Introduction: Investigation on the natural radionuclides 238U, 232Th, 40K and natural fallout radionuclide 210Po in the prominent plants species of Western Ghats tropical forest near Kotagiri have been carried out as a part of baseline background radiation studies in the forest environment. Materials and Methods: The prominent plants species of the region Evodia roxburghiana and Eleaocarpus obl...

In nature, fructans are synthesized from sucrose by various microbial and plant species. Depending on the source, fructans can contain from two to more than a hundred thousand fructose units linked by β-(2→1) (inulin-type) or β(2→6) (levan-type) glycosidic bonds. Bacteria produce levan or inulin polymers via a one-enzyme process aimed to confer competitiveness in the interaction with the host p...

The investigation of Thai medicinal plants for the potential therapeutic agents is surveyed with a particular emphasis on the search for antimalarial agents. The study on Diospyros mollis, Croton sublyratus, and Phyllanthus amarus is described. Thailand is uniquely located to represent the fauna and flora which characterizes the biogeographic province of Indo-Burma. A number of the eastern Hima...

We explore the ultrafast photoprotective properties of a series of sinapic acid derivatives in a range of solvents, utilizing femtosecond transient electronic absorption spectroscopy. We find that a primary relaxation mechanism displayed by the plant sunscreen sinapoyl malate and other related molecular species may be understood as a multistep process involving internal conversion of the initia...
