Banana is widely cultivated fruit around the world. The edible portion (flesh) of banana has been used for making various foods as well as eaten directly. But the outer portion (peel) is not used so much and thrown directly into the environment in most of the cases. But bioactive compounds are mostly present into the peel and in this study the comparative phytochemical, antioxidant and antibacterial property of banana peel and fleshes are evaluated. Three different varieties of unripe raw banana were selected for this study. The peel and flesh of the banana was separated, dried, crushed into coarse powder and extracted by methanol and ethyl acetate. The total phenolic and flavonoid content, total antioxidant capacity, ferrous reducing power assay and DPPH radical scavenging activity was analyzed. All the extracts have considerable amount of phenolic and flavonoid content. The extracts also exhibit very good activity in total antioxidant assay, iron reducing power activity and DPPH radical scavenging assay. The methanolic extract of Dimkumari Peel (MDP) is the most effective among all the extracts. It has phenolic content equivalent to 10.215±0.873 mg/g of GAE and flavonoid content equivalent to 9.285±0.452 mg/g of CAE. The MDP has scavenging power 69.44% at 100 μl/ml concentration which is very reasonable compared to the standard BHT 77.48%. From this study it was found that banana peel and flesh both are rich source of antioxidants.

Background: Gastrointestinal disease is a burden both for developed and developing countries. This diseases has long term complications and responsible for generation of other diseases. Aims and objectives: This work was designed to identify the age at which this disease first occurred, duration of disease, major complications like burning feelings, stool in blood, ulcer etc. Relationship between lifestyle and food habits with prevalence of disease was also assayed. Materials and methods: The data was collected from July to November 2020 by directly interviewing the patients. Results: This data was collected from 1176 patients, of them 53.74% are male and 46.25% are female. It was found that 60% of patients are taking treatments from directly supervision of physicians. This study revealed that 20.66% respondents first suffered from GI disease at 11-20 years old. Most of the patients of this study needs long time treatment and 30.27% patients are taking treatments for 1-3 years, and 25.43% for 3-6 years. Twenty nine percent of our study sample have experienced malnutrition, 83% have experienced stomach pain and 54% have experienced nausea. The food habit of patients shows that more than 70% of participants have habit of taking soft drinks, 79% have habit of street food and 43.54% participants are drinking about 2 liters of waiter daily. Conclusion:Gastrointestinal disease has a wide range of complications to the patients and disciplined lifestyle should be practiced to avoid this types of disease.
