Collectively, these chemical constituents suggest that the plant possesses significant potential for various pharmaceutical and protective applications.
Conditions
Diospyros kaki was treated with 1% potassium metabisulfite to investigate its effects on drying kinetics and quality attributes. The fruit was also subjected to 2% citric acid solutions, which proved to be a promising technique for extending storage life. Additionally, researchers utilized 2% sodium benzoate as a preservative during the drying process. Other treatments included the application of 25% aloe vera to the persimmon fruits. Finally, the study incorporated 25% honey as one of the various preservatives used to maintain the commodity's desired properties.
Preparations
Diospyros kaki is prepared as kaki-yô, which serves as a traditional hypotensive medicine in Japan. The plant is also prepared as leaves to isolate various bioactive compounds. These leaves are specifically prepared as flavone to study its effects on protein expression and cell proliferation. Furthermore, Diospyros kaki is prepared as hexane extracts to screen for distinctive vasorelaxant activity. Finally, the plant is prepared as a methanol-soluble extract for the phytochemical study and isolation of ursane- and oleanane-type triterpenoids.
Parts used
Diospyros kaki, commonly known as the persimmon, is a versatile plant that offers significant medicinal potential through its various components.
