(1) cortex moutan
The root bark is cylindric or semi cylindric, with longitudinal cracks, both sides curling inward, usually 3-8 cm long and 2 mm thick. The exterior is grayish brown or purplish brown, some corks have fallen off, showing brownish red, with fibrous root marks and protruding pores; the interior surface is light brown or grayish yellow, with longitudinal fine texture and shiny crystals.

② Shaving dandelion
Also known as: Pink cortex (Diannan materia medica), the surface is slightly rough, pink. The others are the same as the original Cortex Moutan.
For the above two kinds of medicinal materials, the best ones are thick and long strips, thick skin, full powder, strong aroma and many crystalline substances.
It is mainly produced in Anhui, Sichuan, Gansu, Shaanxi, Hubei, Hunan, Shandong, Guizhou and other places. In addition, it is also produced in Yunnan and Zhejiang. Sichuan and Anhui have the largest output. Fenghuangshan in Tongling, Anhui Province is the best, which is called Fengdan PI; Nanling in Anhui Province is called Yaodan PI; Dianjiang and Guanxian in Sichuan Province are called Chuandan PI; Kangding and Luding in Gansu, Shaanxi and Sichuan Province are called Xidan PI; Xichang in Sichuan Province is called Xichang Dan PI, which is inferior in quality.
In addition to the above genuine Cortex Moutan, the root bark of Paeonia suffruticosa and Paeonia suffruticosa is still used in Shaanxi Province. The varieties of Paeonia suffruticosa in Xichang are complex. Besides genuine Paeonia suffruticosa, root bark of Paeonia suffruticosa, Paeonia suffruticosa, Paeonia suffruticosa and Paeonia suffruticosa are also used.
In addition, a kind of Maodan bark, Maowen peony, is also produced in Sichuan. The root bark of Paeonia suffruticosa and Paeonia suffruticosa produced in Yunnan is the root bark of Paeonia suffruticosa and Paeonia suffruticosa.
[chemical constituents] the root contains paeonol, paeoniflorin, protopaeoniflorin and paeoniflorin. It also contains 0.15-0.4% volatile oil and phytosterols.
[pharmacological action] ① effect on central nervous system
The results showed that the intraperitoneal injection or oral administration of Paeonol in mice had sedative, hypnotic and analgesic effects; it could lower the body temperature of normal mice (intraperitoneal injection or intragastric administration); it also had antipyretic effect on artificially febrile mice (caused by injection of typhoid and PARATYPHOID BACILLI); it also had anti shock or drug-induced convulsion effect
② Antihypertensive effect
Intravenous injection of Cortex Moutan Decoction (equivalent to crude drug 0.75 g / kg) has antihypertensive effect on anesthetized dogs, cats and rats; paeonol and water decoction without paeonol also have antihypertensive effect in acute animal experiments; oral administration of experimental hypertension (primary type and renal type) in dogs or rats can produce a certain antihypertensive effect, but the effect is slow, which may be due to slow absorption in gastrointestinal tract .
③ Antibacterial action
In vitro, it has strong antibacterial effect on Staphylococcus albicans, Bacillus subtilis, Escherichia coli, typhoid bacillus, etc. Paeonia suffruticosa has significant effect on Shigella dysentery and typhoid bacilli (double dilution method in test tube), and its bactericidal power is the strongest at pH 7.0-7.6. Agar plate trenching method also proved to be effective against Salmonella typhi, Shigella dysentery, Salmonella paratyphi and Escherichia coli. Proteus, Pseudomonas aeruginosa, Staphylococcus, hemolytic streptococcus, pneumococcus, Vibrio cholerae and other bacteria have different degrees of inhibition. Paeonol can also inhibit Escherichia coli, Bacillus subtilis and Staphylococcus aureus in vitro. The extract of Paeonia suffruticosa also inhibited 10 kinds of skin fungi in vitro.
④ Other functions
The results showed that paeonol could inhibit the edema of hind paw and reduce the vascular permeability of hind paw in rats. The results of chicken embryo test showed that Paeonia suffruticosa has certain antiviral effect, but the results of intragastric administration and reinfection with influenza virus in mice are different, so its antiviral effect is still uncertain.
The hot extract of Himalayan tree peony can excite the uterus of all kinds of animals, but inhibit the frog heart, and relieve the spasm of the intestine of rabbits and guinea pigs. The ethanol extract of Paeonia suffruticosa has digitalis like effect on frog heart. It can excite uterus, inhibit intestines of rats and rabbits, and slightly reduce blood pressure of rats. However, it has no analgesic and anticonvulsant effects (shock caused by electric shock and PTZ).
