Background Many of these plants, have therapeutic effects and can be extracted and used in preparation of drugs, used directly or in combination with other plant extracts for medication which is a common practice in developing counties. Unfortunately, many of those who utilize these plants therapeutically do not have adequate knowledge or training in the safe use of the products. For these reasons, natural plant products need to be standardized and preliminary studies done to evaluate possible risks such as undesirable side effects, overdose and toxicity. Results Ethyl acetate extract of Musa × paradisiaca L shown anticervical carcinoma and anti-malignant melanoma activity in our study. Antioxidant activity demonstrated, that Musa × Paradisiaca L. leaves ethyl extract exhibited % inhibition at absorbance 517 nm with IC50 values = 3.70 to 45.50 at different concentration and compared with ascorbic acid as standard drug. Conclusions The present study indicates the anticancer and antioxidant activity on the basis of biological and phytochemical screening of Musa × paradisiaca L leaves extract. Ethyl acetate extract of leaves was evaluated for its anticancer activity. In vitro anticancer activity of extract were estimated by measuring significant inhibition of HeLa and A375 cell lines by MTT assay. The MTT assay clearly indicates that the inhibition or inhibitory activity of the extract was concentration dependent. Maximum inhibition of cell growth was found at the concentration of 320 µg/ml which was 54.35 and 55.97, respectively for HeLa and A375 cell lines. Therefore, 320 µg/ml concentration of extract was used to study the IC50 value that was calculated as 249.1 and 224.4, respectively. Antioxidant activity demonstrated that, plant extract exhibited percentage inhibition with IC50 values = 3.70 to 45.50 at different concentration and compared with ascorbic acid as standard drug.

A novel ultra-performance liquid chromatographic technique for the estimation of metformin and repaglinide in a API and tablet dosage form. The chromatographic separation was achieved using DIKMA Endoversil (2.1 x 50mm, 1.7µm) column with a mobile phase of phosphate buffer, pH 4.2 and methanol as a mobile phase (38:62) with a flow rate of 0.3 mL/min and the detection wavelength was monitored at 241 nm. The method was validated in accordance with International conference on harmonization guidelines. In this present method metformin was eleued at 0.516 minute and repaglinide was eluted at 1.152 min. Limit of detection was 0.05 μg/ml for metformin and1.152 μg/ml for repaglinide limit of quantification was found 0.5 μg/mL. Calibration curve plots were found linear over the concentration ranges 1-50 μg/mL for both the analytes. The % assay of the marketed dosage form was found 99.45 % for metformin and 97.08 % for repaglinide. The present study approach was found to be effective in the analysis of both analytes in force degradation conditions, because both the analytes has been specifically eluted in presence of other chromatograms. The experiential evidences of all the study results revealed the suitability of the estimation of metformin and repaglinide in API and tablet dosage form.

The current technique was developed to estimate the amount of alectinib present in spiked rabbit plasma using liquid chromatographic mass spectrometry. The liquid-liquid extraction method was used, and chromatographic separation was carried out on a C18 (4.6mm id x 50mm) analytical column with a mobile phase consisting of acetonitrile and water with 0.1% formic acid at a volume ratio of 75:25. Alectinib's product m/z +483.2 (parent) 396.1 (product) and the internal standard m/z +447.5 (parent) 380.3 (product) were both obtained using positive ion mode. The calibration curve was linear from 0.5 to 600 ng/ml. The percentage extraction recovery (98.15% → 98.86%), demonstrated excellent matrix and analyte selectivity (% interference = 0), and satisfactory stability study results in all types (% nominal 94.94% → 99.63%). The intra and interday accuracy with % nominal 97 → 98.8%, precision % CV ≤ 2% in all quality control levels. The rabbit model's pharmacokinetic parameters were examined, and alectinib's area under the curve (AUC 0—∞) was 4269 ± 8.13 hr.ng/ml. The half-life of elimination (t1/2) is 8.52 ± 6.66 hours. The currently established approach was used in rabbit blood samples for pharmacokinetic investigations of commercial formulations since it was thought to be a novel, verified bioanalytical method based on experimental results.

Promising results were produced by the ethanol extract among all the tested extracts that are comparable to the reference standard metformin. The study entrenched the scientific foundation of the benefits of this plant in the medication of diabetes and asserts the use of the root of the plant for treating diabetes as demonstrate in folklore remedies.

The present research provides a new proven ultra-high-performance liquid chromatographic technique for isavuconazole in both bulk and capsule dosage forms. DIKMA Waters BEH C18(50 x 2.6mm, 1.7m) column was used for chromatographic separation. With the isocratic elution mode, a mixture phosphate buffer: methanol 40:60 v/v, was used as the mobile phase, and the eluent was measured at 253 nm using a UV detector. The strategy has been maintained and validated in accordance with the International Conference on Harmonization Guidelines. Stressed deterioration has also been investigated in acidic, alkaline, peroxide, thermal, and photolytic conditions. Isavuconazole was eluted with the retention time 0.861 minute in this procedure. The calibration curve plots for isavuconazole were found to be linear within the concentration ranges of 1-25µg/mL. With a percentage recovery of 100.18 percent, the limit of detection was 0.025g/ml and the value for limit of quantification was 0.50µg/mL. In a force degradation analysis, the current approach was also determined to be stable. Based on the experiential evidence, the present method was found appropriate of isavuconazole estimation in the form of bulk and capsule.
