Moringa oleifera and chywanprash are two main nutraceuticals used worldwide because of their large medicinal application. The quality of these nutraceutical products is in question, especially due to the inorganic contaminants like heavy metals. In the present study, six Moringa herbal powder and five chywanprash samples were collected in India and further analyzed for As, Cd, Hg, and Pb. All samples were microwave digested and analyzed by ICP-MS. In Moringa As, Cd, Hg and Pb were found in the range of 0.027-5.264 µg/mL, 0.014-0.039 µg/mL, 0.049-45.225 µg/mL and 0.323-12.487 µg/mL respectively. In chywanprash As, Cd, Hg and Pb were found in the range of 0.012-0.021 µg/mL, 0.004-0.029 µg/mL, 0.01-0.103 µg/mL and 0.06-0.171 µg/mL respectively. The concentration of these heavy metals were found to be more than the maximum permissible limit given by the WHO for herbal medicines. Hence strong regulatory guideline needs to be prepared to improve quality of...

Aim: The present study was undertaken to screen the phytochemicals present in fruits of Grewia tiliaefolia and to evaluate the potential role of these fruits in the amelioration of cisplatin-induced nephrotoxicity in male Albino rats. Materials and methods: Ethanol extract of Fruits of Grewia tiliaefolia was prepared by hot extraction method. The prepared ethanol extract was subjected to preliminary phytochemical evaluation followed by TLC, HPTLC, HPLC and GC-MS analysis. The nephroprotective potential of the extract was screened at 200 and 400mg/kg b. w. in both curative and prophylactic regimens in male Albino rats. Nephrotoxicity was induced by single intraperitoneal injection of cisplatin at a dose of 5 mg/kg b.w. The nephroprotective activity was assessed by determining serum markers, urinary parameters, lipid peroxidation and antioxidant levels and his to pathological studies in renal tissue. Results: Upon preliminary phytochemical screening, the ethanol extract showed the presence of Proteins, flavonoids, Tannins, Terpenoids. HPTLC analysis resulted in a fingerprint of extract showing the presence of 14 compounds. TLC and HPLC revealed the presence...

Background: Dolutegravir and Rilpivirine are two antiretroviral drugs that have been approved for the treatment of HIV Infection. An error-free, accurate, precise and valid reverse-phase liquid chromatography method was developed for the quantitation of Dolutegravir and Rilpivirine in its bulk form as well as in combined dosage form by forced degradation studies. Methods: Chromatographic separation of these two drugs Dolutegravir and Rilpivirine, was achieved with an INERTSIL ODS C18 (250 × 4.6 mm, 5 μm) reverse-phase analytical column with a 10 min analytical run time using a mixture of 0.1% OPA: Acetonitrile in the ratio of (60:40 v/v) as mobile phase. The mobile phase was streamed at a flow rate of 1.0 mL min-1 with a column temperature of 250 °C and detection wavelength was carried out at 230 nm. The retention time was found to be 3.4 min for Dolutegravir and 4.3 min for Rilpivirine. Results: The linearity limit of Dolutegravir and Rilpivirine was found to be in the range of 0.999 and 0.999. The method validation was...

Zingerone is an active phenolic acid and the least pungent component of Zingiber officinale. It is known to exhibit different pharmacological properties which include anti-inflammatory, antioxidant, anticancer and antimicrobial activities. But, so far there has been no information available on the role of zingerone in experimental breast carcinogenesis. The objective of this experiment is to untwine the anticancer qualities of zingerone against dimethylbenz (a) anthracene (DMBA)-incited mammary carcinogenesis. To achieve this goal, female Sprague-Dawley rats were arbitrarily classified into six groups. Group 1 was notified as the control, groups 2-5 were given a single dose of DMBA (25 mg/kg b.wt, subcutaneously) in the 4th week. Along with DMBA, groups 3 (initium), 4 (post-initium) and 5 (entire period) rats received zingerone (20mg/kg b.wt. p.o) every day in different time periods during the experimental period of 16 weeks. Group 6 rats received 20 mg/kg b.wt. of zingerone alone. Cancer-bearing animal mammary tissue when evaluated by western blot showed increased immune expression patterns of ER, PR, HER2/ neu, cyclin D1 and also...

One of the major barriers in the development of oral dosage form is poor solubility. Poor water solubility obstructs drug bioavailability and decreases its pharmaceutical development. Many drugs are in the pipeline to enhance solubility to formulate dosage form to be taken by the most preferred route of administration that is the oral route. Etodolac is nonsteroidal anti-inflammatory drug having a wide spectrum of activities but belongs to BCS class II. The attempt has been made in this work to improve solubility by forming ternary inclusion complexes of Etodolac with PVP K30 and β-Cyclodextrins. The ternary inclusion complexes were prepared by the physical mixing method and kneading method. The prepared complexes were analyzed by different analytical techniques comprising differential scanning calorimetry, infrared spectroscopy and solubility study. Special emphasis was given on the solubility evaluation of drugs and complexes. Based on observations and results, one can easily conclude about the usefulness of the complexation technique for the enhancement of...
