Open Data Unverified Data
Centella asiatica pure Dew is the main component of Centella asiatica extract, its cold, bitter taste, pungent, return to the liver, spleen, kidney, with heat and dampness, detoxification swelling, hemostasis and pain, the effect of calming the nerves. Commonly used in the treatment of summer heat, sore throat, dysentery, damp-heat jaundice, blood-heat bleeding, boils swelling, bruises and other diseases.
| plant source: | asiatica |
| LogP | 0.44 at 22℃ |
| pharmacological effects | century asiatica is the dry whole grass or root whole grass of the Umbelliferae plant (Centellaasiatica(L)Urban), also known as Lei Gonggen, horseshoe grass, which can be harvested all the year round and is rich in resources. It has grown in Southeast Asia, Australia, South Africa and tropical Central Africa and has a long history of application in the field of medicine in many countries. The asiatica is cold in nature and bitter in taste. It has the effects of clearing heat and dampness, detoxification and detumescence. It is mainly used for damp-heat jaundice, heatstroke diarrhea, carbuncle swelling poison, and bruises. asiaticoside (Asiaticoside) belongs to pentacyclic triterpenoids, which has many pharmacological effects such as anti-ulcer, promoting wound healing, anti-tumor, anti-inflammatory, immune regulation, etc. At present, it is mainly used to treat scleroderma and skin trauma and burns. |
| mechanism of action | asiaticoside can act on the nucleus of fibroblasts, reducing the mitotic phase and reducing or missing the nucleolus. With the increase of drug concentration, intracellular DNA synthesis is reduced, cell growth is in an inhibited state, and the inhibition rate can reach up to 73%, suggesting that the mechanism of asiaticoside is to block the proliferation of fibroblasts, so as to reduce the synthesis of collagen and prevent scar hyperplasia. |
| application | asiaticoside (Asiaticoside) is the main component of asiaticoside. the mixture of asiaticoside a and asiaticoside B has pharmacological effects such as promoting wound healing, anti-wrinkle, anti-inflammatory, anti-depression and promoting intelligence. Comparing the pharmacological effects of asiaticoside on promoting wound healing and treating scars, it can be found that the anti-inflammatory, anti-depressant, and intelligence-promoting pharmacological effects of asiaticoside A and asiaticoside B may play a major role. |
| preparation method | weigh 500g of crushed snow grass powder, soak it in 2500ml of 75% ethanol aqueous solution, extract it by ultrasonic wave for 4 times at 50 ℃ for 1 hour each time, and concentrate the filtrate under reduced pressure to obtain 20.5g of extract. Dissolve the extract with 200ml of water, and extract it for 3 times with petroleum ether of the equal volume of the extract aqueous solution, the lower phase aqueous solution is then extracted 4 times with equal volume of ethyl acetate, and the lower phase aqueous solution is collected. The volume ratio of n-butanol and ethyl acetate of the same volume of the pooled lower phase aqueous solution is 1: 1 mixed solvent for extraction for 3 times, the upper phase extract is combined, the activated carbon decolorized extract is used, and the decolorized extract is concentrated under reduced pressure to obtain the total glucoside of centella asiatica 7.3g; Add 10 times the amount of methanol to dissolve the total glucoside of centella asiatica, filter, concentrate the filtrate, and recrystallize with an ethanol aqueous solution with a mass concentration of 90% at room temperature, the purity is 90% and the yield is 0.66%. |
