This study isolated a bioactive compound from chloroform extract of Diospyros kaki (Japanese persimmon), which exhibited promising antioxidant, lipoxygenase inhibitory, and muscle relaxant activities. The results support the traditional usage of D. kaki in treating various diseases.
Diospyros kaki (Japanese persimmon) is cultivated specious of the Diospyros genus. D. kaki is a multi-medicinal application in the folk system for the cure of ischemic stroke, angina, athero-sclerosis, muscle relaxation, internal hemorrhage, hypertension, high cough, and infectious dis-ease. The main objective of this study was the isolated bioactive metabolites from chloroform fractions of D. kaki. The extract and fractions were then tested for various in-vitro (antioxidant and lipoxygenase) and in-vivo (muscle relaxant) activities. The repeated chromatographic separation of chloroform extract afforded compound 1. Compound 1, n-hexane, and chloroform fractions were evaluated for in vitro antioxidant, lipoxygenase inhibitory, and in vivo muscle relaxant potency. The chloroform extract has 79.54% interaction with DPPH at higher concentrations (100 mu g/ml) while the compound exhibited a maximum effect of 95.09% at 100 mu g/ml. Com-pound 1 exhibited significant lipoxygenase inhibitory activity with an IC50 value of 36.98 mu M followed by a chloroform extract of 57.09 mu M. Similarly, compound 1 and chloroform extract showed excellent muscle relaxant effects at a higher dose. From this investigation, it is concluded that extracts and pure compounds exhibited promising antioxidant, lipoxygenase inhibitory, and muscle relaxant activity. This study excellently rationalizes the traditional usage of D. kaki in curing various diseases. Furthermore, the docking results indicate, that the isolated compound fits well into the active site of the lipoxygenase, and makes strong interactions with the target protein.
