Lectins, a group of highly diverse proteins of non-immune origin and are ubiquitously distributed in plants, animals and fungi, have multiple significant biological functions, such as anti-fungal, anti-viral and, most notably, anti-tumor activities. A lectin was purified from the rhizomes of
A lectin with a novel N-terminal amino acid sequence was purified from the rhizomes of Aspidistra elatior Blume by ammonium sulphate precipitation, ion exchange chromatography on diethylaminoethyl-Sepharose and carboxymethyl-Sepharose and gel filtration chromatography on Sephacryl S-100. The A.
Three new steroidal saponins, aspiletreins A-C (1-3), together with 2H-chromen-2-one (4), and α-tocopherol (5), were isolated from whole Aspidistra letreae plants collected in Vietnam. Their structures were elucidated by a combination of spectroscopic analyses, including 1D- and 2D-NMR, IR, and
