In order to obtain more and detailed information, the chemical experiment methods were used to analyze the main nutritional components of mineral Ca, Mg, Fe and Vc, acid value in the nuts of 9 Fagaceae species. Some conclusions are as follows:(1) Among the 9 species, the Castanea seguinii nut has the greatest content of Ca, followed by Castanea henryi and Lithocarpus litseifolius, that in the Cyclobalanopsis gracilis nuts is the least; meanwhile, the Castanea seguinii nuts contain the most Mg, followed by Castanopsis sclerophylla and Castanopsis tibetana, but the Castanea henryi nut has the least mineral Mg. In addition, the Castanopsis sclerophylla nuts contain the greatest content of Fe, but the nuts of some species such as Castanea seguinii, Castanopsis eyrei, and Castanea henryi contain also more mineral Fe. (2) the nuts of Castanea seguinii contain rich content of Vc, followed by Castanea henryi. (3) Among these 9 species, Cyclobalanopsis gracilis nuts contain the highest acid value, followed by Cyclobalanopsis glauca, the fruits of Castanea seguinii, Castanea henryi and Castanopsis sclerophylla nuts have the moderate acidity value, which taste better and have a higher development value. In a word, the nuts of these 9 species contain rich mineral nutritional ingredients and Vc. It is considered that these species could meet the need of food industry in great scale.
