Quantitative evaluation of phytochemical diversity in Adhatoda vasica Nees populations from five different ecogeographical regions was performed using a highly sensitive, robust and economic high performance thin layer chromatography (HPTLC) procedure. The method was validated for specificity, precision and accuracy as per the guidelines affirmed by International Conference on Harmonization of technical requirements for registration of pharmaceuticals for human use (ICH). The findings support the existence of distinct natural chemotypes within the species. Two out of the five regions had about three times higher mean vasicine content than the remaining three regions. The comparative phytochemical fingerprint profiles were quite similar except for the concentration variation seen for different alkaloids. As the quinazoline alkaloids are the biologically active compounds in A. vasica, the samples that accumulate high levels of alkaloids seem to be promising for further propagation.

Abstract  

The increase of environmental radiation dose rate during rainfall at environmental monitoring posts (MPs) was calculated by using the correlation relationship with the dose rate at the neighboring MP. The calculated dose rate agreed with the observed one within less than 20% of the maximum increase height of the observed one for each rainfall. Furthermore, when the dose rate increased due to Krypton-85 (85Kr) discharged from the Tokai Reprocessing Plant (TRP) at the environmental monitoring station (MS) downwind of the stack during rainfall, the dose rate due to the 85Kr was tried to discriminate. The discriminated dose rate agreed with that calculated by the atmospheric dispersion calculation code system, SIERRA-II, using stack monitor data and local meteorological observation data.
