Isolation and characterization of novel protein with anti-fungal and anti-inflammatory properties from Aloe vera leaf gel

Int J Biol Macromol. 2011 Jan 1;48(1):38-43. doi: 10.1016/j.ijbiomac.2010.09.010. Epub 2010 Oct 1.

Abstract

The Aloe protein of 14 kDa from the Aloe vera leaf gel was isolated by an ion exchange chromatography using DEAE-cellulose and CM-cellulose column. The purified Aloe protein exhibited a potent anti-fungal activity against Candida paraprilosis, Candida krusei and Candida albicans. In addition, the purified Aloe protein also showed an anti-inflammatory property against pure lipoxygenase and cyclooxygenase-2 with 84% and 73% inhibition, respectively, and was verified by binding with these proteins by real time method by the phenomenon of surface plasmon resonance. This Aloe protein is a novel protein possessing antifungal and anti-inflammatory properties and thus sets a platform to be used as a medicinal plant product.
