Abstract This paper studied the synergistic effects of CaO or Al2O3 and three potassium phosphates (e.g., KH2PO4, K2HPO4·3H2O and K3PO4·3H2O) in the rice stalk pyrolysis through pyrolysis-gas chromatography-mass spectrometer (Py-GC/MS) experiments. The results show that after co-catalyzed by CaO/Al2O3 and potassium phosphates, the total contents of phenols, aldehydes, acids, LG from most samples decrease and those of ketones increase compared with those catalyzed by potassium phosphates alone. CaO/Al2O3 and potassium phosphates show synergistic effects in the regulation of the types or contents of phenols, ketones, aldehydes, etc. and are suitable for the production of ketone-rich bio-oil. Dehydration reactions, etc. are further promoted under the co-catalysis of the two catalysts, and some phenols can be converted to benzene products, etc. The contents of acetic acid can decrease to 0. For 50% K3PO4.3H2O impregnated sample, the yields of furans reduce sharply after CaO addition. For most impregnated samples except 50% K2HPO4·3H2O sample and 30%, 50% K3PO4.3H2O, the contents of total furans and furfural increase after Al2O3 addition.

Analgesic Activities

This study was to investigate the anti-inflammatory and analgesic activities of the total saponins extracted from fermented Polygala japonica Houtt (FPH) compared with that of unfermented Polygala japonica Houtt (UFPH). The total saponins extracted from FPH and UFPH were evaluated for anti-inflammatory activity in xylene-induced ear swelling and acetic acid-induced vascular permeability models in mice, analgesic activity in acetic acid-induced writhing and hot plate models in mice. The total saponins extracted from FPH had the significant anti-inflammatory (p<0.001) and analgesic (p<0.01) activities with the doses of 6 g/kg b.w. in mice. The results of this experimental study thus strongly support the potential significant use of the total saponins extracted from FPH for pain and inflammatory.

          Research has been carried out with the title "Test of the Analgetic Effect of Ethanol Extract of Jackfruit Leaves (Artocarpus heterophyllus Lam.) On Acetic Acid-induced Mice (mus musculus). Analgesics or painkillers are drugs that reduce or eliminate taste without losing consciousness. One of the traditional plants commonly used empirically is jackfruit leaves (Artocarpus heterophyllus Lam.). This study aims to determine the analgetic effect of ethanol extract of jackfruit leaves (Artocarpus heterophylus Lam.) At a dose of 100 mg / kgBB, 300 mg / kgBB and 600 mg / kgBW on acetic acid induced male mice (Mus musculus). This research is an experimental study and uses the chemical induction method. The results obtained in the form of% protection inhibition stretching ethanol extract of jackfruit leaves (Artocarpus heterophyllus Lam.) At a dose of 100mg / kgBB (28.79%); 300mg / kgBB (53.31%); 600mg / kgBB (60.70%). From the results of the research that has been done it can be concluded that the ethanol extract of jackfruit leaves (Artocarpus heterophyllus Lam.) Has the highest analgesic effect at a dose of 600mg / kgBW having a percentage of protection of 66.70%.
