Chemical Components of some Hydrola (Distillated Waters) from Iranian Medicinal Plants: Chemical Components of some Hydrola from Iranian Medicinal Plants

Medicinal distilled waters (hydrola) are substances prepared by distilling water in the presence of aromatic plants or plants without fragrance. In Iran, these waters are often used for medicinal properties. Their taste and smell are similar to plants and volatile substances from which aromatic water is prepared. Some of these aromatic waters have been studied previously. In this manuscript, we have analyzed some hydrolas from some medicinal herbs in Iranian Traditional Medicine. It may be used to identify and standardize such waters. The hydrolas of 13 Iranian medicinal herbs were prepared and analyzed by GC/MS. Major  components of Tripleurospermum disciforme, Citrus aurantium, Alhagi pseudoalhagi, Foeniculum vulgare, Cuminum cyminum, Bunium persicum, Cichorium intybus, Mentha spicata, Anethum graveolens, Salix aegyptica, Zataria multiflora, Rosa damascana and Fumaria parviflora were identified. It is the first report analysis of some hydrola from Iranian medicinal plants except for rose water. This analysis may be a help to the standardization of high-consumption aromatic waters

Multi-Scale Temporal Imaging: From Micro- and Meso- to Macro-scale-time Nuclear Medicine

Time provides a common frame of reference for understanding different processes of change. Within the context of medical imaging, time has three different time scales to be considered: (i) microtime, (ii) mesotime, and (iii) macrotime, respectively, which span a single imaging session, distinct imaging sessions within a short period, and scans with large time gaps spanning months of even years. There has commonly been greater emphasis on the microtime and mesotime scales in both clinical practice and research, with less focus on questions that are at the macrotime scale
