Phenolic Constituents

The antioxidant and free radical scavenging activities of Bitter Melon Momordica charantia exracts including phenolic compounds, ethanolic and aqueous were studied. Phenolic compounds were extracted, purified and identified by High Performance Liquid Chromatography (HPLC) method. The main phenolic constituents, which were present in the fruit extract of bitter melon, were gallic acid, protocatechuic acid, gentisic acid, catechin, chlorogenic acid and epicatechin. The results clearly indicated that phenolic compounds have an effective antioxidant activity by using Ferric Thiocyanate (FTC) method. Phenolic compounds caused 91.25% lipid peroxidation inhibition of linoleic acid emulsion. This activity was greater than ethanolic extract 82.5%, - tocopherol 70% and aqueous extract 49.58%. Also the phenolic compounds revealed obvious activity for H2O2 scavenging 68.8% in comparison with - tocopherol 45.3%, ethanolic extract 52.6% and aqueous extract 36.2%. These results confirmed the important role of phenolic compounds as antioxidants and the most antioxidant activity of bitter melon fruits belong to these compounds.

Herbal tea is a herbal mixture made from flowers, leaves, seeds and or roots of various plants. Some of herbal tea consumed for adds energizing, help relaxation, overcome digestive problems and also strengthen the immune system. Research on antioxidant activity and organoleptic characteristic mixflesh of bitter melon fruit (Momordica charantia L.) and red dragon fruit skin (Hylocereus lemairei (Hook.) britton & rose) herbal tea has been done. The objective of this research was to make a herbal tea formulation that has a high antioxidant activity and is preferred from a mixture of bitter melon fruitand red dragon fruit skin that has been dried at 50-60°C. The antioxidant activity were measured by free radical scavenging method with DPPH; whereas organoleptic test was measured by hedonik method. The results of 5 formulas indicate that antioxidant activity is the highest in FIII formula that has the most content of bitter melon fruit. Data were analyzed using one way ANOVA and Tukey method at 99% confidence level. The herbal tea formulation of a coarse powder mixture of 1.75 g of bitter melon fruit and a coarse powder of 0.25 g red dragon fruit showed the highest antioxidant activity with percent inhibition of 98,249% and preferably with the likes after adding 30 mL of honey.

Herbal tea is a formulation of herbal flowers, seeds, leaves, roots, and bark of various plants. It has affectiveness in energizing, healing constipation and approving immune. It has been done an experiment of antioxidant activity of herbal tea from the mixture of bitter melon (Momordica charantia L), red ginger (Zingiber officinale Roscoe) and curcuma (Curcuma xanthorrhiza Roxb). The purpose of this experiment is to make formulation of herbal tea that has strong antioxidant activity and preferably from a mixture of bitter melon (Momordica charantia L), red ginger (Zingiber officinale Roscoe) and curcuma  (Curcuma xanthorrhiza Roxb) that has been dried at a temperature of 50-60°C.The activity of antioxidant is measured by DPPH method, meanwhile organoleptic is analyzed by hedonic method. The result of the experiment from 4 formulations indicates that high antioxidant activity is FIII based on analysis one way ANOVA and Tukey test 99% true. The compositions of FIII are 1,25 g bitter melon, 0,375 g red ginger and 0,375 g curcuma has high antioxidant in 97,25%. Hedonic test indicates FIII in liking category after added 2 g palm sugar and 5mL lemon.

Wild bitter melon (Momordica charantia var. abbreviata Ser.) is a type of vine that grows wildly in the mountains and plains in Vietnam. The main use parts of the tree are fruit, stem, and leaf that can be eaten as vegetables. This study aims to (1) identify several bioactive chemical compounds in the stems and leaves of bitter melon trees in the forests in the district of Mang Yang, Gia Lai province; (2) evaluate the nutrient composition, antioxidant activity, and antimicrobial ability of fresh juice and extract with ethanol 70°. The results indicated that fresh juice and ethanol 70° extract currently inhibited the growth of experimental strains of microorganisms, in which ethanol 70o extract gives the highest antimicrobial effect. The qualitative results determined that the chemical components of wide bitter melon consist of flavonoids, saponins, tannins, free reducing sugar, organic acids, starch, and fatty acids as the basis for the standardization of exploitation of medicinal resources this material.
