Effects of Solvents and Extraction Methods on Naringenin, LC-MS Based Quantitative Studies and Major Metabolite of Cochlospermum gossypium

Abstract

Aim: The present study was aimed to investigate “Effects of Solvents and Extraction Methods on Naringenin, LC-MS Based Quantitative Studies and major Metabolite of Cochlospermum Gossypium”. Study Design: LC-MS based Quantification Studies. Place and Duration of Study: Department of Pharmaceutical Chemistry, GITAM Institute of Pharmacy, Visakhapatnam, Andhra Pradesh between April 2019 and July 2020. Methodology: Rapid and Quantitative efficient extraction methods were used by using soxhlet and Ultrasound mediated extraction techniques for a range of polar solvents and Isolation of Naringenin by gradient elution technique, In the present study Naringenin was isolated in abundance (1%) by repetitive chromatographic purifications of the ethyl acetate extract of the bark part of C.gossypium. In view of high therapeutic potential, detailed HPLC based quantitative studies was carried out on C. gossypium bark, which contains significant levels of Naringenin. Results: The chromatographic separation was performed on the stationary phase, based on different retention mechanisms due to hydrophilic and hydrophobic interactions between compounds and stationary phase. In total, 24 different polar extracts were generated by soxhlet and ultrasound extraction methods from the two bark samples which were collected from Jaipur town (Telangana state) and Trichur town (Kerala state). Conclusion: The highest Naringenin content (0.59%) was found in the methanol + chloroform (1:1) extract (E8) generated by direct Soxhlet extraction of C.gossypium bark collected from Jaipur (Telangana state).Naringenin was isolated from a non-citrus plant for first time from Cochlospermum gosspyium and more significantly it is isolated in large quantity. It was obtained in 99.9% purity as shown by LCMS.
