Studies on the chemical constituents of Torreya grandis Fort. Ex Lindl

Natural products play a very important role in the medicine of the world's population. Therefore, it is important that natural product chemistry continues to explore natural resources in search of new natural products. The phytochemical analysis of Torreya grandis leaves led to the isolation of five compounds using column chromatography, Preparative High-Performance Liquid Chromatography (PHPLC) and Thin Layer Chromatography (TLC). The structures elucidation of the isolated compounds were performed by spectroscopic techniques (1H NMR, LC-MS) and identified as kaempferol (1) acacetin (2), chrysoeriol (3), wogonin (4) and dibutyl phthalate (DBP) (5). Among these, compounds 1 and 5 have not been reported from this plant.
