Piper crocatum Ruiz \& Pav is a traditional Indonesian plant that is empirically used to treat various diseases. Several studies have stated that Piper crocatum leaves extract has anti-inflammatory effects. Piper crocatum leaves contain different secondary metabolites alkaloids, flavonoids, tannin-polyphenols, steroids, terpenoids, and saponins. The purpose of this study was to determine the anti-inflammatory effect of Piper crocatum leaves extract and fraction on the production of nitric oxide in lipopolysaccharideinduced RAW 264.7 cells. Anti-inflammatory effect of methanol extract of Piper crocatum leaves (MEPC), n-hexane fraction of Piper crocatum leaves (HFPC), ethyl acetate fraction of Piper crocatum leaves (EAFPC), and n-butanol fraction of Piper crocatum leaves (BFPC) against RAW 264 cell macrophages, 7 Lipopolysaccharide-induced (LPS). Extraction of Piper crocatum leaves was the maceration method. Cell viability was determined by the MTT method in the concentration range of 12.5;25;50;100;200 ug/ mL. The anti-inflammatory effects of MEPC, HFPC, EAFPC and BFPC were tested against nitric oxide (NO) production inhibition in LPS-induced RAW 264.7 macrophage cells. NO levels were determined by the NO Colorimetric Assay Kit as measured by the ELISA plate reader. The viability test of MEPC, HFPC, EAFPC, and BFPC from Piper crocatum leaves showed the concentrations that gave the percentage of viability above 80\% were concentrations of 100, 50, and 25 g/mL. MEPC, HFPC, EAFPC, and BFPC at concentrations of 100, 50, 25 μg/mL could significantly inhibit NO production with p\<0.05 (p=0.000). The highest NO production inhibition effect was on EAFPC. MEPC, HFPC, EAFPC, and BFPC have antiinflammatory effects, with the highest effect on EAFPC.

Objective: The current study aimed to evaluate the anti-inflammatory potency of combined curcumin and capsaicin against lipopolysaccharide (LPS) induced organ damage in mice. Methods: Adult male albino mice were distributed into five experimental groups for treatment with olive oil, LPS, curcumin, capsaicin and their combination, respectively, for 7 days prior to LPS induced inflammation. At the end of the experiment, blood samples were collected and used for the analysis of serum non-specific enzymes including serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP), total bilirubin (TB), urea, creatinine and sugar, while the organ homogenates were subjected for the evaluation of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), glutothione S transferase (GST), nitric oxide (NO); lipid peroxidation (LPO) and it was further confirmed by histopathological study of different organs. Results and Conclusion: Curcumin, capsaicin and their combination had shown significant restoration of non-specific serum enzymes, antioxidant enzymes and attenuated inflammatory cells infiltration thereby preventing tissue/organ damage in LPS-challenged mice. However, the protective effect was found to be more when the two compounds were fed in combination. This beneficial potency of combined spice treatment is may be due to the contribution of diversified active moieties of curcumin and capsaicin in combination compared to individual molecules.
