HPLC-PDA-ESI-MSn analysis of different parts such as stem bark, shoot, flower, fruit and root of Capparis spinosa (C. spinosa) and Capparis decidua (C. decidua), collected in rainy and dry seasons from the Cholistan desert of Pakistan, depicted the occurrence of a wide array of phenolics with quercetin, apigenin and kaempferol derivatives along with dicaffeoylquinic acid, caffeoylquinic acid and feruloylquinic acid as the main compounds. Kaempferol-3-glucoside (28.02-167.21 μg g-1dw) was found to be the principal component in all tested parts of both species while dicaffeoylquinic acid was detected only in the flowers and roots. The roots exhibited maximum contents of flavonoids and hydroxycinnamic acid derivatives. The harvesting period significantly (p<0.05) affected the concentration of phenolics wherein the samples collected in rainy season offered greater levels of phenolics than their counterpart. The roots and fruits of both species were found to be rich sources of phenolics. The findings of this research suggest the harvesting of the selected wild Capparis species in rainy season to maximize their antioxidant and nutraceutical benefits.
