Evodiamine- Tetradii Fructus, the fruit of the evodia plant, also known as Tetradium rutaecarpa, contains an active element that has recently been identified as evodiamine. This chemical compound is believed to be somewhat similar to capsaicin, the active compound found in the chili peppers. Some studies suggested that this vanilloid receptor agonist may interact with thermogenin, otherwise known as the uncoupling protein 1, UCP1, which is able to generate heat by a mechanism called thermogenesis. Tetradium rutaecarpa has been traditionally used in Chinese medicine for weight loss purposes and current studies seem to verify this information. Evodiamine has been embraced as a dietary supplement directed at weight loss, predominantly by the body building circles. This supplement is deemed to have energy burning and fat reducing, as well as diuretic properties.

Kaempferol is a natural flavonoid. It has been isolated from broccoli, tea, grapefruit, apples, delphinium, brussel sprouts and witch-hazel etc. Kaempferol is hardly soluble in water but highly soluble in diethyl ether and hot ethanol. It is a crystalline solid having yellow color. Many glycosides of kaempferol like astragalin and kaempferitrin, have been isolated as the ordinary products from plants. Kaempferol gives the color to the flowers Acacia decurrens and Acacia longifolia. The kaempferol has antidepressant properties. Kaempferol consumption in broccoli and tea has been related with reduced risks of heart diseases. An eight-year study established that the 3 flavonols (quercetin, kaempferol and myricetin) decreased the threat of pancreatic cancer by 23%.

Raspberry Ketones have become a chief ingredient in various food supplements these days due to their fat-burning properties. They are a chemical compound found in the fruit that give it its characteristic fruity smell and flavor. While it has most of the goodness of capsaicin that is also known to improve metabolism, it does not lead to side effects like stomach irritation. Intake of raspberry ketones leads to increase in production of a hormone called norepineprine that enhances the metabolic rate of the body by increasing its temperature. Studies reveal that raspberry ketone supplements reduce the body's ability to synthesize dietary fat. Raspberry ketone supplements not just help in reducing the fat, but also help in reducing fatty deposits in blood vessels when the norepineprine levels in the blood increase.
