Binahong Anredera cordifolia (Tenore) Steenis leaves contain chemical compounds that can be used as antioxidants. This study aims to examine the phytochemical and antioxidant activity of the ethanol extract of binahong leaves. Binahong leaves were extracted using the maceration method with an ethanol solvent. The phytochemical test showed that the ethanol extract of binahong leaves contained phenolic compounds, flavonoids, alkaloids, and tannins to have potential antioxidants. The antioxidant activity test was carried out using the DPPH method and absorbance measurement with a UV-Vis spectrophotometer at a wavelength of 517 nm. The results showed that the ethanol extract of binahong leaves had strong antioxidant activity, as evidenced by the IC50 value of 87.423 µg/mL.
One of the downstream products which can be synthesized from culilawan oil is an analog curcumin compound (AKS) with a dioxolane ring. AKS products can be synthesized using conventional and microwave methods. The method of synthesis can influence physical properties, compound geometry, and pharmacological effects. The purpose of this study was to determine the effect of the processing method on the hepatoprotective ability of AKS, and to determine a protective dose. AKS was synthesized using insulated safrole compounds from Lawang oil and involved isomerization, oxidation, and aldol condensation of curcumin analogues. At the final stage of the analog curcumin synthesis process, 2 different methods were employed: the conventional method heated the chemical in a water bath at 30 °C for 3 hours, the microwave method heated the chemical using 140 watts of power for 2 minutes. Analogs were tested in vivo in mice (Mus musculus L.) with CCl4 induced liver damage. Hepatoprotective efficacy of AKS products processed by the conventional method and the microwave method were compared using histology and liver enzyme (AST and ALT) assessment. Animals treated with conventionally produced AKS products had lower AST and lower ALT levels—and fewer histological signs of liver damage at a lower dose of AKS—than seen in either untreated animals or those treated with microwave produced AKS. Thus, products that are processed by conventional methods are more hepatoprotective.
Activity anticancer of curcumin analogous influenced by the structure, substituent and geometric isomeric. The purpose of this research was to determine the influence of curcumin analog synthesis methods against anti-cancer activity. The value of IC 50 tested in vitro against breast cancer cells T47D uses the MTT method for samples aks (1,5-bis-benzo[1.3]dioxol-5-yl-penta-1,4-dien-3-one) with a method of the process of microwave 257,798 µg/ml better than conventional method 555,276 µg/ml. The results IC 50 for samples akas (5-benzo 1.3 dioxol-5-yl-1-phenyl-penta-2,4-dien-1-one) with a method of microwave 7,247 µg/ml better than conventional method 125,300 µg/ml. Microwave method produces a product with a lower melting point and provide the results of anti-cancer activity against breast cancer cells T47D.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
