Moringa Oleifera Lam

Moringa (moringa oleifera Lam) leaves contains many molecules as inhibitors for free radicals such as phenolic compounds (phenolic acids, flavonoids, quinones, coumarins, lignans, stilbenes, tannins), nitrogen compounds (alkaloids, amines, betalain), vitamins, terpenoids (including carotenoids), and several other endogenous metabolites as antioxidants. This study aimed to determine the antioxidant potency of water and ethanol extracts of moringa (moringa oleifera Lam) leave obtained by maceration and dekok. The concentration of free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH) was analyzed using UV-Vis spectrophotometer after addition of various concentrations of Moringa leaves extracts. Various concentrations of moringa leave extracts used were 20 ppm, 40 ppm, 60 ppm and 80 ppm. Vitamin C solutions as the positive control were prepared on similar various concentrations. The negative control was prepared using DPPH solutions dissolved in absolute ethanol. The results indicated that the ethanol extract of moringa leaves prepared by maceration method showed the antioxidant potency with an IC50 value of 22.1818 ppm, but the IC50 value of water extract of moringa leaves prepared by dekok was 57.5439 ppm. While, the IC50 value of Vitamin C was 8.8084 ppm. Based on the IC50 data it can be concluded that Vitamin C is a stronger antioxidant than moringa leaves extracts.

Moringa oleifera Lam. has been used as a traditional medicine for the treatment of several diseases. In this study, the antioxidant activity and simultaneous HPLC profiling of polyphenolic compounds in 80% ethanol and water extracts of M. oleifera tender and mature leaves available in Bangladesh were investigated. The 80% ethanol extract of M. oleifera tender leaves contained high concentration and more amount of 3,4- dihydroxybenzoic acid, (-) epicatechin and rosmarinic acid (201.32±1.94, 213.08±1.96 and 133.84±1.42 mg/100 g of dry extract, respectively) than that of mature leaves (82.55±1.09, 141.86±1.10 and 16.23±0.76 mg/100 g of dry extract, respectively). On the other hand, the water extract of M. oleifera tender leaves contained a high concentration of catechin hydrate, trans-ferulic acid and quercetin (530.05±1.91, 166.38±0.90 and 771.74±1.34 mg/100 g of dry extract, respectively) than that of mature leaves (207.21±0.90, 62.42±0.45 and 483.25±1.04 mg/100 g of dry extract, respectively). It was also found that 3,4-dihydroxybenzoic acid, catechol, p-coumaric acid and trans-cinnamic acid were detected only in 80% ethanol extract of M. oleifera leaves but syringic acid was identified in the water extract. In DPPH free radical scavenging activity test, IC50 values of 80% ethanol extract of tender leaves (EETL), 80% ethanol extract of mature leaves (EEML), water extract of tender leaves (WETL) and water extract of mature leaves (WEML) were found to be moderately significant (105.50±1.05, 115.00±1.14, 216.00±1.34 and 269.50±1.56 μg/mL, respectively) when compared to the IC50 value of ascorbic acid, 3.32±0.07 μg/mL. The polyphenolic compounds are responsible for antioxidant activity. On the basis of the present study, it can be suggested that the leaves show antioxidant activity and it’s contained a significant amount and different types of polyphenolic compounds. Standardized polyphenolic compounds from M. oleifera leaves could be used as a better source of natural antioxidant supplement.

Diarrhea is still one of the most important public health problems because it is the third major contributor to child morbidity and mortality in Indonesia. One of the traditional medicines that can be used to treat diarrhea is red shoots. Red shoot leaves contain secondary metabolites such as alkaloids, flavonoids, chalcones, tannins, and terpenoids which can be used as antidiarrheals. The purpose of this study was to compare the antidiare effects between extracts of maceration and socletation of red shoot leaves and determine the effective dose of both extracts as antidiarrheal in male mice using the intestinal transit method. The treatment in this study consisted of the administration of ethanol extract of shoots of red shoots by maceration at a dose of 1.58 mg / 20 g BW (dose of MI), 4.75 mg / 20g BW (dose of M.II), 6.33 mg / 20g BB (Dosage M.III) and ethanol extract of shoots of red shoots by socletation at a dose of 1.67 mg / 20 g BB (SI dose), 5.04 mg / 20 g BB (Dosage S.II), 6.72 mg / 20 g BB (Dose S.III), Loperamid HCl as positive control, and 1% CMC suspension as negative control. Observations were made by measuring the ratio of intestinal length traveled through the norit (marker) to the total gut length. The results showed that all dose treatments on maceration and socletation ethanol extracts had antidiareal activity. Different extraction methods give the same effect in giving antidiarrheal effects. Based on Duncan's advanced dose of 6.72 mg / 20 g BW of socletation results is an effective dose as antidiarrheal because it has an effect that is not significantly different than Loperamid HCl.
