COMPARISON OF SOME BIOLOGICAL ACTIVITIES AND CATECHIN TANNIN CONTENTS OF TWO JUNIPERUS AND PRUNUS SPECIES

Objective: Qualitative and quantitative determination of catechin in fruits J. communis var. saxatilis, oxycedrus subsp. oxycedrus, P. spinosa, cerasifera was analyzed by LC-MS/MS using standards. Antidiabetic, antimicrobial, antioxidant activities fruit cone extracts these plants were evaluated. analysis secondary metabolites also done. Material Method: Antimicrobial activity done with MIC. ABTS·+ DPPH• scavenging activies used activity. α-Amylase α-glucosidase inhibition assays for antidiabetic Result Discussion: JCS (IC50 = 578 ± 20 μg/ml), JOO 3706 52 PS 313 7 μg/ml) observed to show a higher than acarbose 4061 146 μg/ml). saxatilis extract MIC values between (312.5 -2500 µg/ml) against all microorganisms. has the highest phenolic composition lowest (µg GAE/ mg extract). indicated It determined that plant containing (1173.3±5.77 ng/ml) epigallocatechin (208±7.21 JCS. In this research, it can be said tannin content shows effects.
