To investigate the peritoneal mast cell stabilization activity of Pothos scandens extracts.
Pothos scandens L. (family- Araceae) aerial part was successively extracted with ethanol and aqueous to prepare extract of the plant. The extracts of P. scandens were evaluated for stabilization of mast cell in rat allergic models. The extract of P. scandens ethanolic, 50% aqueous ethanolic and aqueous (1, 10 and 100 μg/ml) was studied for peritoneal mast cell stabilization activity in rat mesenteric preparation induced by C 48/80.
Preliminary phytochemical analysis revealed the presence of carbohydrates, fixed oil, proteins, alkaloids, glycosides, flavonoids and phenolic compounds. The ethanolic, 50% aqueous ethanolic and aqueous extracts of P. scandens L. showed dose dependent increase in the number of intact cells when compare with C48/80 at the concentration of 10 and 100 μg/ml. It virtues further work towards the isolation of phytoconstituents from this plant.
This finding provides evidence that the P. scandens L. inhibits mast cell-derived immediate-type allergic reactions and mast cell degranulation. P. scandens has a potential as allergic anti- asthmatic agent.
研究绿萝提取物对腹腔肥大细胞稳定作用。
绿萝(天南星科)地上部分依次用乙醇和水提取,以制备植物提取物。在大鼠过敏模型中评价绿萝提取物对肥大细胞的稳定作用。研究了绿萝的乙醇提取物、50%水乙醇提取物和水提取物(1、10 和 100μg/ml)对 C48/80 诱导的大鼠肠系膜制剂中腹腔肥大细胞的稳定作用。
初步的植物化学分析表明存在碳水化合物、固定油、蛋白质、生物碱、糖苷、类黄酮和酚类化合物。与 C48/80 相比,绿萝的乙醇提取物、50%水乙醇提取物和水提取物在 10 和 100μg/ml 的浓度下,细胞完整数量呈剂量依赖性增加。这一发现进一步证明了从这种植物中分离出的植物成分具有抑制肥大细胞源性即刻型过敏反应和肥大细胞脱颗粒的作用。绿萝具有作为抗哮喘过敏剂的潜力。
