Abstract
Structure From the extracts of etiolated young asparagus (Asparagus officinalis L.), we isolated three compounds, named asparagusic acid (I), dihydroasparagusic acid (III), and S-acetyldihydroasparagusic acid (V) respectively. The structure of I, III, and V was determined by physical evidence including the use of shift reagent in NMR and was confirmed by synthesis as shown in the scheme. Physiological properties Asparagusic acids (I, III, V) inhibited the growth of the seedlings of lettuce, rice, and other plants when applied in amount of 6.67×10^<-7> M to 6.67×10^<-4> M. The extent of activity was similar to that of abscisic acid (Fig. 1 and 2). Interaction with benzyladenine, gibberellin, and indoleacetic acid In the enlargement of radish cotyledon and lettuce hypocotyl growth, the inhibitory effects of I were completely overcome by benzyladenine and GA_3 respectively (Fig 3 and 4), while I showed the inhibitory effect on the growth in the presence of IAA (Fig 5). Stimulation of Streptococcus faecalis 10 C 1 Asparagusic acid stimulated growth and respiration of Streptococcus faecalis 10 C 1. The result was shown in Table 1 and Fig. 6.
