Comparative Gas Chromatography-Mass Spectrometry Analysis of the Leaves of Four Cola Species
This study aimed to identify, quantify and compare the phytochemical constituents present in the ethanolic leaf extracts of four Cola species - Cola acuminata, Cola rostrata, Cola parchycarpa, and Cola nitida, using Gas Chromatography-Mass Spectrometry (GC-MS). The analysis revealed varying numbers of distinct peaks: 77 for C. acuminata, 47 for C. rostrata, 43 for C. parchycarpa, and 45 for C. nitida, indicating diverse phytochemical profiles among the species. In C. acuminata, 14-Pentadecenoic acid (5.93%) was the dominant compound, with a retention time of 33.746 minutes.
