Physochlaina praealta samples were studied macromorphologically and cytomorphologically along with their detailed phytochemical investigation. The concentration of phytoconstituents showed a strong positive correlation with the ploidy level and altitudinal gradients. The total phenol content was detected maximum in the methanolic extract of leaves and stem of higher altitudinal plants in both cytotypes (2x, 4x). The maximum content of flavonoids was detected in the methanolic extract of root and leaves. Root organ from higher elevation possessed the highest DPPH radical scavenging activity, with the maximum percentage of inhibition being obtained in methanolic extracts. The plants of both cytotypes from higher elevations accumulate an abundant quantity of secondary metabolites. The two cytotypes differ from each other with respect to various morphometric characters thereby depicting the drastic affect of polyploidy.

宏观形态和细胞形态研究了Physochlaina praealta样品，并进行了详细的植物化学研究。植物成分的浓度与倍性水平和海拔梯度呈强正相关。在两种细胞类型中，高海拔植物叶片和茎的甲醇提取物中总酚含量最高（2x，4x）。在根和叶的甲醇提取物中检测到最大的类黄酮含量。海拔较高的根器官具有最高的DPPH自由基清除活性，在甲醇提取物中获得最大的抑制百分比。来自较高海拔的两种细胞类型的植物积累了大量的次生代谢产物。两种细胞类型在各种形态特征方面彼此不同，从而描绘了多倍体的剧烈影响。
