Resumo: |
The phytotherapy is a form of medicinal therapy that has been grown noticeably over the years, however, despite the broad use of phytomedicines, the quality of these drugs is often poor and questionable. Among the several medicinal plants used as herbal medicine, the Calendula officinalis L. is known for its anti-inflammatory, antiseptic and healing effects. Thus, this present study aimed to enhance and consolidate the use of methods of pharmaceutical technology in the development of phytotherapeutic agents, through the completion of preliminary studies of the planning of a semi-solid formulation phytotherapic containing tincture of Calendula officinalis L., for the quality control of the stages of their development. In the physical characterization and physical chemistry of the dust and tincture of calendula were obtained farmacognóstics specifications consistent with the literature, and to establish the identity of the plant material through the detection of the chemical marker rutin by Thin-Layer Chromatography (TLC). Through the validation of the method, that presented parameters recommended by existing legislation, was given 463 μg/mL of rutin in tincture. The infrared (IR) spectra showed characteristics of rutin in the lyophilised extract, in addition to demonstrate the permanence of these bands after mixing with the excipients of the formulation. The thermoanalytic techniques confirmed the compatibility between the excipients and lyophilisate of calendula extract. In the preliminary assessment of the stability of the gel formulation remained stable during the cycles in greenhouse (45 ± 2 0C) and temperature (25 ± 2 0C). In the preliminary study of the gel, permeation tended to favor the permeation of total flavonoids as rutin for receiving phase. These results demonstrate the importance of employment of protocols for quality control of raw materials plant, besides the establishment of technological methods for the production of phytotherapic. |
