Proximate analysis of peel and seeds of Annona squamosa plant species were studied at the laboratory. The plant material of Annona squamosa was collected from wild plants found in Thane Mumbai and the herbarium specimen was prepared and authenticated from Botanical Survey of India (BSI), Government of India, Ministry of Environment and forests, Pune, India.The proximate analysis sample was analyzed.The fruits contained between 3.73 and 3.96 percent moisture in peel and 1.22 and 1.46 in seeds by Karl-Fischer method and loss on drying method respectively. 4.08%in peel and 1.12% in seeds foreign organic matters are present. 3.94%in peel and 2.39% in seeds is total ash contain. Water soluble ash is 8.18% in peel and 3.79% in seeds.Acid insoluble ash is 1.90% in peel and 1.05% in seeds
