Pay attention to the suitability of choosing ppe

Identification

Character identification

The fruit, together with the pods and short pedicels, is obovate-like or nearly pear-shaped, 3-5.5 mm long and 1.5-diameter.

2mm. The pupa is grayish-brown, densely brownish or gray-white fluffy, covering 2/3 or more of the entire fruit, 5 at the tip of the calyx tube, and 5-10 veins on the outer mask. The fruit is nearly spherical, slightly slightly flatter at the top, with dents in which the style falls off, and the base is slightly narrower and tan. Hard, not easily broken, yellow-brown cross-section, 4 rooms, each room has a yellow-white or yellow-brown seed 1 or infertility. Gas smell, bitter taste, astringent. It is better to use full particles.

Microscopic identification

Fruit cross-section: exocarp is a round of round cells, containing light brown particles, the outer layer of stratification; glandular hair and non-glandular hair, glandular hair head 1-2 cells, stalk single cell, non-gland Hair 1-3 cells, with axils. Underneath it is a row of parenchyma cells, round in shape, followed by 3-4 columns of tangentially elongated, parenchyma cells containing a large amount of dark brown particles. The mesocarp cells are round, radially elongated, wall-thick, and woody, with small vascular bundles on the outer ends and looping intermittently. The endocarp is 2-4 round or oval-shaped stone cells, surrounded by seeds for several extensions. There are two weeks of tough vascular bundles in the middle axis of the fruit. The outer epidermis of the seed coat is a row of flat and small parenchymal cells with 2-5 rows of reticulate cells inside.

Physical and chemical identification

(1) Take powder (40 mesh) 1g, degrease with petroleum ether, then soak in ethanol 10ml for 4-6h, filter, concentrate the filtrate to 1ml, place in 2 test tubes, add magnesium chloride powder, young acid Zinc powder reagents appear orange and cherry red in turn (check flavonoids).

(2) Thin-layer chromatography Take 1g of crude powder, add 5ml of petroleum ether, filter, and concentrate to 0.5ml for the test solution; another vitexolide plus petroleum ether is used as the reference solution. They were spotted on the same silica gel G-CMC thin-layer plate and spread with petroleum ether-ethyl acetate (3:2) with a spread of 10 cm. The color was developed with 2% vanillin sulphate solution, and the same red spot was found in the chromatogram of the test sample at the corresponding position in the chromatogram of the reference substance, and the blue color eventually became a stable light red color.
