RAMIREZ, Rubén D; PAEZ, Manuel S  y  ANGULO, Alberto A. Obtainment of Isoespintanol by Hydrodistillation and Crystallization from the Bencinic Extract of Oxandra xylopioides. Inf. tecnol. [online]. 2015, vol.26, n.6, pp.13-18. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642015000600003.

This research establishes a procedure to obtain isoespintanol (IE) by means of hydrodistillation followed by crystallization of bencinic extract of Oxandra xylopiodes. In the initial setting of the optimal conditions, monitoring by thin layer chromatography was performed in the different stages of the process, detecting the presence of isoespintanol. The proportion of IE in the hydrodistilled current was estimated by means of gas chromatography-mass spectrometry. Results suggest that the optimal concentration in the process of hydrodistillation is 4.54 mg extract/mL of water. For the purposes of the extraction with solvent, two extractions of 10 mL of dichloromethane for 10 minutes are required. The concentration process was fixed at 50°C, 1010 mbar and 80 rpm and crystallization with 200 µL of hexane and one crystal of 10 mg of IE. It is concluded that isoespintanol with a purity of 73.12% can be obtained using a simple and mot-expensive method.
