The pholyphenols in Abutilon indicum are soluble in methanol, ethanol, distilled water, and in acid medium. 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

An HPLC method was proposed to determine rapidly and simultaneously benzoic acid and salicylic acid in the benzosali ointment. The chromatographic conditions were: column lichrosorb RP 18 (25x4x10), mobile phase: methanol - 0.017 M, postassiumdihydrophosphat solution - 12.5%, tetrabutylamonium hydroxide solution (400: 800: 1.5 V/V/V) at flow rate 1-1.5ml min-1 and the detection at 230nm. Experimental results proved that the proposed HPLC method was simple, stable, accurate and precise.
