Abstract

Rosa indica symbol of godness and beauty known for various healing power, has astringent, sedative, anti-inflammatory and antidepressant qualities. Standard methods were used for qualitative detection of phyto-compounds, and quantitative detection of antioxidants was done using DPPH radical scavenging assay, total phenolics and total flavonoids content were expressed in mg GAE/g dry weight and mg QE/g dry weight. Results revealed phyto-compounds presence in all varieties under study however maximum % inhibition was observed by R. indica var pink perfume (94 ± 0.6) with IC50 value 0.3376 ± 0.01 mg/mL. Highest phenolic and flavonoid content was observed in the leaves extract of R. indica var cardinal red, i.e. 3.3553 ± 0.11 (ethanol) mg of Gallic acid equivalents (GAE)/g dry weight and 3.736 ± 0.001(ethanol) mg of quercetin equivalents (QE)/g dry weight, respectively, at conc. 0.125 mg/mL. Our finding provides evidence that all varieties of rose contain medicinally important bioactive compounds and justifies their use for treatment of different diseases.

摘要

月季是美好与美丽的象征,以多种治愈功效而闻名,具有收敛、镇静、抗炎和抗抑郁的特性。采用标准方法对植物化合物进行定性检测,使用DPPH自由基清除法对抗氧化剂进行定量检测,总酚和总黄酮含量分别以毫克没食子酸当量/克干重和毫克槲皮素当量/克干重表示。结果显示,在所研究的所有品种中均存在植物化合物,然而,粉色香水月季的抑制率最高(94 ± 0.6),IC50值为0.3376 ± 0.01毫克/毫升。在深红月季的叶片提取物中观察到最高的酚类和黄酮类含量,即在浓度为0.125毫克/毫升时,分别为3.3553 ± 0.11(乙醇)毫克没食子酸当量(GAE)/克干重和3.736 ± 0.001(乙醇)毫克槲皮素当量(QE)/克干重。我们的研究结果表明,所有品种的玫瑰都含有具有重要药用价值的生物活性化合物,证明了它们可用于治疗不同疾病。
