STUDIES ON VARIATION OF LANATA C CONTENTS IN LEAVES OF DIGITALIS LANATA WITH RADIOIMMUNOASSAY / 第二军医大学学报

ABSTRACT

The contents of lanata C in leaves of biennial Digitalis lanata were determined by means of radioimmunoassay.The results show that the contents of lanata C in leaves of Digitalis rapidly increased half a month before blossom and reached maximum between a week before and a week after blossom, and then decreased gradually. The contents of lanata C in a day reached maximum between .1 and 6 0'clock in the afternoon.This study will provide useful information for selecting an appropriate time to collect.
