Source: Bark of Cinnamomum cassia of Lauraceae.

Latin plant and animal mineral name: cinnamon. Laurel cinnamon rox ]

Harvest and storage: Generally, cinnamon can be harvested 5-6 years after planting, peeled from the stem base, dried in the sun for 1-2 days, and rolled into a tube and dried in the shade.

Primitive Ceylon Cinnamomum cassia evergreen tree, up to 10 m. The bark is dark brown, and the endothelium has a strong cinnamaldehyde aromatic gas. The branches are slightly quadrangular, gray and with white spots. Leaves opposite or almost opposite; Petiole 2 cm long, glabrous; The leaf blade is ovate or ovate-lanceolate, with a length of116cm and a width of 4.5-5.5cm The apex is tapered, the base is wedge-shaped, the upper part is green and bright, the lower part is light green and white, the two sides are hairless, and the base has three veins. The midvein and lateral vein on both sides of the leaf are raised, and the lower part of the reticular vein is honeycomb. Panicle axillary, terminal, long 10- 12 cm, silky puberulent; Bisexual flowers, about 6 mm long, yellow; Perianth tube obconical, perianth lobes 6, oblong, gray puberulent outside; 9 fertile stamens, 4-loculed anthers, hairy at the base of filament, 1 and 2 rounds of anthers with petals inward, filaments without glands, and the third round of anthers with petals outward, with 1 pair of glands at the base of filament; Ovary ovoid, glabrous, short style and discoid stigma. The fruit is oval, long 10- 15mm, black; Fruit receptacle cup-shaped, dentate, with truncated or acute tooth apex.

Habitat distribution

Ecological environment: native to Sri Lanka.

Distribution of Resources: Introduced and cultivated in Yunnan, Guangxi, Guangdong, Hainan and Taiwan Province provinces.

cultivate

1. Biological characteristics are native to tropical areas and require high temperature and high humidity habitat conditions.

2. Cultivation techniques use seeds and cuttings for propagation. Seed propagation: the storage period of germination ability of seeds under moisturizing conditions is about 1 month. 109-June, when the seeds are ripe, wash the peels after picking. 1/2d- 1/2d immediately sow in the shade. The germination rate can reach 82%- 100% when the row spacing is 20cm×5cm and the soil cover depth is1.5 m. Cutting propagation: suitable for cutting in June-August with high temperature and humidity. The cuttings should be annual branches sprouting from adult trees and annual branches of 1-3-year-old trees, and the survival rate of cuttings is high. Cuttings can be girdled or treated with high concentration naphthylacetic acid solution, which can effectively improve the rooting survival rate of cuttings. At seedling stage, we should set up a shed for shade, and pay attention to weeding, loosening soil and fertilizing. After 1 year cultivation, dig holes at the row spacing of 5m×4m for planting. Pay attention to watering and moisturizing within 1 month after planting, weed and loosen the soil according to the weed situation in late winter and early spring every year, and apply fertilizer appropriately.

Character; Role; letter

1. Trait identification branch bark is usually a slender composite roll formed by overlapping 7- 12 layers or multiple layers of thin sheets, with a length of 60cm, a tube width of about 1cm and a thickness of about 0.5 mm, and the outer surface is yellow-brown, flat, with wavy vertical stripes and occasional marks and holes (where branches extend). The inner surface is darker in color. The smell is sweet and fragrant.

2. Microscopic identification of branch bark cross section: cork layer is a series of cells.

The outer wall of the innermost cell thickens.

Wood (imported cork removed). There are scattered stone cells and secretory cells in cortex.

Stone cells usually have thin outer walls.

Stone cells are intermittently scattered in the pericycle sheath.

Not connected in a loop.

The phloem has rectangular stone cells arranged tangentially in 10-25 columns; There are fewer bast fibers outside.

There's more inside.

Single beam or 2-4 beams

The fiber diameter is mostly below 30μ m.

chemical composition

Bark contains volatile oil. The volatile oil from the original bark contains cinnamaldehyde 45%-65%, eugenol 65,438+02%-65,438+08%. The volatile oil from introduced bark (Xishuangbanna) contains 46.5% cinnamaldehyde and a small amount of eugenol.

Bark also contains octenylalanine, octenyllanolin, proanthocyanidins) I, II, III, IV and arabinoxylan. The stem bark contains D- glucan.

Leaves contain volatile oil.

The basic component of oil is eugenol.

And the content is high.

The country of origin is 82.5% ~ 83%

The introduction area (Xishuangbanna) is 79. 1% ~ 82.6%.

Cinnamaldehyde content is low.

In addition, it also contains α -pinene

α -phellandrene (α-phellandrene)

Paracymene

linalool

β -caryophyllene (β-caryophyllene)

α-terpineol (α-terpineol)

Benzyl acetate, cinnamyl acetate, benzyl benzoate, etc.

pharmacological action

1. Anti-ulcer effect The water extract of Cinnamomum cassia from Sri Lanka was taken orally at the weight of 0.5g (crude drug) /kg and 2.5g (crude drug) /kg for three consecutive days to inhibit the formation of stress ulcer in mice.

2. Effect on the model of yang deficiency induced by glucocorticoid: Oral administration of water extract of Cinnamomum cassia in Sri Lanka at the weight of 0.5g (crude drug) /kg and 2.5g (crude drug) /kg for 6 consecutive days has inhibitory effects on thymus atrophy and hypercholesterolemia induced by high dose of flumethasone.

3. The LD50 of the toxic water extract of Cinnamomum cassia in Sri Lanka is 51.8 3.0g (crude drug) /kg body weight; After administration, the mice showed fatigue, little movement, loose fur, muscle weakness, disappearance of righting reflex and weak breathing. Most of the dead mice were prone, and no obvious abnormalities were found in various organs at autopsy.
