Abstract

Yoruba formulations are now widely accepted as medicinal formulations in rural and most urban areas among the low income earners. This study was aimed to evaluate the phytochemical constituents of these formulations. Five different formulations were purchased from traditional medical dispensers in Aluu, Choba, Alakahia, Rumuosi and Rumuokoro communities in Obio/Akpor Local Government Area of Rivers state Nigeria. Phytochemical studies revealed the presence of alkaloids, flavonoids, terpenoids, saponins, phenolics and cardiac glycosides. Phylobatanins was absent in all formulations while anthraquinones was absent in the formulation purchased in Aluu community. Quantitative analysis revealed the major components in all five formulations as; Tanins (8.35±0.327 -Aluu; 12.03±0.556-Choba; 5.67±0.231- Alakahia; 7.53±0.456-Rumuosi; 5.63±0.031- Rumuokoro), Flavonoids (4.24±0.21-Aluu; 9.06±0.055- Choba; 5.54±0.051- Alakahia; 7.35±0.021- Rumuosi; 8.13±0.062- Rumuokoro), then alkaloids (2.75±0.07-Aluu; 0.82±0.020- Choba; 5.41±0.100- Alakahia; 3.47±0.023- Rumuosi; 4.77±0.157- Rumuokoro). These phytochemicals have been implicated in several medicinal capacities, hence, the acclaimed medicinal properties of these Yoruba medicinal formulations.

Abstract

Yoruba medicinal formulations derived from plant extracts are fast becoming one of the most widely consumed medicinal formulation in the rural areas of Nigeria. The aim of this study was to screen and evaluate the effect of these medicinal formulations on cetain haematological parameters of wistar albino rats. Sixty-four rats irrespective of sex were used in this study. They were divided into six groups (control and Groups A-E); with groups A-E split into three groups for testing at week 2, 4 and 6. Each sub group contained four rats and was administered 2.9μl/Kg B.W of each medicinal formulation. Cage side examination was done daily to observe overt signs of toxicity (salivation, lacrimation, yellowing of fur etc). The formulation resulted in a significant increase then reduction in the body weight. The haematological parameters surveyed increased significantly at p < 0.05, most especially the WBC count. The increase in WBC also affirmed the presence of toxins in this formulation. The histological findings of the liver sections indicated gross cirrhosis, degeneration, inflammation and apoptosis in the experimented groups as compared to the control group. These findings suggest that, despite the reported and acclaimed benefits of this formulation, irrespective of the source, its use as a medicinal formulation should be with extreme caution. Regulation of dose and frequency of consumption of this formulation may reduce its toxic side effects

Abstract

The Yoruba formulation called Gbogbo nise is one of the most widely consumed medicinal formulation in the rural areas of Nigeria. The aim of this study was to screen for the various phytochemicals in this medicinal formulation and the effects of these formulations on some liver enzymes of wistar albino rats. Sixty-four rats irrespective of sex were used in this study. They were divided into six groups (control and Groups A-E); with groups A-E split into three sub-groups for testing at week 2, 4 and 6. Each sub group contained four rats and was administered 2.9μl/Kg B.W of each medicinal formulation. Phytochemical screening indicated the presence of alkaloids, saponins, tannins, flavonoids and terpenoids. Biochemical examination of the serum of experimental groups after 2 weeks of administration, showed an initial reduction in activities of AST, ALT and ALP when compared with control groups. For the results at weeks 4 and 6, all five formulations resulted in significant increase in the level of these marker enzymes. Thus the prolong administration of these medicinal formulation at the dosage used in the study, results in rise in liver enzymes and may be indicative of hepatic damage.

Cage side examination was done daily to observe overt signs of toxicity (salivation, lacrimation, yellowing of fur etc). The formulation resulted in a significant increase then reduction in the body weight. Markers of hepatocyte injury; alanine transaminase and aspartate transaminase, were initially reduced but increased at week 4. Same was observed for the cholestasis marker alkaline phosphatase. The levels of serum creatinine, urea and blood urea nitrogen steadily reduced over time. The histological findings of the liver sections indicated gross cirrhosis, degeneration, inflammation and apoptosis in the experimented groups as compared to the control group.
