The Box-Behnken design was used to investigate the effect of three independent variables – time, temperature and solvent-to-solid ratio on the responses of total phenolics, total flavonoids, 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity and cupric ion reducing antioxidant capacity (CUPRAC) of date fruit methanolic extracts. Response surface analysis showed that the optimal ultrasound extraction parameters that maximized the responses were 30 min, 298 K and 74.4 ml/g. Under optimum conditions, UHPLC-DAD-MS/MS was used to tentatively characterize 11 phenolic compounds. The experimental values for the quantification of phenolic compounds and antioxidant activities are in accordance with the predicted values, indicating the suitability of the model and the success of response surface methodology in optimizing the ultrasound extraction conditions.

Boerhaavia Diffusa

The main aim of study is to evaluate the anti-arthritic effect of different extracts of Boerhaavia diffusa in arthritic rats. Different extracts were prepared by successive solvent extraction methods by using the various polar and non polar solvents and their % yields were calculated. Arthritis was induced by FCA induced arthritis model in rats and paw volume was measured on different days. Body weights of all animals were also measured simultaneously and at the end of experiment some haematological parameters were measured. On preliminary phytochemical studies extracts showed the presence of alkaloids, fatty acids, terpenoids, flavonoids and phenolic compounds. Among all extracts, methanolic extract significantly decreased the paw volume in all treated groups. Methanolic extracts also restored the body weight significantly. The results of our study revealed that all the extracts treated group’s causes significant alterations in the hematological parameters and maximal effects were observed at 400 mg/kg. Since methanolic extract showed best activity in arthritic model and its phytochemical study showed presence of flavonoids and phenolic compounds, so it may be possible that anti-arthritic activity of root extracts may be due to presence flavonoids.  Keywords: Arthritis, FCA induced arthritis, Boerhaavia diffusa, haematological parameters, and Body weight
