This product is the dried and mature fruit of Schisandra sphenanthera Rehd.

[Properties] This product is spherical or oblate with a diameter of 4-6mm

[Microscopic identification] This product is powder, the skin epidermal cells have keratin lines, and the skin epidermal cells are not thickened; the oil cells are round, about 80um in diameter, and 1 row of seed coat epidermal stone cells are rectangular, about 50um in length and 20-30um in width.

【Character identification characteristics】

(1) It is spherical or oblate

(2) The surface is brownish red to dark brown, shriveled and shrunken

(3) The pulp often clings to the seeds

(4) Seeds 1-2, kidney-shaped

(5) Slightly sour taste

【Microscopic identification features】

(1) There are keratinous lines in the epidermal cells of the peel

(2) The skin epidermal cells are not thickened

(3) The oil cells are round

(4) Seed skin epidermal stone cells have a row of rectangles, and the outer wall of the cells has no protrusions

(5) The stone cells under the testa epidermis are oblong or quasi-circular, with obvious wall holes and furrows

Lilac CARYOPHYLLIFLOS

This product is the dry bud of Eugeniu caryophyllata Thunb

[Properties] This product is in the shape of a rod, 1～2cm in length, round corolla, 3～0.

【Microscopic identification】The cross section of the middle part of the calyx tube of this product: 1 row of epidermal cells with thick cuticle
.
There are 2 to 3 rows of radially elongated oval oil chambers on the outer side of the cortex, with a length of 150 to 200um; there are 20 to 50 small double-tough vascular bundles arranged intermittently in a ring, and there are a few central cylindrical sheath fibers on the periphery of the vascular bundles , Wall thickness, wood
.
The inner side is a ventilated tissue composed of several rows of parenchyma cells, with large lacunae
.
The parenchyma of the central axis is scattered with many small vascular fibers, and the parenchyma cells contain many small clusters of calcium oxalate
.
(Figure 18-24C～F)

Powder characteristics: dark reddish brown powder
.
The fiber is fusiform, with a blunt top and a thicker wall
.
There are many pollen grains, triangular in polar view, biconvex mirror-shaped in equatorial view, with 3 concentric grooves
.
There are many calcium oxalate clusters with a diameter of 4～26um, which exist in smaller parenchyma cells
.
The oil chambers are mostly broken, the secretion cells are unclear, and contain yellow oil
.

【Character identification characteristics】

(1) It is in the shape of a rod, with a brown or brownish yellow surface
.

(2) The flower buds are round, with 4 petals, arranged in a tile-like pattern
.
