“…Antioxidant potential of the plant was studied using 2, 2′-diphenyl-1-picrylhydrazyl (DPPH˚) radical scavenging assay [22] ; β-carotene linoleate model system [23] ; reducing power assay [24] and lipid peroxidation assay [25] with some modifications using goat liver. In the modified anti-lipid peroxidation assay 2.8 ml of 10% goat liver homogenate and 0.1 ml of 50 mM, freshly prepared FeSo 4 were mixed with varying concentrations of the extract.…”

BackgroundThe quality of herbal medicine is determined by its secondary metabolites, which may vary according to growth, season and altitude etc.ObjectiveWe studied the variation in phytochemistry and biological activities of Thalictrum foliolosum (TF) roots collected from four sites at different altitudes.Material and methodsThe berberine content in different extracts of T. foliolosum roots collected from various altitudes was estimated using HPTLC. Total phenolic and flavonoid contents were determined using Folin-Ciocalteau reagent and aluminum chloride method respectively. The sensitivity of microbes for the extracts was studied using disc diffusion and the MIC was estimated using broth dilution method. Antioxidant capacity of the plant was studied using β-carotene bleaching assay, lipid peroxidation assay using goat liver, reducing power assay and DPPH free radical scavenging activity.ResultsBerberine content varied inversely with altitude; while phenol and flavonoid content of TF increased at higher altitudes. All the TF extracts showed moderate to high activity against Candida albicans, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. Extracts with high berberine content were most effective against C. albicans and S. aureus and also showed relatively significant anti-lipid peroxidation, β-carotene bleaching and reducing power. TF extracts with higher phenol and flavonoid content showed better scavenging of DPPH free radicals. Berberine was used as a standard in all the antioxidant and antimicrobial experiments performed.ConclusionThalictrum from lower elevations can be explored as an alternate source of berberine and the plant has high antioxidant and antimicrobial properties owing to its berberine content.

The mulberry leaves have been considered as a sole food source for silkworm, Bombyx mori (L.). In present work an attempt was made to investigate the role of low molecular weight peptide(s) isolated from mulberry leaves on silkworm rearing. Also we have tried to find out the role of free-radical scavenging activities of isolated peptide(s) on silkworm growth. Larval growth rate was found effective under the influence of peptide(s). Consumption rate of larvae after peptide(s) treatment on mulberry leaves was significantly enhanced over control. High antioxidant activity was found in Low molecular weight peptide(s) which have an effect on silkworm.
