Metal free protocol for the synthesis of pyrazole derivative using Dillenia indica fruit core extract

Abstract

Dillenia indica, is a medicinal plant that is grown in humid and evergreen forest of Northeastern India in particular. Its, leaves, bark and fruits are rich in various phytochemicals. In this study, we intend to extract the juice from fruit core i.e. usually a discarded waste in Indian traditional medicine and traditional cuisine. An ethanolic extract was prepared using Dillenia indica fruit core and the presence of various phytochemicals were also confirmed by performing various tests and also the pH was measured to be 4.87. Based on the acidic nature of the extract it has the potential to be used as an acid catalyst for the synthesis of Pyrazole and its derivatives under mild reaction conditions.
