AbstractIn this study, a simple and rapid liquid chromatography-mass spectrometry method was developed to simultaneously determinate five 16-deoxybarringtogenol C triterpenoid saponins with the potential of neuroprotection in rat plasma following the oral administration of the Xanthoceras sorbifolia Bunge husks extract. With digoxin as the internal standard, the plasma samples were pre-treated by ethyl acetate-isopropanol (1:1, v/v). The chromatographic separation of the five analytes was performed using a Phenomenex C18 column (250 mm × 4.6 mm, 5.0 mm) with a mobile phase of 0.05% formic acid (A)-acetonitrile (B). The mass spectrometric detection was carried out in the selected ion mode in positive ionization. The extraction recoveries of the five analytes were all over 71.28%. The established method was fully validated in line with the ICH and Food and Drug Administration (FDA) guidelines and successfully applied to the pharmacokinetic study on the five analytes in rat plasma. The terminal half-life (t1/2) of the five analytes was 2.92 ± 0.57, 5.52 ± 1.75, 2.48 ± 0.62, 2.95 ± 0.94, and 2.34 ± 0.81, respectively. This study was purposed to investigate the oral pharmacokinetic parameters and gain an in-depth insight into the reasonable preclinical use of the husks extract derived from X. sorbifolia Bunge.

Objective of this study was to determine the effect Kigelia africana fruit extract has on blood glucose levels ofdiabetes mice and its phytochemical profile. Mice were induced with diabetes using Alloxan monohydrate90mg/kg. Blood glucose was checked before induction and 72 hours after induction to confirm diabetes. Treatmentinvolved using oral administration of Kigelia fruit extract 1000mg/kg, Kigelia fruit extract 500mg/kg,Glibenclamide 0.25 mg/kg, Kigelia fruit extract 500mg/kg and Glibenclamide 0.25mg/kg and Normal Saline. Theresults showed a greater reduction in blood glucose of mice after treatment with Kigelia extract 1000mg/kgcompared to Kigelia 500mg/kg [(5.3 +/- 0.5mmol/l) vs (6.3+/- 0.6mmol/l), (p= 0.005)]. Further, Glibenclamide0.25mg/kg showed less reduction in blood glucose than Kigelia 1000mg/kg [(7.4+/-0.9mmol/l) vs (5.3 +/- 0.5), (p=0.00)]. The mean blood glucose levels were lower in mice that received Kigelia extract than those that receivedboth Kigelia extract and Glibenclamide [(5.3 +/- 0.5mmol/l) vs (7.8 +/- 0.6 mmol/l), (p=0.00)]. The fruit extracttested positive for Tannins, Saponins, Flavanoids, Alkaloids, Glycosides and Steroids. Findings of this studyindicate that Kigelia africana fruit extract causes reduction in blood glucose of diabetes induced mice and givesbetter results when used alone than in concomitant use with Glibenclamide. The study also indicates that the fruitextract has alkaloids, saponins, steroids, glycosides, tannins and flavonoids.
