EXTRACTION OF ALKALOIDS FROM THREE NIGERIAN PLANTS, KOLA ACCUMINATA (OJI IGBO), KOLA VERA (OJI HAUSA), AND GAXCINA KOLA (BITTER KOLA)
ABSTRACT
The extraction of alkaloid from Gaxcina kola (bitter Kola), Kola acuminated (Oji Igbo) and Kola Vera (Oji Hausa) were carried out using 10% enthanoic acid and 10% ethanol to separate the alkaloid from the residue. The alkaloid was extracted using 5% ammonium hydroxide. From the sample results obtained on alkaloid for the sample 9.16% oji Igbo, 6.20% oji Hausa and 8.20% Bitter kola. It was observed that the percentage of alkaloids was highest in Oji Igbo and the least for Oji Hausa.
CHAPTER ONE
1.1 INTRODUCTION
Alkaloids are a class of organic compounds that typically contain nitrogen and have complex ring structures. They occur naturally in seed bearing plants and are found in berries, bark, fruits, roots and leaves. That is, they are derived from plants. Often, they are bases that have some physiological effects.
Many of the earliest isolated pure compounds with biological activity. This was due to the ease of isolation. The nitrogen generally makes the compound basic and the compound…
