Uses
β-Amyrin acetate is a triterpenoid with potent anti-inflammatory, antifungal, anti-diabetic, anti-hyperlipidemic activities. β-Amyrin acetate can inhibit HMG-CoA reductase activity by locating in the hydrophobic binding cleft of HMG CoA reductase[1][2][3][4].
in vivo
β-Amyrin acetate (applied on the anterior surface of the right ear, 100 μg/ear, a single dose) significantly inhibits xylene-induced ear edema in mice[1].
β-Amyrin acetate (intraperitoneal injection, 4 mg/100 g, daily for 6 consecutive days) shows significant anti-inflammatory activities (43.6%) in adult albino rats[3].
β-Amyrin acetate (subcutaneous injection, 4 mg/100 g, daily for 10 days ) increases the ATP-phosphohydrolase activity in liver homogenates both in normal and arthritic rats[3].
| Animal Model: | Xylene-induced mouse ear topical edema model[1] |
| Dosage: | 50 and 100 μg/ear (5 μL) |
| Administration: | Applied on the anterior surface of the right ear |
| Result: | Inhibited Xylene-induced ear edema in mice |
| Animal Model: | Adult albino rats[3] |
| Dosage: | 4 mg/100g, daily for 6 consecutive days |
| Administration: | Intraperitoneal injection |
| Result: | Showed significant anti-inflammatory activities with mean average weight of granulation tissue of 9.2 mg after 6 days. |
