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.

Consequences of Hydro-Priming Cola parchycarpa K. Schum. and Cola rostrata K. Schum. Seeds

Hydro-priming is an important seed treatment technique for rapid seed germination. Cola species exhibits long and uneven germination. Hence this study was aimed at investigating the effect of hydro-priming durations on the germination and seedling growth of Cola parchycarpa and Cola rostrata. Five treatments (hydro-priming durations of 0 hour, 24 hours, 48 hours, 72 hours and 96 hours) were used and the experiment was laid out in a completely randomized design (CRD) with 6 replicates each. In C.

Comparative Proximate, Vitamins, Minerals and Phytochemical Analysis of Cola rostrata K. Schum. and Cola parchycarpa K. Schum

Cola rostrata and Cola parchycarpa are under-utilized indigenous kola plants, known as achicha by the Igbo natives in Nigeria, whose fruit pulps are edible and tasty. The proximate, vitamins, minerals and phytochemicals constituent of the fruit epicarp, fruit pulp and seed of C. rostrata and C. parchycarpa were evaluated using standard analytical laboratory procedures. The results revealed that C. rostrata and C. parchycarpa fruit pulps contained high moisture contents (56.56 % and 58.83 %) and carbohydrates (31.30 % and 55.39 %) respectively.
