Abstract

This study sought to develop a validated reverse-phase high-performance liquid chromatography method for the quality control of the stem bark ingredients and its finished products and investigate the synergistic anti-inflammatory activity of the phytochemical constituents of C. regia stem bark. Fractionation and isolation of biomarkers were carried out by column chromatography on silica gel and monitored by thin-layer chromatography. The isolated biomarkers were characterized based on their melting points and extensive analysis of their spectroscopic data (IR, 1D and 2D NMR). The chromatographic separation was investigated and developed for the analysis of the biomarkers using µBondapakTM C18 (3.9×300 mm, 5 µm) as stationary phase. The mobile phase composition of 0.1 % trifluoroacetic acid as solvent A, and methanol as solvent B with gradient elution was finally selected. The carrageenan-induced edema in a 7-day-old chick model was used to assess the anti-inflammatory activity of the stem bark extract and compared to diclofenac sodium as a reference drug. Two compounds were successfully isolated and identified, as Regiafuran A (1) and 3,5,7,4’-Tetrahydroxy-2’-methoxyflavonol (2). The compounds were employed as biomarkers in the RP-HPLC method development. The developed method was validated and was successfully used to quantify the amount of 1 and 2 in the stem bark to be 0.224% ± 0.056%w/w and 0.354% ± 0.041%w/w respectively. The crude extract showed considerable anti-inflammatory activity compared to the reference drug, diclofenac. The method demonstrated acceptable levels of accuracy, precision, specificity, and robustness hence can be successfully adopted for routine quality control and standardization of the stem bark of C. regia. The stem bark of the plant exhibited significant anti-inflammatory activity.

Abstract

The herbs Carissa spinarum, Physalis minima and Toddalia asiatica have traditionally been used in healing diabetes, malaria and pneumonia by the communities around the Kisii region, Kenya. However in the available literature, there is scanty information on effectiveness of different plant parts of the herbs in healing the ailments. The objective of this study was to investigate the potential antimicrobial and antifungal activity of methanolic extract of whole plant Physalis minima, leaf and root of Carissa spinarum and Toddalia asiatica against gram positive bacteria Staphylococcus aureus (ATCC 25923), gram negative bacteria Escherichia coli (ATCC 25922) and fungus Candida albicans (ATCC14053). Antibiotic disc methicillin, cotrimoxazole, chloramphenicol, gentamicin, ampicillin, nalidixic and nitrofurantoin were used in the study. In each herb, plant part was extracted by soaking in methanol/dichloromethane in ratio 1:1 for a week, filtered, concentrated by rotary vapor and cooled. The same process was repeated three times for all samples. The study was conducted by agar well diffusion method. Methanolic root extract of Toddalia asiatica showed highest antibacterial activity against Staphylococcus aureus (ATCC 25923), root extract of Carissa spinarum had highest antibacterial activity against Escherichia coli (ATCC 25922) while root extract of Toddalia asiatica showed highest antifungal activity. It was concluded that root extract of Toddalia asiatica showed highest antibacterial activity 16.7mm against Staphylococcus aureus(ATCC 25923), root extract of Carissa spinarum had highest antibacterial activity 10 mm against Escherichia coli (ATCC 25922) while root extract of Toddalia asiatica had highest antifungal activity 18 mm against Candida albicans.

Abstract

Dayak onions (Eleutherine palmifolia L. Merr) is one plant that has been proven to have benefits as an antioxidant. The Dayak extract is formulated in the self nano emulsifying drug delivery system (SNEDDS) because the extract has low water solubility. The aims this study to develop the SNEDDS formulation system by testing its antioxidant activity. We determined whether there was an increase in antioxidant activity when formulated in the form of SNEDDS or not. The results were then compared with a solution of Dayak onions extract without using SNEDDS. The obtained formula was the optimal result that has been done before using the D-optimal mixture design method. The results of the components consisted of 50 mg of Dayak extract, 10 % caprylic triglyceride as oil, 1% tween 80, and 6,60 % transcutol as a combination surfactant and 12,40 % propylene glycol as co-surfactant. Antioxidant activity testing was carried out using the DPPH (1,1-Diphenyl-2-picrylhydrazyl) method. The antioxidant test using the DPPH method was done with two samples, namely the extract solution and Dayak onion extract SNEDDS. We elaborated the research by using UV-VIS spectrophotometer. Each sample was made into five concentrations, namely 30 ppm, 60 ppm, 90 ppm, 120 ppm, and 150 ppm, and carried out three times replications. The results showed that the IC50 value in the Dayak onion extract solution was 227,19 ppm (very low), while for the SNEDDS solution for the Dayak onion extract the IC50 value obtained was 38,97 ppm (very strong). The analysis was carried out next using an independent T-Test to obtain the results. There was no significant difference between the extract solution and the SNEDDS solution of Dayak onion extract.
