This article is also for Medicago sativa.
The plants of the same genus, rhinoceros indicus (also known as "snake slough grass") and rhinoceros albopictus (also known as "white flower grass" rhinoceros) are also used in Guizhou, Shaanxi and other places. The height of the plant is 10-50 cm, the leaves are finely toothed above the middle, and the flowers are 2-3 mm long. It is distributed in southwest and East China. The plant is 1-4 meters high and the Corolla is white. It is distributed in northwest, northeast and Guizhou.
[collection] the whole grass should be harvested and dried in the shade.
[chemical constituents] Melilotus officinalis contains volatile oil, coumarin, 3.5-6.3% fatty oil, 7.1% pectin and 3.16% lignin. The oil content of stem is 2-3%.
The content of protein, ether extract, crude fiber, N-free extract, carbon hydrate, calcium, phosphorus, magnesium and ash in Indian Melilotus hay was 17.70%, 2.63%, 34.14%, 35.03%, 69.17%, 0.82%, 0.29%, 0.38% and 10.50%, respectively. Coumarin, β - sitosterol and various sugars such as glucose, fructose, sorbose, raffinose and cellobiose were also isolated from fresh grass.
Luteolin contains o-hydroxycinnamic acid, namely kummaric acid, trans-o-hydroxycinnamic acid, namely o-coumaric acid, 4-hydroxycinnamic acid, namely p-coumaric acid, umbelliferide, scopoletin, luteolin, namely o-coumaric acid glucoside, kummaric acid glucoside, luteolin glucoside, namely o-hydroxyoxycinnamic acid glucoside, and glycine, serine, alanine, valine Leucine, isoleucine, proline, phenylalanine, cystine, cysteine, methionine, arginine, histidine, lysine, glutamic acid, hydroxybutyric acid, aspartic acid and tyrosine. The rotten plant contains alfalfa phenol. The root and stem contain p-coumaric acid, o-coumaric acid, chlorogenic acid and caffeic acid. The leaves and shoots contain luteolin, namely o-hydroxycinnamic acid, glucoside of luteolin, glucoside of o-coumaric acid, glucoside of luteolin and chestnut bark. Stems and leaves also contain C16 to C30 acid and C20, C24, C28 alcohol wax. Fresh Yunhua contains Robinia glycosides and other flavonoid glycosides. The seeds contain luteolin and four terpene glycosides.
[pharmacological action] Melilotus has antimalarial effect
It can reduce the number of red blood cells infected by Plasmodium in chicken malaria. With proper medication, the blood test can become negative, and it can destroy the morphology of Plasmodium, but its destruction mode is different from that of Changshan, beet, quinine, etc. A small amount of coumarin is not toxic. A large amount of coumarin can cause nausea, vomiting, vertigo, cardiac depression and cold limbs. Horses, sheep and other livestock eating too much grass can cause paralysis. It can prolong the time of hemagglutination. The extracts from leaves, stems and roots can inhibit the growth of Mycobacterium tuberculosis. The root contains saponins and has hemolytic effect (when pH is 5.6).
The plant of the same genus, rhinoceros lutea, also known as Huangling Lingxiang. It has antibacterial activity (Bacillus larva). The flavonoids contained in it have low toxicity to mice, and can prolong the coagulation time without affecting the bleeding and thrombin time. It can antagonize the vasoconstriction of pyogenin on isolated rabbit ear. Local application can inhibit the increase of capillary permeability of rabbit back skin caused by formaldehyde and propylene glycol, but the effect is not constant for histamine and egg white. These effects are similar to those of coumarin or hesperidin.
It's hard work and cool.
