Isolation of Lauric Acid and Caffeine From Durio kutejensis Root Bark
Indonesia especially in Kalimantan has many herbs that are used by the people as traditional medicine such as pampaken (Durio kutejensis) and secondary metabolite in the root bark has potential to be explore. However, the study of Durio kutejensis root bark has not been reported. The objectives of this study were to isolate and identify secondary metabolite compounds of Durio kutejensis root bark. Secondary metabolite compounds of Durio kutejensis root bark were obtained with extraction, fractionation and purification process while identification with LCMS, 1D NMR, and 2D NMR analysis. The results were showed that the Durio kutejensis root bark contained lauric acid and caffeine.
