Kunth (Malva bruja o Malvaceae) JF - Revista Cubana de Química JA - Rev Cub Quim VL - 34 IS - 2 SE - DO - UR - https://cubanaquimica.uo.edu.cu/index.php/cq/article/view/5243 SP - 263-284 AB - <p>Bastardia viscosa (L.) Kunth leaf is traditionally used for digestive disorders, but there is no<br>scientific evidence on its physical-chemical quality, so its pharmacognostic characterization<br>was carried out in this work. Macromorphological and micromorphological characteristics,<br>percentages of foreign matter and blackened leaves were determined for three batches of the<br>fresh drug; a drying study was carried out and the percentage of residual moisture and ash was<br>determined for the dry drug; as well as derived extracts the percentage of total solids;<br>according to the Public Health Branch Standard 309/91. The results showed that the best<br>drying method is shade; the macromorphological characteristics coincide with the literature;<br>very low percentages of blackened leaves and foreign matter; percentages of residual moisture<br>and ashes within the permissible limits for unofficial drugs and a higher percentage of total<br>solids in 50 % ethanol.</p> ER -
