Aims:The foliar residues of Mangiferaindica tree are usually burned or used for soil amelioration except nominal uses as fodder.Methods:To add value to this agricultural waste, extracts of the leafy residues of M. indica were studied to analyze their potential as antioxidants and to inhibit the enzymes related to the management of diabetes, Alzheimer’s Disease (AD), hepatic disorders as well as to identify important phytochemicals present in the extracts.Results:Results depicts that the leaves have notable bioactivities. The methanol extract (ME) showed much potential than ethyl acetate fraction after hydrolysis (HME) against α-amylase and α- glucosidase. The activity against the enzyme β-glucuronidase was also higher than that of the commercial β- glucuronidase inhibitor. The extract after hydrolysis showed better antioxidant and acetylcholinesterase inhibitory activities. Detection of important phytochemicals such as chrysin and myricetn, alizarin, arbutin, hydroquinone, tyrosol, taxifolin, kaempferol, mangiferin, and the vitamin alpha tocophereol, in addition to a number of organic acids, amino acids, fatty acids, sugars and polyols by GC-MS and HPTLC based analysis of the extract of M. indica leaf, also suggest the use of the leaves as sources of these important phytochemicals.Conclusion:More concisely HME with more number of detected metabolites found better to be used against oxidative stress as well as enzymes related to neural and liver disorders than that of ME.

Increasing soil carbon storage and biomass utilization is an effective process for mitigating global warming. Coal bio-briquettes (CBB) are made using two low-ranked coals with high sulfur content, corn stalks, and calcium hydroxide, and the combustion ash can ameliorate the physicochemical properties in salt-affected soil. CBB ash contains mainly calcium compounds, such as calcium sulfate, calcium hydroxide, and calcium carbonate, and coal fly ash and biomass ash. In this paper, changes in soil carbon and nitrogen content through salt-affected soil amelioration during 5 months using two CBB ashes and pig manure were examined in Northeast China. Application rates of CBB ash were 0 tha−1 (control), 11.6 tha−1, 23.2 tha−1, 46.4 tha−1, and 69.6 tha−1. Consequently, total carbon content in topsoil (0–0.15 m) after harvest of maize in all test fields indicated a range between 27.7 tCha−1 and 50.2 tCha−1, and showed increased levels compared to untreated salt-affected soil. In a 3.0% (69.6 tha−1) application plot of only CBB ash with higher carbon and higher exchangeable Ca2+, the carbon content increased by 51.5% compared to control plot, and changes in carbon sequestration compared to untreated soil was roughly twice that of the control plot. CBB ash contributed to carbon application and pig manure supply as a form of N fertilization in the case of all test plots. Changes in carbon content due to soil amelioration have a significant relationship with changes in corn production and soil chemical properties, such as pH, Na+, Cl−, sodium adsorption ratio (SAR), and exchangeable sodium percentage (ESP). Therefore, CBB production from low-ranked coal and waste biomass, and the use of CBB ash in agriculture is advocated as an effective means for sequestering carbon.
