Fig. 3From: Vanda roxburghii: an experimental evaluation of antinociceptive properties of a traditional epiphytic medicinal orchid in animal modelsEffect of methanol extract of the V. roxburghii root and its different fractions, DS, and morphine (10 mg/kg) on formalin test (second phase). Values are mean ± S.E.M. *p < 0.05 and **p < 0.01, significantly different from control; ANOVA followed Dunnett’s test (n = 6, per group). VRM: V. roxburghii methanol extract; VRP: V. roxburghii petroleum ether fraction; VRE: V. roxburghii ethyl acetate fraction; VRC: V. roxburghii chloroform fraction; VRA: V. roxburghii aqueous fraction; DS: diclofenac sodiumBack to article page
