Congress grass (Parthenium hysterophorus L., family Asteraceae) is found generally in agricultural and vacant lands across the globe. This study investigated the fatty acids and elemental profiles of different parts including roots, stem and leaves of P. hysterophorus in the response to seasonal variation. The elemental analysis and fatty acid were determined in both the winter and summer seasons. The root, stem, and leaves powder were subjected to extraction with acetone, water, chloroform, diethyl ether, ethanol, methanol, and n-hexane to measure the extractive values. Among all the plant parts, leaves recorded the highest extractive value of 29%, and 28% with acetone and diethyl ether, respectively, while the root recorded the lowest (10.3%) extractive value with chloroform. Higher concentrations of saturated and unsaturated fatty acids were detected in all the plant parts in the winter collection than in the summer season. Parthenium hysterophorus is multi medicinal applications such as used for rheumatic pain, urinary tract infections, inflammation, diarrhea, neuralgia, and malaria. The study highlights the importance of collection time (seasons) of different parts of P. hysterophorus for the maximum extraction of both elements and fatty acids either saturated or unsaturated from the pharmacogenetic point of view.
