Two kinds of new lectins, CATL-I and CATL-II, were partially purified from the intestine of Chlorostoma argyrostoma turbunatum by physical saline extraction, salt fractionation, ion exchange chromatography and gel filtration. CATL-I and CATL-II were purified 39.4 and 15.8 fold with a yield of 8.8 and 7.4%, respectively. On polyacrylamide gel electrophoresis, CATL-I demonstrated one major and one minor bands. This lectin agglutinated human and other animal erythrocytes nonspecifically and also agglutinated murine splenic lymphocytes. Carbohydrate specificity of the lectins was determined by inhibition of the agglutinability by methyl-${\alpha}-_D$-galactopyranoside and $_L-rhamnose$ at a final concentration of 6 mM. The lectins contained relatively high amounts of acidic amino acids, but the contents of sulfur containing amino acids were very low or was not estimated. Immunochemical studies were carried out to identify some properties of marine animal lectins.

Astilbes rhizoma has been used for headache, arthralgia, chronic bronchitis and stomachalgia in traditional chinese medicine. The analgesic activities and their components of Astilbe chinensis var. davidii Rhizomes were evaluated. The ether and ethylacetate fractions of 70% EtOH extract showed considerable analgesic activities by acetic acid induced writhing method. Compound 1~5 were isolated from ethylacetate fraction and identified as gallic acid, (+)-catechin, (+)-gallocatechin, bergenin and 11-O-galloylbergenin on the basis of spectroscopic methods. Among them (+)-gallocatechin showed stronger analgesic activity than that of other compounds.
