A reverse phase HPLC method with UV detection has been developed and validated in order to quantify plumbagin, the bioactive marker of the roots of P. indica and P. zeylanica. A quantitative HPTLC method was also developed using hexane: ethyl acetate (8:2) as the mobile phase. The plumbagin content in the roots were determined using both the methods. P. indica was found to contain significantly...

background and objectives: attenuated total reflectance-inferared (atr-ir) spectra can be used as a non-invasive fingerprinting approach in quality control of herbal samples. methods: twenty versatile herbal samples were subjected to attenuated total reflectance-inferared (atr-ir) spectroscopy followed by different clustering methods in order to determine by which method more reasonable classif...

Abstract Background The analysis of myo‐inositol phosphates (InsP x ) released by phytases during phytic acid degradation is challenging and time‐consuming, particularly in terms sample preparation, isomer separation, detection. However, a fast robust method crucial when screening for protein engineering approaches, which result large number samples, to ensure reliable identification promising ...

FeiYangchangweiyan capsule (FY capsule), a traditional Chinese medicinal preparation consisting of three medicinal herbs, has been used to treat bacterial dysentery, acute, and chronic gastroenteritis for several decades. In this study, a novel, convenient, accurate, and valid method was developed by using high-performance liquid chromatography (HPLC) coupled with diode array detection...

Abstract Pressurized planar electrochromatography (PPEC) of dansyl (DNS) derivatives amino acids in normal- and reversed-phase systems is presented. The results have been obtained for mobile phases with different acetonitrile (ACN) concentrations (0–85%). data show differences separation selectivity between high-performance thin-layer chromatography (HPTLC) PPEC systems. These originate from th...

In Valencia Region (Spain), some wild and cultivated sages are used for medicinal purposes. Among them, Salvia officinalis subsp. lavandulifolia (SL) is widely employed and known for production of Spanish sage oil and herbal products. Nevertheless, it shares the market with S. blancoana subsp. mariolensis (SB) and, to a lesser extent, with their hybrid S. x hegelmaieri (SH). The knowledge on th...
