E-mail: [email protected]Figure 2: (a) Stomata on M. pudica leaf. (b) Water transport system in M. pudica (800 x 800) TEM reveals that actin cables become loose after bending. On injecting phosphatase inhibitors into several pulvinus to examine the effects of such inhibitors, it is seen that changes in actin isoforms, fragmentation of actin filaments and the bending movements are all inhibited after injecting a tyrosine phosphatase inhibitor.”! Special red cells are found on the adaxial surface of Table 3: Successive solvent extraction of Mimosa pudica Linn. leaves Chloroplast lipids show some resemblance to those of algae. The cerebroside fraction of both leaves and chloroplasts contains a polyunsaturated fatty acid (20:4w3) and a long chain sphingosine base whose R, value coincides with that from ox brain cerebroside and not that of phytosphingosine from spinachl!"7 Jasmonic acid was identified from M. pudica L. plants by mass spectrometry, high performance liquid chromatography, and thin layer chromatography. Effects of authentic jasmonic acid on pulvinule movement and transpiration of the pinnae were compared with those of abscisic acid. Jasmonic acid and abscisic acid each at 10° M inhibited both auxin- and light- induced opening of the pulvinules. A closure-inducing activity of jasmonic acid at 10-* M was greater than that of abscisic acid at 10°* M. Pinnae transpiration was reduced by 10° M abscisic acid but not by 10™* M jasmonic acid.!"*) Table 2: Detection of constituents in roots of M. pudica by chromatographic scheme Table 5: Fluorescence analysis of drug powder of Mimosa pudica Linn. leaves Figure 4: Structure of chemical constituents
