutions containing 2mg of oleanolic acid, 0.5mg each of ginsengdiol and ginsenotriol per 1ml, as the reference solution . According to the thin layer chromatography (Appendix VI B) test, take 5 μl of the above test solution and 1 μl of the reference solution, respectively, and place them on the same silica gel G thin layer plate, using benzene-ethyl acetate (1:1) as the solvent. Agent, unfold, take out, dry, spray with 10% sulfuric acid ethanol solution, and heat at 105°C until the spots appear clear. In the chromatogram of the test product, spots of the same color appear at the positions corresponding to the chromatogram of the reference substance.
The nature and flavor are sweet, slightly bitter and warm. Returns to the liver, spleen and lung meridians.
The main functions are nourishing and strengthening, dispersing blood stasis and relieving pain, stopping bleeding and eliminating phlegm. It is used for weakness after illness, cough with hemoptysis, cough with excessive phlegm, and injuries caused by falls.
