Jute leaves (Corchorus spp.) have been used as a medicinal plant for the treatment of various diseases. The study was investigated on the antioxidant activities and HPLC profiling of polyphenolic compounds in ethanol extract of Corchorus olitorius (C. olitorius) and Corchorus capsularis (C. capsularis) leaves. The total antioxidant capacity was evaluated by phosphomolybdenum method and Identification and quantification of polyphenolic compounds were performed using HPLC-DAD system. The results indicated that eight polyphenolic compounds were found in the C. capsularis leaves but C. olitorius leaves contain six polyphenolic compounds. In fact major identified polyphenolic compounds of C. capsularis leaves were caffeic acid (CA) 55.930.13; trans-ferulic acid (FA) 58.020.18; rutin hydrate (RH) 32.160.08; ellagic acid (EA) 53.650.11 and quercetin hydrate (QU) 46.170.09 mg/100 g of dry extract respectively. Whereas in C. olitorius leaves which were rutin hydrate (RH) 152.170.51; ellagic acid (EA) 143.270.58 and quercetin hydrate (QU) 292.830.73 mg/100 g of dry extract respectively. The results showed that C. capsularis leaves contained high level of total antioxidant capacity (214.321.95 mg of ascorbic acid/g of dry extract) than that of C. olitorius (165.661.30 mg of ascorbic acid/g of dry extract) leaves. The overall data suggested that C. olitorius and C. capsularis leaves contain a significant amount of several polyphenolic compounds that could be used as a natural antioxidant for functional foods.

Abstract

Jute leaves (Corchorus spp.) have been used as a medicinal plant for the treatment of various diseases. The study was investigated on the antioxidant activities and HPLC profiling of polyphenolic compounds in ethanol extract of Corchorus olitorius (C. olitorius) and Corchorus capsularis (C. capsularis) leaves. The total antioxidant capacity was evaluated by phosphomolybdenum method and Identification and quantification of polyphenolic compounds were performed using HPLC-DAD system. The results indicated that eight polyphenolic compounds were found in the C. capsularis leaves but C. olitorius leaves contain six polyphenolic compounds. In fact major identified polyphenolic compounds of C. capsularis leaves were caffeic acid (CA) 55.930.13; trans-ferulic acid (FA) 58.020.18; rutin hydrate (RH) 32.160.08; ellagic acid (EA) 53.650.11 and quercetin hydrate (QU) 46.170.09 mg/100 g of dry extract respectively. Whereas in C. olitorius leaves which were rutin hydrate (RH) 152.170.51; ellagic acid (EA) 143.270.58 and quercetin hydrate (QU) 292.830.73 mg/100 g of dry extract respectively. The results showed that C. capsularis leaves contained high level of total antioxidant capacity (214.321.95 mg of ascorbic acid/g of dry extract) than that of C. olitorius (165.661.30 mg of ascorbic acid/g of dry extract) leaves. The overall data suggested that C. olitorius and C. capsularis leaves contain a significant amount of several polyphenolic compounds that could be used as a natural antioxidant for functional foods.
