Comparison of the Phenolic Component Profiles of Skullcap (Scutellaria lateriflora) and Germander (Teucrium canadense and T. chamaedrys), a Potentially Hepatotoxic Adulterant Profile Differences of Skullcap and Germanders
Introduction – Scutellaria lateriflora, commonly known as skullcap, is used as an ingredient in numerous herbal products. Unfortunately, it has occasionally been adulterated with Teucrium canadense or T. chamaedrys, commonly known as germander, which contains potentially hepatotoxic diterpenes. Chromatographic profiles of the phenolic components provide a means of distinguishing between these p...
متن کاملQuantitative Estimation of Efavirenz by High Performance Thin Layer Chromatography
A simple, accurate, and precise HPTLC method has been developed and validated for the estimation of efavirenz from bulk drug and capsule formulations. The separation was achieved on TLC plates using an appropriate solvent system. The spots so developed were densometrically scanned at 247 nm. The linearity of the method was found to be within the concentration range of 1-40 μg/ml. The validation...

متن کاملExtract of Scutellaria baicalensis inhibits dengue virus replication
BACKGROUND Scutellaria baicalensis (S. baicalensis) is one of the traditional Chinese medicinal herbs that have been shown to possess many health benefits. In the present study, we evaluated the in vitro antiviral activity of aqueous extract of the roots of S. baicalensis against all the four dengue virus (DENV) serotypes. METHODS Aqueous extract of S. baicalensis was prepared by microwave en...
متن کاملQuantitation of artemether in pharmaceutical raw material and injections by high performance liquid chromatography
The quantitation of artemether in both pharmaceutical raw material and injections was carried out by high performance liquid chromatography (HPLC) with ultraviolet detection. A Zorbax C18 column (150 x 4.6 mm; 5 μm), at 30 °C, and a mobile phase composed of acetonitrile and water (70:30), at a flow rate of 1ml/min, were used. The detection wavelength was 216 nm and the injection volume was 20 μ...
