P. cirrhifolium, P. multiflorum and P. verticillatum are important medicinal herb of genus Polygonatum found in Himalaya and are used in many ayurvedic formulations including Chyavanprash. However, a comparative account on their biochemical attributes in Himalaya is still lacking. Therefore, the present attempt was made to explore the polyphenolics and antioxidant activity in targeted species. Result revealed a varied range of polyphenolics (i.e., phenolics 1.90–6.12; tannins 1.57–3.78; flavonols 1.30–8.59; flavonoids 1.83–7.32 mg/g dry weight, respectively) and antioxidant activity (ABTS 3.22–6.11; DPPH 0.99–1.70; FRAP 0.35–2.32 mM AAE/100 g dry weight). Results are indicative that P. verticillatum possesses higher polyphenolic activity and P. cirrhifolium is rich in DPPH and FRAP activity. However, P. verticillatum and P. cirrhifolium are threatened in wild and hence, P. multiflorum with maximum total flavonoids and total antioxidant ABTS activity can be prioritized and used as a substitute to reduce pressure on these species.

桔梗，何首乌和黄萎病菌是在喜马拉雅山发现的玉竹属的重要药用植物，并用于许多印度草药制剂中，包括Chyavanprash。但是，仍然缺乏对它们在喜马拉雅山中生化特性的比较研究。因此，本发明试图探索目标物种中的多酚和抗氧化活性。结果表明，多酚类化合物的含量范围各不相同（即，酚类化合物为1.90-6.12；单宁酸为1.57-3.78；黄酮醇为1.30-8.59；黄酮类化合物为1.83-7.32 mg / g干重）和抗氧化活性（ABTS为3.22-6.11； DPPH为0.99-1.70） ； FRAP 0.35–2.32 mA AAE / 100 g干重）。结果表明黄萎病菌具有较高的多酚活性，而青枯菌具有丰富的DPPH和FRAP活性。但是，野生的黄萎病菌和桔梗病菌受到威胁，因此可以优先考虑具有最高总黄酮含量和总抗氧化剂ABTS活性的何首乌，并以此作为替代品来减轻这些物种的压力。
