The whole herb is used for herbal cure at Andaman Islands and is grown in homestead gardens, An attempt was made to study the phytochemical composition and andrographolide content of both leaves and stem extracts. Methanolic extract yielded maximum total phenols in both leaf (24.18 mg/g) and stem extract (27.35 mg/g). Flavonoid content was also maximum in methanolic extract of leaf (52.57 mg/g) and stem (71.82 mg/g) of A. paniculata. Highest DPPH activity was found in methanolic extract in both leaf (7.08 mg BHT/g) and stem samples (7.15 mg BHT/g). The NO activity was highest in ethanolic extract in both leaf (13.85 mg vit C/g) and stem (12.86 mg Vit C/g). The methanol extract of leaf (14.65 mg EDTA/g) and stem (12.85 mg EDTA/g) showed higher chelating activity. The acetone extract of stem (3.16 mg vit c/g) and leaf (2.97 mg vit c/g) of Kalmegh showed effective reduction in the activity of hydrogen peroxide. Andrographolide content was maximum in leaf (3.49%) followed by stem (1.59%).","PeriodicalId":13738,"journal":{"name":"International Journal of Chemical Studies","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73883516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During severe infections, spots coalesced and covered the large area of the leaves. Field experiments were conducted during 2015-16 and 2016-17 to evaluate the performance of promising lines/varieties of linseed against Alternaria blight disease. Microscopic examination of pathogens in diseased tissue reveled that Alternaria linicola Groves & Skolko and Alternaria lini Dey were two fungi associated with the spots on leaves and capsules. Studies of relative dominance of pathogens associated with the diseased tissue revealed the dominance of Alternaria linicola (95.86-98.63%) in comparison to Alternaria lini (1.31-4.14%) during different growth period of linseed crop. Sixty-three genotypes were evaluated against this disease under artificial epiphytotic condition to known the level of resistance and susceptibility in different genotypes under artificial inoculated conditions.
