MILANES SANTANA, Rafael; ALONSO RODRIGUEZ, Dalyla y GONZALEZ AGUILAR, Gerardo. Farmacognosia de la droga "flores de majagua" (Hibiscus elatus Sw., familia Malvaceae): IV. Estandarización del extracto fluido. Rev Cubana Plant Med [online]. 1999, vol.4, n.2, pp. 82-87. ISSN 1028-4796.
Performing of pharmacognostic study of "flores de majagua " drug (Hibiscus elatus SW., Malvaceae family), is explained in relation to assesment of efficiency of extractive processes, Flavonoids percentage, menstrum quantity, required to obtain such percentage, and practical limitations of processes were taking in account. Authors propose use of fluid extract in hydroalcoholic menstrum to 50 %, obtained by percolation, and as a alternative variant to bimaceration. Maceration is discarded as technological process. Annexes and tables are presented. Which include quality parameters results, determined to dried up drug, and to furnace with air recirculation, to no more than 40 ?C in both tecnological variants (organoleptic, refraction rate (R.R.), pH relative density (R.D.), total solids (T.S.), alcoholic content (A.C.), capilar analysus, and qualitative chemical composition.
