Ethnobotanical Survey of Medicinal Utilization and Phytochemical Composition of Baobab Tree (Adansonia digitata L.) in Zaria Local Government Area of Kaduna State, Nigeria

Abstract

Medicinal utilization and phytochemical composition of Baobab tree (Adansonia digitata L.) in Zaria Local Government Area of Kaduna State was studied. Twenty (20) questionnaires were randomly administered in each of the six (6) districts to make a total of one hundred and twenty questionnaires (120). Ninety (90) were retrieved. The result revealed that the plant parts (leaves; stem; bark and seed) can be used in treatment and prevention of various diseases such as tuberculosis; anemia; malaria; dysentery; diarrhea; joint pains; serves as anti-diabetic; fever; urinary infection e t c. Infusion is the major (43.33%) method of herbal preparation. Parts of the plants species used in preparing the herbs include: the leaves; bark; root; seeds and fruits. Majority of the herbal are consumed in a dried form. Demographic characteristic of the respondents were also examined. The percentage of Male was (43.34%) while that of their female counter part was (56.66%). Majority (43.33%) of the respondents were between 31 – 40 years age bracket and majority (44.44%) are married with majority (37.78%) having 1-5 house hold size. 45.56% of the respondents had secondary education while 2.22% had no formal education and majority (51.11%) are traditional healers. Quantitative phytochemical analysis revealed the presence of tannins; alkaloids flavonoids; terpenoids; saponins and phenolic acid in various concentrations as there were significant differences (p < 0.05) between these phytochemicals and their plants parts. The presence of varied active ingredients in the different parts of these plants explains their diverse use in the treatment of different disease conditions. However, it is recommended that due to the increased interest in baobab products (especially on its medical utilization) and slow growth of the plant research should be directed on how to develop a new cultivar with short maturation period. Also, the local population particularly the youth should be educated and also encouraged to learn more about the tradition medicine knowledge in order to preserve it from being lost with the old genera.
