Black garlic possesses antioxidant effects, however, its specific antioxidant mechanism remains elusive. The present study investigates the antioxidant mechanism of black garlic using network pharmacology and molecular docking techniques. By reviewing literature and collecting the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform database, a total of 67 black garlic active ingredients and 583 potential target proteins were obtained. Taking the intersection with oxidative stress targets resulted in 357 intersection targets. After network pharmacology analysis, the core active ingredients apigenin, ferulic acid, palmitic acid, quercetin and caffeic acid were identified. The core targets are KIT, KDR and ERBB2. The core pathway is the PI3K/Akt pathway. Molecular docking results showed that KIT and ERBB2 have relatively high docking scores, and all three targets have the best binding effects with quercetin, indicating that active ingredients in black garlic such as quercetin may mainly act on targets like KIT, KDR and ERBB2 to exert antioxidant effects. Collectively, the study indicates that black garlic have good antioxidant effects at a theoretical level, providing theoretical basis for the development of functional products of black garlic.

  • The goal of the creation of a biobased economy is challenging to agriculture, forestry, academia, government and industry. The extractable resources of the Earth are finite, regardless of the quibble over when they will be depleted. The economic, political and social demands for biobased chemicals, materials and energy are expected to radically transform the materials industries, particularly the plastics industry as well as the biofuel industry. These changes will be based on the principles of sustainability, eco-efficiency, industrial ecology, and green chemistry and engineering. In keeping with the growth of knowledge in this field, there is a strong need for a forum to share original research related to biobased materials and bioenergy. The Journal of Biobased Materials and Bioenergy (JBMB) has been created as an international peer-reviewed periodical to fulfill the need for communication in these research areas. This journal will encompass related research activities in all fields of science, engineering and the life sciences.
