Turbinaria ornata, tropical brown algae found in the South paci c and Indian Ocean ecosystems. In accordance with recent studies, Turbinaria ornata J. has potent anti-in ammatory effects. Therefore, this study is aimed to explore the biological activities of ethanolic extract of Turbinaria ornata J by analyzing the presence of phytochemical components, antioxidant property, antimicrobial activity and the wound healing activity. From the results, phytochemical analysis of ethanolic extract of T. ornata showed the presence of alkaloids, saponins, oils, total phenolic and total avanoid content were estimated to be 0.683 Abs and 0.433 Abs respectively. Anti-oxidant activity of the ethanolic extract of T. ornata extract showed remarkable DPPH radical scavenging activity of about 58.8% at 200μg/ml and total anti-oxidant activity of 0.257 absorbance at 100μg/ml concentration, as compared to that of their respective controls. The ethanolic extract of T. ornata exhibited the maximum zone of inhibition against the clinical pathogens like Pseudomonas aeuruginosa, Escherichia coli, Staphylococcus aureus, Candida albicans and Methicillin-resistant Staphylococcus aureus with their potent anti-microbial activity. Wound healing effects of the ethanolic extract of T. ornata was analysed by using Zebra sh model. The results showed the rapidand signi cant regeneration of the wounded caudal n on day 14. Therefore, the preliminary results of this study strongly supports the ethanolic extract of T. ornata may be effective in wound healing and regeneration of the wounded tissues. HighlightsAntioxidant and Antimicrobial activities ethanolic extract of T. ornata J. supports the in vitro biological properties.The ethanolic extract of T. ornata J. reveals the promising regenerative property in zebra sh model.T. ornata J. possess strong antioxidant, antimicrobial and regenerative properties.

Millets are known as poor man crops, because they grow well in rain-fed or dry land conditions with insufficient soil fertility and water. Food shortages could become more severe in the coming years as the world population rises and arable land is depleted. As a result, various strategies are needed to ensure food security. Millets are also notable for their short growth season. They can reach maturity in as little as 85 days after being sowing. Low temperature is a major environmental factor that can limiting the plant anabolic, metabolic processes and yield globally. Temperature is an extremely important growth limiting factor because it regulates plant physiological and biochemical activity throughout the growth cycle. A field study was scheduled to estimate the low temperatures effect on plant processes such as photosynthesis, respiration, water absorption, chlorophyll stability, and yield. It was done in Rabi’ 2020 and 2021 with factorial randomized block design (FRBD) with three replications. The present study was conducted to determine the low temperature effect on growth analysis and yield of tenai genotypes screening at Agricultural College and Research Institute, Vazhavachanur. Temperature stress, particularly high or low temperatures, can disrupt plant metabolism and shorten the time of distinct plant growth phases. Plants' responses to low temperature exposure can have a significant impact on various growth parameters such as leaf area, leaf area index, crop growth rate, relative water content, photosynthetic efficiency, days to 50% flowering, number of tillers, number of grains per tiller, total dry matter production, and yield. Tenai genotypes TNSi 375 and TNSi 375 recorded higher values of specific leaf area, crop growth rate, specific leaf weight, total chlorophyll content and grain yield than other genotypes under low temperature condition, Tiruvannamali district and Jawathu hill region of Vellore district.

The antibacterial activity of the crude root extracts of the medicinal plant species, Hypochaeris radicata was studied against 15 human pathogen bacteria which includes both Gram-positive and Gramnegative strains by using agar well diffusion method. The chloroform and ethyl acetate extracts displayed broad spectrum activity against all the tested organisms but water extract showed no activity. The petroleum ether and methanol extracts showed only moderate activity. The antibacterial activity of the extracts was compared to the standard Ampicillin. The results of this present study support the plant have good antibacterial potential.

The study was aimed to explore the nutritional status of 5 indigenous edible fruits viz., Ziziphus jujuba, Limonia acidissima, Ziziphus oenoplia, Phyllanthus emblica and Ficus racemosa along with their phytochemical profile. Phosphorous content was determined using indophenol blue method; K, Ca, Mg, Fe and Zn contents were determined using atomic absorption spectrophotometer. Qualitative and quantitative estimations were carried out using standard procedures. In the present study, all the investigated samples presented substantial amount of P, Ca, Mg, Fe and Zn content. The qualitative analysis revealed the presencealkaloids, phenols and flavonoids in all the five investigated samples. However, tannins were detected only in Limonia acidissima and Ficus recemosa; whereas steroids were absent in Limonia acidissima and Phyllanthus emblica. The quantitative analysis also exhibited appreciable amount of phenolic (47 to 85 mg GAE/g sample) and flavonoid contents (12 to 61 mg RE/g sample). Thus the study confirmes that wild edible fruits investigated are a promising source of essential nutrients such as P, K, Ca, Zn, Mg and Fe. Phytochemical study also confirmed the presence of the adequate quantities of secondary metabolites of medicinal importance thus exemplifies therapeutic values.

The present study was undertaken to investigate the phytochemical profile and antioxidant activity of pomegranate fruit peels. Qualitative and quantitative phytochemical analyses were made for various solvent extracts of fruit peel of pomegranate and for antioxidant activity, ethanolic extract alone was used.The preliminary phytochemical analysis revealed that higher number of secondary metabolites was found in ethanolic extract of fruit peel than the other solvent extracts. The total phenolics and flavonoids contents of ethanolic fruit peel extract was found to be 246.5 mg GAE/100g extract and 83.95 mg QE/100g extractrespectively. The ethanolic fruit peel extracts unveiled highest scavenging ability by quenching the DPPH free radicals with the IC50 value, 142.90µg/mL. The present study showed that the tested pomegranate peels exhibited strong antioxidant activity. These results suggest that pomegranate fruit peel could be exploited as a potential source of natural antioxidant agent.
