Phytosterols from the seeds of petai (Parkia Speciosa)

Steroids are found in plants, animals and fungi. All steroids are made in cells either from the sterols lanosterol (animals and fungi) or from cycloartenol (plants). Both lanosterol and cycloartenol are derived from the cyclization of the triterpene squalene. Triterpenes are terpenes consisting of s...
