Environmental interventions and ecological adaptations harbor millions of valued substances and metabolites in plants which can be employed and commercialized for human benefits. Present study encompasses the untapped potential of pine needles of Indo-Himalayan region for the production of different metabolites and their pharmacological significance in terms of antioxidant and antimicrobial activity. Total phenolic and flavonoid content from the needles of ten pine species was quantified using three different solvent systems. Results revealed that out of 10 different selected Pinus species, Pinus taeda L. showed the highest concentration of total phenolics, Soluble-F phenolics and flavonoids content (approx. 147.02 mg/g, 141.08 mg/g and 21.91 mg/g, respectively) as compared to other species. On the other hand, Pinus greggii Engelm. ex Parl. showed the highest Bound-W phenolic content (approx. 3.62 mg/g). Among all the selected plant species, the needles of Pinus echinata Mill. exhibited the highest and Pinus thunbergii Parl. had the lowest ratio of total flavonoids to total phenolics. Most of these compounds were found to have effective antioxidant activities as well as antimicrobial activity, as estimated by oxygen radical absorbance capacity (ORAC) and disk diffusion test, respectively.
