Abstract

An in-vivo anti-inflammatory study of pyrazoline compound synthesized from chalcone has been carried out using Paw Edema method.Compound (R)-3-(4-florofenil)-1-fenil-5-(tiofen-2-il)-4, 5-dihidro-1H-pyrazole was synthesized by milling method in alkaline condition,with no solvent addition and was conducted under room temperature. Characterization of the synthesized compound was determined using1H-NMR and HR-MS spectrometer. As for anti-inflammatory study, suspension of compound (R)-3-(4-florofenil)-1-fenil-5-(tiofen-2-il)-4,5-dihidro-1H-pyrazol was administrated orally to white female mice (Rattus novergicus) with doses 20, 40, 80 mg/kg bw, respectively. Theresult showed that the compound with doses 40 and 80 mg/kg bw exhibited insignificant difference compared with standard drugs Celecoxiband Piroksikam (p>0,05). Futhermore, all doses of compound did not cause any damage of stomach organ of mice, which is given the same“ulcer index” (Iu) with negative control (Iu 2,00). Meanwhile, ulcer index for Celecoxib of Iu 35,99 and Piroksikam of Iu 70,01.

Abstract

Flavanone is one of secondary metabolities included into flavonoid group that has biological activities such as anticancer, antitumor, antiproliferative, and antimicrobe. Moreover, flavanone is the biosynthesis main precursor for other types of flavonoids. In this research, 4’-methoxyflavanone has been synthesized from cyclization of 2’-hydroxychalcones derivatives by microwave irradiation using sodium acetate in ethanoland water as a catalyst. The yield obtained was 68,5 %. The purity of compound has been tested using TLC, melting point test, and HPLC. The compound was characterized by UV, IR,1 H-NMR, and MS. Toxicity activity was determined using Brine Shrimp Lethality Test (BSLT) against larvae of Arthemia salina Leach and with value LC50 = 3,29 µg/ mL. Accordings to the primary test, the flavanone compound is potentially as anticancer which was proven by LC 50 values <200 μg/mL.

Abstract

Microwave assisted hydrodistillation (MAHD) is the improvement of hydrodistillation (HD) technics which uses microwave energy as source in its refining process. The purpose of this research was to determine the best method of two extraction methods forpatchouli leaves (Pogostemon cablin Benth.). MAHD and HD methods have been compared and evaluated for its effectiveness to isolate the essential oil of fresh patchouli leaves. The results showed MAHD method offered a very important advantage exceeded HD within energy storage and isolation term. MAHD method took time for 1.5 hours whereas HD for 6 hours. The essential oil composition of extraction that determined by GC-MS. The main compounds of essential oil of  Patchouli leaves were patchouli alcohol with levels 53.00% HD and 53.10% MAHD. The density was 0.959 g/mL of HD and 0.963 g/mL of MAHD. Antimicrobial test showed te HD essential oil effectiveness was better than those of MAHD and te  effectiveness on E.coli bacteria. However, the MAHD method was to be considered enviromental friendly.
