The purpose of this study was to develop and validate a simple, sensitive, accurate, and reproducible reverse phase high performance liquid chromatography (RP-HPLC) method for simultaneous estimation of amlodipine besylate and lisinopril in a Tablet dosage form. The chromatographic measurement was performed on a Phenomenex C18 (250 × 4.6 mm, 5um) column with an optimised Acetate buffer mobile phase: Methanol (65:35). The flow rate was one ml/min, and the detecting wavelength was 221 nm. Triethanolamine was used to adjust the pH to 5. In the concentration range of 4-20 ug/ml, amlodipine besylate and lisinopril showed a linear response of the suggested approach. The correlation coefficients ('r' values) for amlodipine besylate and lisinopril were 0.9998 and 0.9995, respectively, and the retention times were 3.279 for amlodipine besylate and 6.124 for lisinopril, respectively. The developed chromatographic technique was validated for specificity, linearity, precision, accuracy, LOD, and LOQ using ICH Q2(R1) criteria. The analysis results have been validated in accordance to ICH guidelines

“…In terms of the potential health‐enhancing properties, some antioxidant properties and biological activities, commonly related to the pigment profile, have been ascribed to these edible flowers. Among them, it is noteworthy the antimicrobial activity of the leaves of Tibouchina candolleana (Durães Vieira et al ., 2019), antioxidant and anti‐inflammatory activities of Tibouchina pulchra and Tibouchina granulosa (Esposito & Domingos, 2014; Sobrinho et al ., 2017), and anti‐inflammatory activities of Tibouchina urvilleana (Pérez‐Castorena, 2014; Gowthami & Naga Lakshmi, 2021). Further health‐related properties as anti‐leishmanial, anti‐inflammatory, and antimicrobial activities were ascribed to Tibouchina paratropica (Tracanna et al ., 2015) and antioxidant activity and cytotoxicity in THP‐1 cell parasitic activity to Tibouchina francavillana and Tibouchina lhotzkyana (Bomfim et al ., 2022).…”

Summary A purification and fractionation process of the edible flowers of Tibouchina mollis and Tibouchina urvilleana followed by the first attempt to the anthocyanin and flavonol characterisation and identification by UHPLC‐DAD‐ESI‐MS were developed. T. urvilleana exhibited a higher monomeric anthocyanin content, mainly due to the presence of the 3‐O‐(6′‐p‐coumaroyl)‐glucoside derivatives of malvidin and petunidin. Quercetin‐3‐O‐hexoside was the major flavonol identified in T. urvilleana, and the lack of myricetin derivatives was also exhibited. The anthocyanin and flavonol profile of T. mollis was more miscellaneous, characterised by the occurrence of cyanidin‐3‐O‐glucoside followed by the 3‐O‐(6′‐p‐coumaroyl)‐glucoside and 3‐O‐glucoside derivatives of malvidin and petunidin as anthocyanins, and myricetin, quercetin, and 3‐O‐hexosides of kaemperol and quercetin as flavonol compounds. Therefore, the anthocyanin and flavonol profile, through a process based on purification and fractionation, could be a useful tool to ensure the authenticity of the Tibouchina. Furthermore, the purification process made the antioxidant activity increase, which is greatly correlated to the reduction capacity.
