Ursolic acid (UA) is the most important bioactive phytoconstituent of Eucalyptus × hybrida Maiden leaves and exhibits anticancer, antimutagenic, anti-inflammatory, antioxidative, and antiprotozoal activities. In this study, microwave-assisted extraction technique was employed for rapid isolation of UA from the leaves of Eucalyptus × hybrida and(More)
Arjunic acid and arjunolic acid are main bioactive components of Terminalia arjuna stem bark and reported for various biological activities. In this study, microwave-assisted extraction (MAE) of arjunic and arjunolic acid from stem bark of T. arjuna was investigated with developed and validated HPLC-PDA method, which resulted in the isolation of a novel(More)
Two spectrophotometric methods have been developed for the simultaneous determination of diloxanide furoate and tinidazole in combined dosage formulations without prior separation. The first method is based on the measurement of the absorbance of a methanolic solution of the sample at 259 and 311 nm and application of a simplified Vierordt equation for the(More)
Two spectrophotometric methods have been developed for the simultaneous determination of chlorzoxazone and acetaminophen in their combined dosage forms. No preliminary separation step is required in either method. The first, an absorbance ratio technique using the isoabsorptive point as one of the wavelengths, together with "Q curve" analysis gives accurate(More)
A simple, very fast, precise and accurate reverse phase ultra performance liquid chromatographic method was developed for the determination and validation of topotecan hydrochloride in bulk and injection dosage form. A Waters BEH C18, 50×2.1 mm, 1.7 μm particle size column in gradient mode was used with mobile phase comprising of 0.1% v/v orthophosphoric(More)
