Hawthorn medicinal properties
This product is spherical and has a diameter of 17.3~23.05mm. The surface is dark red, shiny, covered with grayish white spots; the top has a persistent flower bud, and the base has a stalk residue. Hawthorn tissue identification
The cross-section of the fruit is composed of a row of yellow-brown and thick-walled, and is composed of a class of square epidermal cells. It is 25~37.5μm long and 15~42μm wide. It is not ligated and is surrounded by the stratum corneum.
The epidermis is composed of hundreds of layers of polygonal or round-like soft cells. It is 50~145μm long and 42.5~110μm wide. It contains rich starch granules with a diameter of 4~8.75μm. The umbilical point is obvious or not obvious. A few clusters, diameter 16.25 ~ 31.25μm and yellow-brown matter, occasionally round, oval or polygonal stone cells, wood to micro-wood. The vascular bundle is located inside the mesocarp, and the xylem cells and the sieve cells are arranged side by side, micro-wood; the catheter is mainly spiral and net, with a diameter of 7.5~20μm. The endocarp is extremely thin and consists of several layers of polygonal or quasi-square soft cells.

Test liquid and sample preparation method
(1) Extraction method
The mountain medicinal material was powdered into a powder by a pulverizer, and 1.0 g of powder was weighed into a 50 mL centrifuge tube. After adding 8 mL of 70% EtOH aqueous solution, the ultrasonic wave (Branson 3200) was shaken for 15 minutes, and centrifuged with Hermle Z-400. The machine was centrifuged at 2,500 rpm for 10 min, and the supernatant was taken. The residue was further shaken with 8 mL of 70% EtOH for 15 minutes and repeated three times. The three supernatants were combined, placed in a 25 mL dosing bottle, and made up to 25 mL with 70% EtOH as a test solution.
Hawthorn chemical composition
The fruit contains epicatechin, quercetin, hyperoside, chlorogenic acid, citric acid and its monomethyl ester (citric acid symmetrical monomethyl) Ester), citric acid symmetrical dimethyl ester and citric acid trimethyl ester, sucrose, flavan polymers, ursolic acid. Hawthorn plant description
