Anti-Inflammatory Activity of Methanolic Extract of Hibiscus Plantifolius

Abstract

Objective: The objective of the present study was to carry out anti-inflammatory activity of methanolic extract of Hibiscus plantifolius (MEHP) belonging to the family Malvaceae.Methods: The shade dried stem part of H. plantifolius (1 kg) was powdered and extracted with methanol using soxhletion. The extract was concentrated using rotary evaporator under reduced pressure at 40°C, till free from the solvents and thereby providing crude methanol extract which was subsequently employed for further studies. Anti-inflammatory effect was studied by carrageenan-induced paw edema model in rats at dose level of 50, 150, and 300 mg/kg. Acute oral toxicity study was also studied.Results: The results indicate that MEHP, 300 mg/kg, exhibited significant inhibition (p<0.001) of increase in paw edema at 4th h.Conclusion: The results of the experimental study confirmed that MEHP possesses significant anti-inflammatory activity.

Biobased Silicon and Biobased Silica: Two Production Routes Whose Time has Come**

“…[39] Rice hulls are about 20 wt % of bulk grain weight, and the ash content by weight in hull is about 25 %. [40] Hence, some 39 million ton of RHA are available on a global basis, which is a far higher amount than the synthetic amorphous silica world's output of 1.03 million ton comprised of 839,000 ton "wet" silica obtained via Eq. ( 6) and "dry" silica obtained via flame pyrolytic hydrolysis of SiCl 4 at > 1000 K affording 4 mol of highly corrosive HCl per mol of silicon tetrachloride (Eq.…”
