Pedicularis groenlandica is one of the most important medicinal plant of Deosai Plateau (Gilgit-Baltistan) Pakistan. The present study was aim to evaluate the micromorphological features, phytochemical screening and pharmacological potential of P. groenlandica by using multiple microscopic techniques. Six different solvents were used to prepare P. groenlandica extracts. Phytochemical and antioxidant activities were determined calorimetrically. To investigate antidiabetic, α-amylase inhibition assay was performed. Cytotoxicity was tested using brine shrimp assay. Anti-leishmanial via MTT assay. Disc-diffusion assay was used for protein kinase inhibitory, antibacterial and antifungal activities. Palyno-anatomical study showed significant variation for the authentication and correct identification of this highly therapeutic plant by using light and scanning electron microscopic techniques. All extracts were found rich in phytochemicals, significant amount of phenolic and flavonoid contents were found in methanol extract (PGM) 95.78 mg GAE/g and 66.90 mg QE/g. Highest DPPH scavenging potential with IC50 88.65 μg/mL, total antioxidant capacity (60.33 mg AAE/g sample) and total reducing power (83.97 mg AAE/g) were found for PGM. Disc-diffusion method showed significant antibacterial and antifungal activities. Noticeable growth inhibition in L. tropica was displayed by n-hexane extract (IC50 112 μg/mL). Brine shrimp with highest LD50 (67.65 μg/mL) in ethyl-acetate extract. Ethanol extract gives persuasive protein kinase inhibition (26 mm) against Streptomyces 85-E hyphae. Highest alpha-amylase inhibition (74.10%) was found in n-hexane extract. In conclusion, our findings scientifically support the ethno-medicinal and biological potential of P. groenlandica. In future, the plant needs to be explored for further identification and isolation of bioactive compounds to develop new drugs to treat several aliments.

高度治疗植物 Pedicularis groenlandica Retz 的化学分类学和生物学潜力。使用多种显微技术

Pedicularis groenlandica是巴基斯坦德奥赛高原(吉尔吉特-巴尔蒂斯坦)最重要的药用植物之一。本研究是旨在评估微形态特征,植物化学物质的筛选及药理潜在P. groenlandica通过使用多个显微技术。使用六种不同的溶剂制备P. groenlandica提取物。植物化学和抗氧化活性通过量热法测定。为了研究抗糖尿病药,进行了α-淀粉酶抑制试验。使用盐水虾测定法测试细胞毒性。通过 MTT 测定抗利什曼原虫。圆盘扩散试验用于蛋白激酶抑制、抗菌和抗真菌活性。孢粉解剖学研究表明,通过使用光和扫描电子显微技术,这种高度治疗性植物的鉴定和正确识别存在显着差异。发现所有提取物都富含植物化学物质,在甲醇提取物 (PGM) 95.78 mg GAE/g 和 66.90 mg QE/g 中发现了大量酚类和类黄酮含量。IC 50具有最高的 DPPH 清除潜力发现 PGM 的总抗氧化能力为 88.65 μg/mL(60.33 mg AAE/g 样品)和总还原能力(83.97 mg AAE/g)。圆盘扩散法显示出显着的抗菌和抗真菌活性。正己烷提取物 (IC 50 112 μg/mL)显示了L. tropica 的显着生长抑制。在乙酸乙酯提取物中具有最高 LD 50 (67.65 μg/mL) 的盐水虾。乙醇提取物对Streptomyces 85-E 菌丝提供有说服力的蛋白激酶抑制 (26 mm) 。在正己烷提取物中发现了最高的 α-淀粉酶抑制 (74.10%)。总之,我们的研究结果在科学上支持P. groenlandica的民族医学和生物学潜力. 未来,需要对该植物进行探索,以进一步鉴定和分离生物活性化合物,以开发治疗多种食物的新药物。
