      An improved method for thin-layer chromatographic analysis of saponins
      O. SHARMA*, N. KUMAR, B. SINGH, T. BHAT (*Biochemistry Laboratory, Indian Veterinary Research Institute, Regional Station, Palampur 176 061, Himachal Pradesh, India, omsharma53@yahoo.com)

      Food Chemistry 132, 671-674 (2012). TLC of saponins on silica gel with n-butanol - water - acetic acid 12:2:1. Detection by dipping into a suspension of sheep erythrocytes for 20 s, then plates were taken out and held vertically for 30 s. White spots against a pink background appeared. The plate was immersed in phosphate-buffered saline for 30 s to remove excess blood on the plate surface and again held vertically for 30 min. The method is simple, specific, convenient and time saving for analysis of saponins by TLC for purification, chemoprofiling of plants, and nutraceutical applications.
