Ferulic Acid (4-hydroxy-3-methoxycinnamic acid) is a natural UV-absorber (maximum absorbance between 300 and 320 nm) derived and extracted from rice bran. Ferulic acid is available as an odourless and pale yellow crystalline powder. It is also a powerful antioxidant. Ferulic acid, unlike p-cinnamic acid and caffeic acid, scavenges superoxide anion radicals and also inhibits lipid peroxidation induced by superoxides. In 1886 Hlasiwetz and Barth in Innsbruck, Austria isolated a dibasic acid from Ferula foetida and named this compound ferulic acid. Five years later, it was isolated again from Pinus laricio Poir by Bamberger. It is now often extracted from rice bran (Oryza sativa).
