What are the chemical constituents of Tongkat Ali?
As early as 1968, scientific research was conducted on Eurycoma Longifolia (Tongkat Ali). At that time, the scientists were looking for natural chemicals and have identified the following phytochemical components extractable into the organic solvent. The organic solvent extract contains terpenoids, stigmasterol, sisterol, sterols, saponins, quassinoids, campesterol, benzoquinones, alkaloid, scopoletin, piscidinol, nilocitin, methhoxycantin-one-oxide, methoxycantine-one. The water soluble extract contains mainly phenolic components, tannins, high molecular weight polysaccharides, glycoprotein and mucopolysaccharide. It is believed that this water soluble component is biologically active in rendering some of the observed properties. Currently, these components are being characterized and intensive studies on the properties of these components.
