Wolf poison identification
Identification
Character identification
【Storage and Storage】Dig roots in autumn, washed, freshly used or sliced and dried.
【Drug identification】 The root is swollen spindle, conical or long cylindrical, slightly curved, and some branches. There are remnants of stems on the head of the root, the surface is brown to tan, there are twisted longitudinal sulcus, transversely raised lenticels and lateral root marks, and white soft fibers are exposed at the detachment of the cork. Lightweight, tough, hard to break, the cross section is fibrous. The leather is white and the wood is light yellow. Gas slightly, taste slightly pungent.
Microscopic identification
Root cross-section: The cork layer consists of a dozen layers of yellow-brown cork cells; the cortex is thin, consisting of parenchyma cells; phloem ray cells are in 2-3 rows; most of the fiber bundles are in the cortex and phloem; The tangential extension is about 5-6 layers; the xylem is broad and the ducts are arranged radially. The parenchyma in the cortex and phloem contained many starch grains.
Powder characteristics
Yellow white. 1 Cork cells yellow-brown. 2 The phloem parenchyma cells are round or irregular and have cell gaps. 3 mesh catheter, occasionally bordered pit catheter, diameter 30-50μm. 4 fibers are colorless and 7-15μm wide. 5 starch grains are mostly units, round, helmet-shaped hat, striae are not obvious, umbilical point-like or crack-like, diameter 3-15μm.
Physical and chemical identification
Take this product coarse powder 5g, add ethanol 20ml, set on water bath reflux 1h. After filtration, the filtrate was concentrated to 5 ml for the following experiment:
(1) Take a test solution 1ml, add a little magnesium powder, a few drops of hydrochloric acid, set in a water bath and heat for a few minutes, place a magenta color.
(2) Take 1ml of the test solution, evaporate the evaporating dish and dry it, add 1ml of boric acid saturated acetone solution and 10% citric acid acetone test solution, continue to evaporate and observe under the ultraviolet light, and show yellow fluorescence.
(3) Take 1 drop of test solution on the filter paper, spray 1% aluminum trichloride ethanol solution to dry it, observe under the ultraviolet light, and show yellow fluorescence.
