Periploca aphylla (PA), an interesting Saudi medicinal plant, is used in folk medicine to treat urticaria, cerebral fever, tumors, and swelling. To prove its use in folk medicine, two different extracts from the aerial parts of the plant: chloroform P-1, and n-butanol P-2 were subjected to biological assays to screen peroxisome proliferator-activated receptors (PPARα and PPARγ) agnostic, anti-inflammatory, antioxidant, cytotoxic, and estrogenic activities. In addition, five bioactive secondary metabolites were isolated from the aerial parts of the plant: rutin, chlorogenic acid, caffeic acid, ursolic acid, and stigmasterol. P-1 and P-2 decreased cellular oxidative stress by 47.0% and 62.0%, respectively, compared to the standard drug quercetin, while one of the compounds rutin PA-1 isolated from P-1 extract and significantly decreased cellular oxidative stress by 67.0% compared to quercetin (75.0%). P-1 and P-2 also significantly activated PPARγ agnostic. P-1 and P-2 did not inhibit nuclear factor kappa B and inducible nitric oxide synthase activity and showed no cytotoxic or estergenic effects on four human cancer cell lines. In this study, both extracts were standardized using high-performance thin-layer chromatography (HPTLC). RP-HPTLC showed sharp and compact bands of rutin (Rf = 0.09), caffeic acid (Rf = 0.25), and chlorogenic acid (Rf = 0.39) scanned at λmax = 340 nm using the water: methanol (60:40 v/v) mobile phase. At λmax = 539 nm ursolic acid (Rf = 0.20) and stigmasterol (Rf = 0.48) were scanned using the chloroform: methanol (98:2 v/v) as NP-HPTLC mobile phase. Therefore, the developed RP- and NP-HPTLC systems are a precise, sensitive, and specific analytical tool for the quantification of compounds isolated from PA, which can be used as phytomarkers for taxonomical identification and assessment of PA.

Thymus species belong to the Lamiaceae family, of which 18 species in the flora of Iran, 6 are endemic to Iran. In the current research, high-performance thin-layer chromatography (HPTLC) technique as an easy, fast, reproducible, and low-cost method was used for the determination of rosmarinic acid and caffeic acid in Thymus lancifolius (T. lancifolius) and two species of Thymus daenensis (T. daenensis) from Iran. Toluene-ethyl acetate-formic acid with a ratio of 67.72-22.90 and 9.38% was selected as the mobile phase of rosmarinic acid, and ethyl acetate-methanol-formic acid-water with a ratio of 85-8-2 and 5% was designated as the mobile phase of caffeic acid. The highest and lowest amount of rosmarinic acid was observed for T. daenensis 1 (10.54±0.12 mg/g) and T. lancifolius (0.46±0.01 mg/g), respectively. The amount of rosmarinic acid for T. daenensis 2 was obtained as 7.85±0.02 mg/g for each of the dried plants. In the following, HPTLC analysis of caffeic acid for T. daenensis 1, T. daenensis 2, and T. lancifolius was acquired amounts of 0.78±0.007, 0.13±0.007, and 0.26±0.007 mg/g for each of dried plants, respectively. Therefore, regarding the special effects of phenolic acids and properties of the Thymus genus, the acquired results are suitable for application in pathogenic research, infections, immunology diseases, and evaluation of the antioxidant activity.

Abstract Ocimum sanctum (family Lamiaceae) is a reputed drug of Ayurveda, commonly known as Tulasi. Inthe present work, we quantified 4 marker compounds, viz., eugenol, luteolin, ursolic acid, and oleanolic acid, from the leaf of green and black varieties of O. sanctum using high-performance thin-layer chromatography (HPTLC) with densitometry. The methods were found to be precise, with relative standard deviation (RSD) values for intraday analyses in the range of 0.52 to 0.91%, 0.77 to 1.29%, 0.11 to 0.16%, and 0.34 to 0.42% and for interday analyses in the range of 0.73 to 0.96%, 1.02 to 2.08%, 0.11 to 0.12%, and 0.39 to 0.64% for different concentrations of eugenol, luteolin, ursolic acid, and oleanolic acid, respectively. Instrumental RSD values were 0.24, 0.39, 0.21, and 0.18% for eugenol, luteolin, ursolic acid, and oleanolic acid, respectively. Accuracy of the methods was checked by conducting a recovery study at 3 different levels for the 4 compounds, and the average recoveries were found to be 99.73, 99.3, 100.58, and 100.57%, respectively. Eugenol content ranged from 0.175 to 0.362% (w/w) and luteolin from 0.019 to 0.046% (w/w) in the samples analyzed. Green variety was found to contain higher amounts of ursolic acid [0.478 and 0.348% (w/w), from Sources 1 and 2, respectively] than the black variety [0.252 and 0.264% (w/w) from Sources 1 and 2, respectively]. Black variety had 0.174 and 0.218% (w/w) of oleanolic acid from Sources 1 and 2, respectively, while it was not detected in the green variety. Ursolic acid and oleanolic acid ran at the same Rf value and could not be resolved in several solvent systems tried. However, we observed that only ursolic acid gave yellow fluorescence under 366 nm ultraviolet light after derivatization with anisaldehydesulfuric acid reagent. The HPTLC-densitometry methods for the quantification of the 4 markers in O. sanctum leaf will have the applicability in quality control.

