CARVALHO, João Luiz de Souza et al. Term-stability of extractive processes from Nasturtium officinale R. Br., brassicaceae for soxhlet modified system. Quím. Nova [online]. 2009, vol.32, n.4, pp. 1031-1035. ISSN 0100-4042. http://dx.doi.org/10.1590/S0100-40422009000400034.
This work had as objective verified the term-stability of the Soxhlet modified system with analytical and pharmacothecnical application in extractive processes of Nasturtium officinale. It has proven that the process is thermo-stable. The analysis with analytical have determined 3.606 mg g-1 in chlorogenic acid and 11.813 mg g-1 in rutin (extract 1:20 w/v) and with pharmacotecnical 3.427 mg g-1 in chlorogenic acid and 11.278 mg g-1 in rutin (extract 1:6 w/v). The income of the pharmacothecnical process was inferior to the analytical, suggesting that the pharmacothecnical process would need of at least the double of time in each extraction system.
