Identification of raw herbs
Character identification
The fruit is ovoid or oblong, with an apex ripping like a fist or finger, often shrinking or curling. The outer surface is orange, yellowish green or brownish green, and the dens in the densely dented depression can sometimes be seen as fine wrinkles. The inner surface is white and scattered with yellow dots or criss-crossing vascular bundles. Hard and brittle, soft after moisture. The gas is fragrant, the outer skin is spicy and spicy, and the interior is sweet and bitter. It is better to have yellow skin and rich aroma.
1, Sichuan Buddha Tablets are small, thick and uneven. It is 4-6cm long, 3cm wide, and 3mm thick. The green side is white with a slight yellow pattern. Stronger quality, easy to break. Gas fragrance, sweet and bitter.
2, Guangfo hand piece film is thin, more wrinkle. It is 6 to 10cm long, 3 to 6cm wide, and 1 to 2mm thick. Yellow side of white scoop, pattern is obvious, softer. Smell is lighter.
Microscopic identification
Pericarp transverse section: The outer fruit pressure 1 column square forms a rectangle or round shape, the outer exocarp 2 to 3 columns of cells are smaller, the walls are slightly thick, contain calcium oxalate prisms, length 10-26μm, width 6-16μm The outer side is a large oil set 1 (~2) column, elliptical, or circular, radial 270 ~ 600μm, tangential 180 ~ 450μm: scattered inside the mesocarp there are more small vascular bundles, and orange peel crystallization. The innermost layer of the pericarp is a line of thin, fine-walled cells that are neatly organized. The cross-section of the tip of the fruit at the tip of the fruit shows that the inside of the duct or a few parenchyma cells often contain yellow cluster needles of orange peel.
Peel powder characteristics:
(1) There are more parenchyma cells and oil chamber debris.
(2) Exocarp cells are irregularly polygonal, with slightly thicker cell walls and round stomata, which can be observed.
(3) Cube crystals or prismatic crystals exist in parenchyma cells with thicker walls and thicker walls.
(4) Ladder, thread and ring catheter.
(5) Cluster needles orange peel, crystal yellow.
Physical and chemical identification
1, take this product a little trace of sublimation, you can get yellow needles or feather-like crystals. The crystals were dissolved in 95% ethanol and dropped on filter paper. Purple fluorescence was observed under the ultraviolet light (254 nm). (Check coumarin compounds)
2, take this product 0.5g, plus the amount of ethanol leaching, filtration, the filtrate plus a small amount of magnesium powder, mix, drop a few drops of concentrated hydrochloric acid, the solution was orange. (check flavonoids)
3, take this product 0.5g has been added 5% glacial acetic acid amount of leaching, filtration, the filtrate plus a few drops of bromine water, visible bromine water fading. (check lactones)

It is clinically used to prevent transient ischemic attack, myocardial infarction, artificial heart valve and venous fistula or other postoperative thrombosis.
