Polyphenols, the secondary metabolites distributed in different parts of a plant, have major role in protecting the plants from deleterious effects of ultraviolet radiations and various diseases caused by pathogens. Considering the fact that these metabolites possess tremendous medicinal properties, extensive research has been carried out during the past few decades to explore their potential health benefits. Further, polyphenols are documented to possess different activities such as antioxidant, anticarcinogenic, anti-inflammatory, antimicrobial and antiulcer. The present study pertained to analyze different polyphenolic compounds in pollen grains of 9 medicinally important plant species viz., Bauhinia variegata, B.purpurea, Cassia biflora, C. fistula, C. glauca, C. saimea and Delonix regia belonging to Fabaceae family, Hibiscus rosa-sinensis belonging to Malvaceae family and Melia azadirach belonging toMeliaceaefamily using Ultra high-performance liquid chromatography (UHPLC). Various polyphenolic compounds likecaffeic acid, catechin, chlorogenic acid, coumaric acid, ellagic acid, epicatechin, gallic acid, kaempferol, quercetin, rutin, tert-butyl hydroquinone andumbelliferonewere found to be present in the pollen grains of these plant species. The order of plant species in terms of maximum number of polyphenolic compounds was observed as Cassia saimea (10) > B. purpurea (9) = C. fistula (9) = Hibiscus rosa-sinensis (9) > Delonix regia (8) > B. variegata (6) > C. glauca (4) = Melia Azadirach (4) > C. biflora (3). The plants such as C. saimea, B. purpurea, C. fistula and H. rosa-sinensis with different polyphenolic compounds indicated their potential forthe treatment of ailments.
