GUASPE-ANGLADA, Yaribey; HECHAVARRIA-GUILLEN, Leydis  e  OCHOA-PACHECO, Ania. Pharmacognostic caracterization of the leaf from Bastardia viscosa (L.) Kunth (Malva bruja o Malvaceae). Rev Cub Quim [online]. 2022, vol.34, n.2, pp. 263-284.  Epub 14-Jun-2022. ISSN 2224-5421.

Bastardia viscosa (L.) Kunth leaf is traditionally used for digestive disorders, but there is no scientific evidence on its physical-chemical quality, so its pharmacognostic characterization was carried out in this work. Macromorphological and micromorphological characteristics, percentages of foreign matter and blackened leaves were determined for three batches of the fresh drug; a drying study was carried out and the percentage of residual moisture and ash was determined for the dry drug; as well as derived extracts the percentage of total solids; according to the Public Health Branch Standard 309/91. The results showed that the best drying method is shade; the macromorphological characteristics coincide with the literature; very low percentages of blackened leaves and foreign matter; percentages of residual moisture and ashes within the permissible limits for unofficial drugs and a higher percentage of total solids in 50 % ethanol.
