There are many Spatholobus suberectus in Xishuangbanna, China, which is a hemorrhagic plant. This description makes Spatholobus suberectus full of mystery. What are they? Let me give you a detailed introduction, and let's get to know it together!

Spatholobus suberectus:

Spatholobus suberectus is a plant of Celastrus in Leguminosae. It is distributed in Viet Nam, Laos and Hubei, Gansu, Anhui, Zhejiang, Guangdong, Yunnan, Hunan, Hainan, Shaanxi, Guizhou, Sichuan, Guangxi, Jiangxi, Fujian and other places in Chinese mainland. It grows at an altitude of 2500 meters, mostly in ravines, hillsides, shrubs, valleys and roadsides, and has not been artificially introduced and cultivated at present. It can be used for rheumatism, arthralgia, numbness of hands and feet, quadriplegia, blood deficiency and chlorosis.

What is this?

1, the influence on hematopoietic system: according to what. The decoction *** 100%*** has the effect of enriching blood and increasing blood cells and hemoglobin in experimental anemia of rabbits. It is more effective than vetiver. * * * Zhang Shufang and others reported that Spatholobus Spatholobus Decoction * * 2g/kg * * had no obvious effect on the recovery of peripheral cells, hemoglobin and reticulocytes in rabbits with hemorrhagic anemia: 7 nests were used in the experiment, including 4 in 5 nests, 2 in 2 nests and 24 in * * * nests. Female 13, male 1 1, weight 1.42-2.58kg ... Four rabbits in the same nest were randomly divided into Salvia miltiorrhiza, Angelica sinensis, Spatholobus suberectus and control group, with 5 rabbits in each group. Only the normal values were observed in the other 4 cases. Every morning at 8:30 * * * after the first feeding * *, blood was taken from the ear vein to determine hemoglobin, red blood cell count and reticulocyte count. Once the three indexes are constant, continuous measurement for 3 days is regarded as the normal value of the rabbit. From the fourth day, blood was bled from the V-shaped mouth cut at the tip of the rabbit's ear at 8: 30 every morning. Every day 1 time for 3 consecutive days, each bleeding is equivalent to 1% of the body weight of the day, and the total amount released is equivalent to 50% of the total blood volume. After bloodletting, the stomach was perfused with 5% glucose solution to replenish the lost body fluids, and the dose was 65438+ 0% of body weight. From 1 day after bleeding, each group was given 20% Danshen Danggui Caulis Spatholobi Decoction according to 2g/lkg weight, while the other group was given normal saline according to 10ml/lkg weight as control, once a day, for 1 day, and after bleeding 1 day. The number of red blood cells and hemoglobin before bloodletting was 100%, and the average days for rabbits in each group to recover to 95% after bloodletting are shown in table 1 and table 2 respectively. The normal value of reticulocyte before bloodletting is 100%, and the peak time of reticulocyte after bloodletting and its level of 2 1 day are shown in Table 3. The above results show that Spatholobus suberectus has no obvious effect on the recovery of red blood cells, hemoglobin and reticulocytes in ear vein of rabbits with hemorrhagic anemia.

2. Effect on coagulation and fibrinolysis: Effect on coagulation and fibrinolysis of dog blood in vitro. The femoral artery was exposed after anesthesia in experimental dogs. Immediately after blood collection, * * * was put into a test tube, and anticoagulants * * * sodium oxalate and sodium citrate * * 1 were added to 9 parts of whole blood. Plasma was separated by centrifugation and divided into 3 parts, and normal saline and sodium citrate were added respectively. Recalcification time * * * reflects the intrinsic coagulation process * * *, prothrombin time, thrombin coagulation time, plasma fibrinogen quantification and gamma globulin dissolution test. It can be seen that Spatholobus suberectus * * containing 3 mg crude drug per kloc-0/ml has no obvious effect on the coagulation and fibrinolysis process of isolated dog blood.

3. Inhibiting the heart and lowering blood pressure: 50% Spatholobus suberectus decoction has a slight inhibitory effect on toad hearts in vitro and in vivo. Giving anesthetists 0.43-0.5g crude drug /kg decoction and dogs 0.3g crude drug /kg decoction can cause blood pressure drop. But it has contractive effect on isolated auricularia and toad blood vessels.

4. Anti-cancer: The in vitro test dose is 500 ng of hot water extract * * */ml, and the inhibition rate of JTC-26 is 94% and 4%; Screening anti-tumor drugs by phage method, this product has anti-phage effect.

5. Regulation of lipid metabolism: Japanese quails fed with Spatholobus suberectus decoction 6g/kg/kloc-0 for 4 days and 47 days can increase HDL2-C, decrease HDL3-C and increase HDL2-C/HDL3-C ratio, which is an important index to evaluate lipid metabolism and arteriosclerosis.

How to identify Spatholobus suberectus?

Character identification of Spatholobus suberectus

The vine is oblate and slightly curved, with a diameter of 2-7cm. The surface is grayish brown, sometimes with grayish white spots, and the cork falls off in reddish brown, with obvious longitudinal grooves and small punctate lenticels. Hard, not easy to break, the broken surface is irregular and flaky. Spatholobus suberectus slices are oval, rectangular or irregular oblique slices, with a thickness of 3-65438 00 mm. The cross-section wood is reddish brown or brown, with many duct holes and irregular arrangement, and the epidermis has resinous secretions, which are reddish brown to dark brown, and are alternately arranged with the wood into 3- 10 eccentric semicircles or rings. The pulp is small and leans to one side. Slight breathing, astringent. It is better to have more resin secretions.

Microscopic identification of Spatholobus suberectus

Cross section of stem and vine: cork cells are arranged in dozens of rows, slightly lignified to lignified, and some of them contain brown substances. The inner layer of suppository is 2-4 rows of cells, which contain brown substances. The cortex is narrow, with multiple rows of cells 10, containing yellowish brown substances; There are many stone cells scattered in groups with obvious bedding and holes. The cells are full of reddish-brown substances, and a few contain calcium oxalate crystals. The surrounding parenchyma cells contain calcium oxalate crystals, and the cell walls containing crystals are lignified and thickened. Secretory cells are few and scattered. Vascular bundle is special-shaped and consists of phloem and xylem alternately arranged into several eccentric rings. The outermost phloem of each round is a thick-walled tissue zone composed of stone cells and fibers, and the cells inside and outside the zone sometimes contain calcium oxalate crystals; The constant of phloem secretory cells is 10, which is arranged tangentially and contains yellowish brown, reddish brown or golden yellow secretions. The fiber bundles are numerous and scattered, and the surrounding cells contain calcium oxalate crystals to form crystal fibers; Stone cells are few and scattered; X-ray width is l-4 rows of cells, which are bent and often squeezed. The cambium is obvious. Many xylem vessels are scattered side by side, with a diameter of about 400μm, and some have brown blocks on their inner walls, most of which are crescent-shaped; Wood parenchyma cells mostly surround the catheter, with a slightly thicker wall and brown substance, and secretory cells are scattered in it; Wood fibers also form crystalline fibers, which are arranged in layers; The xylem ray cells have obvious pits, and some of them contain brown substances. The medulla is small and eccentric, and there are many secretory cells around it.
