Abstract

Synthesis of glutamide from methyl ester of rubber seed oil (Hevea brasiliensis) with glutamic acid by amidation reaction has been performed. The synthesis process involves extracting, esterification and amidation. The results showed that rubber seed oil content was 39,75%, acid number 20,98 mg KOH / gr and FFA level was 10,472%. Rubber seed oil was previously converted to methyl esters through esterification process so as to obtain a decrease of FFA to 1.34%. The result of GC-MS analysis shows the most dominant methyl ester composition is methyl linoleate which is 43,11%. The amidation process is carried out by reacting the rubber seed oil methyl esters with glutamic acid.

Abstract

A study on the synthesis of ethyl acetate from fermented cassava peel (Manihot esculenta L) with acetic acid using acid catalyst has been done. Determination of the ratio of ethanol content with the addition of yeast bread and yeast tape, also to know the rendement of ethanol and ethyl acetate contained in cassava skin. Cassava leaf flour is hydrolyzed by using concentrated hydrochloric acid (HCl) then tested by reducing sugar content by nelson somogyi method and analyzed by using UV-Vis spectrophotometry. The hydrolysis result is divided into two parts and added yeast tape and bread yeast is also added nutrient NPK each and fermented for 5 days. The fermentation results were distilled off and analyzed using Chromatography Gas (GC). The obtained ethanol is reacted with acetic acid and sulfuric acid catalyst in the esterification reaction to obtain ethyl acetate. The esterification results were analyzed by IR spectroscopy. Ethanol obtained from Chromatography Gas (GC) analysis of 13% and esterification results from IR spectroscopic analysis showed the presence of ester (ethyl acetate) formed.

Abstract

Nipah (Nypa fruticans Wurmb) is a mangrove plant from the Palmae tribe that grows along rivers that are affected by tides. The abundance of nipa palm in mangrove forests is quite high, so it has great potential to be developed. This review aims to discuss the potential anti-inflammatory activity of nipah leaves as traditional medicine, so that they can add value to nipah leaves and can be useful in the health sector. The literature search was carried out through Google Scholar and Scholar research papers related to the ability of anti-inflammatory activity in nipah leaves and other Arecaceae families. Nipah leaf extract contains secondary metabolites, namely flavonoids, phenolics, tannins, steroid saponins and triterpenoids. Flavonoids can function as inhibitors of cyclooxygenase and lipoxygenase enzymes so that they can be used to treat anti-inflammatory. Based on the literature, it can be concluded that nipah leaves are potentially effective as traditional medicine in treating inflammation or inflammation. Keywords: Nipah (Nypa fruticans Wurmb), anti-inflammatory and flavonoids

Abstract

Antiinflammatory activity tests of extract and fractions of kenitu Leaves (Chrysopyllum cainito L) in vitro were carried out. This research aimed to determine the anti-inflammatory activity of crude extract methanol of kenitu leave with protein denaturation inhibition method by using BSA (Bovine serum albumin). Diclofenac sodium was used as positive control and the negative control used the appropriate solvent. Based on phytochemical screening test, methanol extracts are known to contain secondary metabolites including flavonoids, alkaloids and phenolics. The results of the anti-inflammatory activity test of methanol extract have moderate anti-inflammatory potential with an IC50 value of 196,29 ppm.
