Ethnobotanists, microbiologists, and natural-products chemists are combing the Earth for phytochemicals and “leads” which could be a useful alternative to synthetic fungicides in the post-harvest handling of fruits and vegetables. While 25 to 50% of current medicines are derived from plants, none are used as antimicrobials. Traditional growers have long used plants to prevent or cure infectious conditions; Western medicine is trying to duplicate their successes. Plants are rich in a wide variety of secondary metabolites, such as tannins, terpenoids, alkaloids, and flavonoids, which have been found in vitro to have antimicrobial properties. The aim of this study was to access the efficacy of extracts obtained from two plants (neem and turmeric) on the extension of shelf life of mango fruits cv. Amrapalli under two storage conditions (Cool store and ambient condition). The fruits were treated with four concentrations of each plant extracts (5%, 10 %, 15% and 20 %) were placed in perforated linear low density poly ethylene bags and stored in storage conditions viz., cool storage and ambient condition, respectively. The treatment of neem leaf extract in combination with cool storage gave encouraging results. Up to the end of the storage study the treatment combination of 20 % neem leaf extract and cool store completely inhibited the pathogens, and no spoilage was observed. There was minimum physiological loss in weight (6.24 %), minimum girth reduction (0.62 %), maximum ascorbic acid content (29.96 mg/100 g of pulp), maximum acidity (0.19 %), minimum pH (5.28), maximum total soluble solids (20.96 %), maximum total sugars (12.50 %), reducing sugars (4.12 %) and non- reducing sugars (7.96 %) and best organoleptic score (7.93/10) in this interaction. The inhibitory effect of neem leaf extract was ascribed to the presence of active principle azadirachtin.
