CONVOLVULUS IS A GENUS OF ABOUT 250 SPECIES OF FLOWERING PLANTS IN THE CONVOLVULACEAE FAMILY, WIDELY DISTRIBUTED IN THE MIDDLE EAST. CONVOLVULUS PERSICUS L. IS ONE OF THE SPECIES OF THIS GENUS THAT DISTRIBUTED IN THE SOUTHERN COASTS OF CASPIAN SEA. THE AERIAL PARTS OF C. PERSICUS WERE COLLECTED FROM SARI (MAZANDARAN, IRAN) IN JUN 2011.

ANTIOXIDANTS SUCH AS PHENOLS, FLAVONOIDS AND NATURAL TANNINS ARE INCREASINGLY ATTRACTING BECAUSE THEY ARE NATURAL DISEASE PREVENTING, HEALTH PROMOTING AND ANTI-AGEING SUBSTANCES. ANTIOXIDANTS MAY SERVE THE TASK OF REDUCING OXIDATIVE DAMAGE IN HUMANS INDUCED BY FREE RADICALS AND REACTIVE OXYGEN SPECIES UNDER OXIDATIVE STRESS CONDITIONS

ANTIOXIDANTS ARE VITAL SUBSTANCES WHICH POSSESS THE ABILITY TO PROTECT THE BODY FROM DAMAGE CAUSED BY FREE RADICAL INDUCED OXIDATIVE STRESS. THERE IS AN INCREASING INTEREST IN NATURAL ANTIOXIDANTS, E.G. POLYPHENOLS, PRESENT IN MEDICINAL AND DIETARY PLANTS, WHICH MIGHT HELP PREVENT OXIDATIVE DAMAGE.

THE RELEASE OF ALLELOCHEMICALS FROM DIFFERENT WAYS HAS AN IMPORTANT ROLE IN COMPETITION OF PLANT. THE BIOASSAY METHOD WAS CONDUCTED TO SURVEY ALLELOPATHIC POTENTIAL FROM MEDICINE PLANT OF POLYGONUM CONVOLVULUS AT VARIOUS CONCENTRATIONS VIZ….

CONVOLVOLUS L. FROM CONVOLVULEA (CONVOLVOLACEAE) HAS ABOUT 250 SPECIES IN THE WORLD [1] AND 60 SPECIES IN IRAN [2]. TODAY, FLAVONOIDS ARE USED FOR MAKING ANTITUMOURE, ANTICANCER, ANTIBACTERIAL, ANTIVIRAL, ANTIFUNGAL DRUGS AND INSECTICIDES [3]. …
