Factory wholesale Eriocalyxin B - Esculin; Aesculin; Esculoside; Bicolorin; Escosyl – Yongjian Detail:
Application Of Esculin
Bioflavonoids, antioxidant, promote the content of vitamin C.
Action Of Esculin
1. Anti inflammation and analgesia: rats were injected intraperitoneally with 10mg / kg. Carrageenan induced, dextrose induced, serotonin induced and histamine induced “arthritis” had inhibitory effects, and the inhibitory intensities were 35,28,20,8% respectively It is also reported that it has inhibitory effect on formaldehyde induced arthritis, but the effect is weaker than that of carrageenan induced arthritis; The inhibition of dextran arthritis is not obvious It can inhibit the formation of granuloma in rats (cotton ball method), erythema reaction caused by ultraviolet radiation on the back of guinea pigs, and the increase of capillary permeability caused by histamine It has weak analgesic effect.
2. Effect on urine volume and uric acid excretion: various administration routes can enhance uric acid excretion in rats and rabbits, and have no diuretic effect on normal rats, but have significant diuretic effect on mice.
3.Others: antibacterial, anticoagulant and inhibiting aldose reductase in rat lens.

Bioactivity of Esculin
Description: esculin is a fluorescent coumarin glucoside, which is an effective component of gray bark. Esculin improves cognitive impairment in experimental diabetic nephropathy (DN) through MAPK signaling pathway, and exerts antioxidant stress and anti-inflammatory effects.
