Polyphenols and flavonoides from Momordica charantia are able to inhibite activities of enzymes catalase and peroxiadase strongly. Preparations are extracted from fruit whose are stronger and the strongest inhibition are flavonoid of fruit Momordica charantia. Polyphenols and flavonoide of Momordia charantia are different effects to peroxidase of Jour blood grounds of human serum. All most preparations are able to inhibit very strongly to peroxidase in serum of group AB from human blood, such as: Polyphenol of fruits AB > O > A >B, Polyphenol of leaves AB > A >B>O, Flavonoide of fruits AB > A >O>B, Flavonoide of leaves AB > A >O>B. Flavonoide of fruits and leaves make decrease Glucose of Cavy blood whithin six hour Cavy drank preparations. In which flavonoids of leaves decrease 15% and flavonoids from fruits do 30%. Preparation extracted from fruits and leaves of Mormordica charantia have anti bacterials. Especially flavonoids extracted from fruits have anti bacterial stronger, but they have a better fungistatic and all most have anti yeast.

Abutilon indicum contained components of the natural substances such as: amino acids, aliphatic compounds, sugars, polyphenols, flavonoids, alkaloids, glucosids. Content of polyphenols in Abutilon indicum were very high (16.92-28.62 mg/g), in which flavonoids of Abutilon indicum are various and distributed in trunk, roots and fruits, with characteristic components having absorption at 270-290 nm(flavonon).

The Lectin from Nulumbo nucifera and Telosma cordata have been extracted and purified by following process: Extraction with suitable medium precipitation with Ammoniumsunphate or Ethanol - ion exchange chromatography on CM-Cellulose of DEAE-Cellulose. Preparations having high purity showed homogeneous proteins in SDS-polyacrylamide gel-electrophoresis. pH-Optimum of the lectins from Nelumbo nucifera is pH 8.3, but form Telosma cordata is pH 5.5. The potency order of agglutination with monosaccharides was as Fructose, NAc-Glucosamine, Arabinose and NAc-acid Neuraminic for Nelumbo nucifera, but the lectin from Telosma cordata was inhibited only by Fructose, Saccharose NAc acid neuraminic. The lectins from Nelumbo nucifera and Telosma cordata were inhibited by many proteins from original Animals