Abstract Background: Alpinia officinarum Hance (ginger family) is an important Chinese medicine, especially in Southern China. Objective: A simple and effective high-performance thin-layer chromatography coupled with 2, 2-diphenyl-1-picrylhydrazyl bioautography (HPTLC-DPPH) and electrospray ionization quadrupole time-of-flight tandem mass spectrometry (ESI-Q-TOF-MS/MS) method was developed for the bioactivity-based quality control of A. officinarum. Methods: The HPTLC-DPPH and ESI-Q-TOF-MS/MS were applied for the analysis of different parts of A. officinarum after using methanol extraction for 23 batches of taproot, four batches of aerial, and three batches of fibril parts. Results: The systematic evaluation showed that similar components in taproot and aerial parts make the major antioxidant activity. However, based on our evaluation, the antioxidant ability of the aerial parts is lower than the taproot parts. There is also a significant difference (P < 0.05) between taproot and fibril parts of the root. The chemical structures of compounds with the antioxidant capacity were tentatively identified as 5R-hydroxy-7-(4-hydroxy-3-methoxyphenyl)-1-phenyl-3-heptanone (band 1), kaempferide (band 2), and galangin (band 3) based on ESI-Q-TOF-MS/MS analytical results and further confirmed by standards. Conclusions: This identification indicated that two flavonoid compounds and one diarylheptanoid compound possessed high potentials to be used as the antioxidant biomarkers for the quality control of A. officinarum. Highlights: The comparison of different parts could be considered as guidelines for the usage of A. officinarum.

Abstract This paper describes validated high-performance liquid chromatography (HPLC) and high-performance thin-layer chromatography (HPTLC) methods for the simultaneous estimation of pantoprazole (PANT) and domperidone (DOM) in pure powder and capsule formulations. The HPLC separation was achieved on a Phenomenex C18 column (250 mm id, 4.6 mm, 5 μm) using 0.01 M, 6.5 pH ammonium acetate buffer-methanol-acetonitrile (30 + 40 + 30, v/v/v, pH 7.20) as the mobile phase at a flow rate of 1.0 mL/min at ambient temperature. The HPTLC separation was achieved on an aluminum-backed layer of silica gel 60F254 using ethyl acetatemethanol (60 + 40, v/v) as the mobile phase. Quantification was achieved with ultraviolet (UV) detection at 287 nm over the concentration range 400-4000 and 300-3000 ng/mL with mean recovery of 99.35 ± 0.80 and 99.08 ± 0.57% for PANT and DOM, respectively (HPLC method). Quantification was achieved with UV detection at 287 nm over the concentration range 80-240 and 60-180 ng/spot with mean recovery of 98.40 ± 0.67 and 98.75 ± 0.71% for PANT and DOM, respectively (HPTLC method). These methods are simple, precise, and sensitive, and they are applicable for the simultaneous determination of PANT and DOM in pure powder and capsule formulations.

AbstractThe problems with separation of amino acid mixtures in reversed-phase mode are the result of their hydrophilic nature. The derivatisation of the amino group of mentioned above solutes leads to their solution. For this purpose, 9-fluorenylmethoxycarbonyl chloroformate (f-moc-Cl) as the derivatisation reagent is often used. In our study, the separation of some f-moc- amino acid derivatives (alanine, phenylalanine, leucine, methionine, proline and tryptophan) with the use of micellar systems of reversed-phase high-performance thin-layer chromatography (HPTLC) and pressurized planar electrochromatography (PPEC) is investigated. The effect of surfactant concentration, its type (anionic, cationic and non-ionic) and mobile phase buffer pH on the discussed above solute migration distances are presented. Our work reveals that the increase of sodium dodecylsulphate concentration in the mobile phase has a different effect on solute retention in HPTLC and PPEC. Moreover, it also affects the order of solutes in both techniques. In PPEC, in contrast to the HPTLC technique, the mobile phase pH affects solute retention. The type of surfactant in the mobile phase also impacts solute retention and migration distances. A mobile phase containing SDS improves system efficiency in both techniques. Herein, such an effect is presented for the first time.
