Mango tree's fruit, mango, which grows during the summer season in India, usually March-June, is a seasonal fruit - . Mango peel gets shrunk as wrinkles of human (older people) skin when overripened. There is very much similarity in look structurally between shrunken (as wrinkles) mango peel and wrinkled skin of older people. Before the appearance of mango with wrinkled peel, mango travels a journey from flower to fruit in time which includes growing and development of mango with unwrinkled peel, increasing size over time until maturation , . Like mango, a human also travels a journey in time from birth till aged human (older people) before the appearance of a human with wrinkled skin which includes birth, childhood, teen, adult, and then becomes an old person with wrinkled skin , . Further, the basic composition of mango and human also remains the same i.e., majorly made of Carbon, Nitrogen, Oxygen, Hydrogen, Calcium, Phosphorous, and Sulphur - . Moreover, the three major components of mango are very much similar to humans such as mango pit (endocarp, seed kernel) as human bones (skeletal system), the pulp (mesocarp) as human muscles, and the mango peel (epicarp) as human skin . Based on these facts, the study of shrunken (as wrinkles) mango peel (WMP) by comparing it with unwrinkled mango peel (UMP) has been designed. Chaunsa mango was used in the experimental work of our study . The study may provide the possible reasons for the cause of wrinkles in mango peels with time after overripening. We have analyzed the samples (WMP and UMP) using FTIR (Fourier-transform infrared spectroscopy) , DSC (Differential scanning calorimetry) , , and CHNS (Carbon, Hydrogen, Nitrogen, Sulphur) elemental analyzer , . In FTIR analysis, WMP showed higher absorption intensity peak bands than UMP. In the DSC experiment, WMP was found to be more endothermic in nature compared to UMP. And from the CHNS elemental analysis, a significantly high amount of Sulphur was identified in WMP than in UMP, with approximately three times higher % compared to UMP. The significance of the results might be as such: higher absorption intensity peak bands from FTIR may be due to the presence of a higher amount of compounds containing functional groups corresponding to the peaks in WMP than UMP; more endothermic nature may signify lesser metabolic activity in WMP compared to UMP; higher % of Sulphur content suggests the presence of a significantly higher amount of Methionine and Cysteine (Sulphur) containing amino acids in WMP than UMP. As performing the same experiments on a human would be very difficult and also might be unethical, so the obtained results might have significance while interpreting the cause of human wrinkled skin with time in older people. Our study may also be helpful in the research fields dealing with human ageing as well as increasing the lifespan and longevity of humans.
