Abstract The use of herbs as medicine is an ancient form of healthcare known to mankind. Standardization of herbal medicines is however a challenging task and is the major bottleneck in their acceptance as the primary therapeutic option. The aim of this study was to develop and validate a simple, rapid HPLC method for standardizing the mixture of extracts of three Medhya Rasayanas (neurotonic), Convolvulus pluricaulis, Withania somnifera and Bacopa monnieri. Simultaneous estimation of the respective bioactive markers of these plants viz., scopoletin, withaferin A, bacoside A 3, bacopaside II, jujubogenin and bacosaponin C has been reported for the first time. The method was developed using Waters Hybrid X-Bridge shield with BEH technology 2.5 μm, 4.6 × 75 mm column and validated according to ICH guidelines. The 20 minutes run time makes the method eco-friendly. The method was linear over a range of 12.5–400 ng/10 μL for scopoletin and 62.5–2,000 ng/10 μL for withaferin A, bacoside A 3, bacopaside II, jujubogenin and bacosaponin C with detection limits of 8.0, 48.3, 30.4, 40.7, 15.6 and 18.9 ng/10 μL and quantification limits of 24.5, 146.5, 92.2, 123.4, 47.4 and 57.4 ng/10 μL, respectively. The correlation coefficient for each analyte was >0.999. The intra-day and inter-day precision was <2%. These results confirmed the precision, accuracy and robustness of the proposed method.

Development And Validation

A simple, accurate, precise, robust stability indicating RP-HPLC method was developed and validated for simultaneous estimation of berberine and curcumin in an ayurvedic formulation. The two markers were resolved using a C-18 column using as the mobile phase methanol: water (pH 3 adjusted using acetic acid) in the ratio 75:25 V/V at a flow rate of 1mL/min. Retention times of berberine and curcumin were 2.58 ± 0.2 min and 8.5 ± 0.2 min, respectively at 358 nm. Linear response was observed in the concentration range of 2 – 8 ppm for berberine and 5 – 40 ppm for curcumin, with correlation coefficient (r2) of 0.994 and 0.998 for berberine and curcumin, respectively. The developed method was applied for quantitation of markers in marketed and in-house formulations of Gruhadhoomadi Churna. This method can also be used to evaluate formulations containing berberine and curcumin as markers, thus conforming to the need of ensuring quality and safety of herbal medicines.

Development And Validation

Brahmi (Bacopa monnieri) has been used by Ayurvedic medical practitioners in India for almost 3000 years. The pharmacological properties ofBacopa monnieriwere studied extensively and the activities were attributed mainly due to the presence of characteristic saponins called “bacosides.” Bacosides are complex mixture of structurally closely related compounds, glycosides of either jujubogenin or pseudojujubogenin. The popularity of herbal medicines and increasing clinical evidence to support associated health claims require standardisation of the phytochemical actives contained in these products. However, unlike allopathic medicines which typically contain a single active compound, herbal medicines are typically complex mixtures of various phytochemicals. The assay for bacosides in the British Pharmacopoeia monograph forBacopa monnieriexemplifies that only a subset of bacosides present are included in the calculation of total bacosides. These results in calculated bacoside values are significantly lower than those attained for the same material using more inclusive techniques such as UV spectroscopy. This study illustrates some of the problems encountered when applying chemical analysis for standardisation of herbal medicines, particularly in relation to the new method development and validation of bacosides from KeenMind.

Withania somnifera (L.) Dunal (Solanaceae) commonly known as ashwagandha, is an important plant in Ayurveda and is believed to increase longevity and vitality. The root is considered to be the medicinally important part of the plant as per classical texts and accordingly is the subject of most Pharmacopeial monographs. The aerial parts, being less expensive, are sometimes mixed with roots to prepare “standardized” extracts of W. somnifera, and in cases with false declaration of plant part used as roots on the certificate of analysis. The present study described a new, simple, accurate, and precise HPLC method for the simultaneous determination of flavonoid glycosides as unique constituents of the aerial parts, being absent in roots of the plant. The RSD for intra- and interday analyses was less than 2.5% and the recovery was 90–108%. The method was used to analyze samples of roots and aerial parts of the plant collected from India and Egypt. The samples of commercially available extracts of W. somnifera were also analyzed and many samples were found to contain flavonoid glycosides indicating a possible undeclared use of aerial parts in the extracts derived from roots in commercial practice.

Dextromethorphan Hydrobromide

The present work describes a validated reverse phase high performance liquid chromatography (RPHPLC) method for simultaneous estimation of dextromethorphan hydrobromide and quinidine sulphate in pharmaceutical dosage from. The drugs were resolved using Hemochrom Intsil C18-5U column (250×4.6) mm in isocratic mode with mobile phase methanol: water (0.08% diethylamine, 0.02% of glacial acetic acid and pH 4.4 adjusted with orthophosphoric acid) in the ratio of 70:30 V/V at a flow rate of 1.0 mL/min. Retention time of dextromethorphan hydrobromide and quinidine sulphate were 4.9±0.2 and 3.6±0.2, respectively, at 292nm. The above mentioned method was validated as per International Conference on Harmonization (ICH) guidelines. Linear responses were obtained in concentration ranges of 5-35 μg/mL for dextromethorphan hydrobromide and 4-16 μg/mL for quinidine sulphate, with correlation coefficient (r2) of 0.999 for both the drugs. A simple, selective, accurate, precise, robust and reliable RP-HPLC method thus developed and validated for simultaneous estimation of dextromethorphan hydrobromide and quinidine sulphate.

The present research work illustrates the development and validation of RP HPLC method for simultaneous estimation of tenofovir disproxil fumarate, emtricitabine and rilpivirine hydrochloride in bulk and formulated in a pharmaceutical dosage form as a nanosupension. Antiretroviral drug treatment is the primary line of therapy for treating HIV. The multicomponent system formulated as a nanosuspension evidenced increased hydrophilicity, potency and decreased side effects. The separation was carried out by using efficient BDS hypersil C18 HPLC column with empower software. Combination method of Precipitation—ultrasonic homogenization was used for the preparation of the nanosuspension. The mobile phase used was methanol, water, acetonitrile (80:13.4:6.6) v/v and flow rate 1mL /min. The developed method was thus validated as per ICH guidelines for various parameters whose results advocated the reliability of the method. The results for parameters viz. retention times of tenofovir disproxil fumarate, emtricitabine and rilpivirine were 3.09 min, 2.78 min and 3.68 min, linearity range was between 7.5-90, 5-60, 0.625-7.5µg/mL, respectively. Thus the new RP-HPLC method is optimum, reliable and can be used for the simultaneous estimation of tenofovir disproxil fumarate, emtricitabine and rilpivirine hydrochloride.
