Stanol ester Stanol ester Stanol ester is a heterogeneous group of chemical compounds known to reduce the level of low-density lipoprotein (LDL) cholesterol in blood when ingested, though to a much lesser degree than prescription drugs such as statins. The starting material is phytosterols from plants. These are first hydrogenated to give a plant stanol which is then esterified with a mixture of fatty acids also derived from plants. Plant stanol esters are found naturally occurring in small quantities in fruits, vegetables, nuts, seeds, cereals, legumes, and vegetable oils. Stanol ester is often added to rapeseed oil based margarine or other foods
Biodiversity and drugs example, caffeine, methyl salicylate and quinine. Streptomycin, neomycin, and erythromycin are derived from tropical soil fungi. A lot of plant species are used in today's studies and have been exhaustively studied for their potential value as source of drugs. It is possible that some plant species may be a source of drugs against high blood pressure, AIDS or heart troubles. In China, Japan, India and Germany, there is a great deal of interest in and support for the search for new drugs from higher plants. Each species carries unique genetic material in its DNA and in its chemical factory responding
