Introduction. The article presents the results of the detection of pharmacologically active secondary metabolites in black crowberry Empetrum nigrum L. using the method of high performance thin layer chromatography (HPTLC).Aim. To show the efficiency of HPTLC for conducting preliminary phytochemical analysis to determine the main groups of metabolites in promising medicinal plant species.Materials and methods. HPTLC analysis was carried out on a CAMAG device (Switzerland), using MERCK HPTLC silica gel 60 F154, 20 × 10 cm plates. For the evaporation of the samples, a Heidolph vacuum rotary evaporator (Germany) was used. The aerial parts (shoots) of Empetrum nigrum were harvested next to St. Petersburg State Chemical and Pharmaceutical University (SPCPU) nursery garden of medicinal plants (Leningrad Region, Vsevolozhsky District, Priozerskoe Highway, 38 km) in August 2019.Results and discussion. In the course of the research, four fractions from the aerial parts of Empetrum nigrum were obtained: hexane, dichloromethane, butanol, and water. Then, these fractions were investigated by HPTLC in two solvent systems – n-butanol : acetic acid : water (BAW) (4 : 1 : 2) and hexane : dichloromethane : methanol (HDM) (1 : 2 : 0.5). After scanning densitometric analysis of the plates eluted in the HDM system, it was revealed, that the hexane and dichloromethane fractions have a similar composition and contain the greatest amount of compounds, compared to the butanol and water fractions, and in the BAW system, it was found, that the butanol fraction contains the greatest variety of metabolites. As a result of UV spectroscopy, it was found, that the main groups of compounds contained in the hexane and dichloromethane fractions are derivatives of chalcones, dihydrochalcones, bibenzyls and 9,10-dihydrophenanthrenes. While in the butanol fraction, the main groups of secondary metabolites were derivatives of flavonoids and tanninsConclusion. The data obtained allow us to note the efficiency, speed and simplicity of HPTLC for conducting preliminary phytochemical analysis to determine the main groups of metabolites of promising medicinal plant species.

Anthocephalus Cadamba

Objective: Anthocephalus cadamba is a traditional medicinal plant which is valued for its benefits in the management of various ailments. The current study was aimed to provide requisite pharmacognostic details and high-performance thin-layer chromatography (HPTLC) fingerprint profile for the roots of A. cadamba. Methods: Pharmacognostic evaluation included examination of morphological and microscopic characters, physicochemical analysis, fluorescence study, preliminary phytochemical analysis, and HPTLC fingerprint. Results: The microscopic studies showed the presence of thick periderm, cortical zone, secondary phloem, and secondary xylem. Microscopic examination of root powder showed abundant fibers and vessel elements. The physicochemical analysis of root powder helped in the assessment of quality control parameters. Fluorescence analysis of root powder imparted characteristic colors on the treatment of the powder with different reagents. Preliminary phytochemical studies reported the presence of alkaloids, saponins, flavonoids, steroids, terpenoids, glycosides, tannins, and other phenolic compounds. The developed qualitative densitometric HPTLC fingerprint can be used as an identifying biochemical marker for ethanol extract of the roots of A. cadamba. Conclusion: The present study provides the information with respect to identification and authentication of crude drug and serves as a reference point for the proper identification of roots of this medicinal plant, thereby contributing to the scientific world of research.

Introduction: Many modern medicines used today based on plants and plant products. Piper betle is generally known as the betle vine, it is an important medicinal and recreational plant. High performance thin layer chromatography (HPTLC) is an advanced powerful analytical method with more separation power, high performance and superior reproducibility than classic thin layer chromatography (TLC). A chromatographic fingerprint of a plant extract is a chromatographic pattern of some common chemical constituents of pharmacologically active and/or chemical characteristics. Chromatographic fingerprints are useful in authentication and identification of plant. Objectives:  Objectives of present research was to establish HPTLC fingerprinting of methanolic extract of Piper betle L. leaves. Materials and Methods: Methanolic extract of Piper betle leaves was prepared using soxhlet apparatus. HPTLC studies were performed using a CAMAG HPTLC system equipped with automatic TLC sampler-4 (ATS 4), TLC scanner 4, and vision CATS 3.0 software. Results: The study revealed the presence of alkaloids with Rf value 0.65, flavonoids with Rf values 0.19, 0.29, 0.72, 0.95., and phenolic compound with Rf value 0.7. Conclusion: The HPTLC fingerprinting profile developed for the methanolic extract of Piper betle L. leaves will help in proper identification of the plant.Piper betle

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.

  Objective: The objective of this study was to quantify the luteolin content present in the extracts from different aerial plants (leaves, stem, and inflorescence) of Heteropogon contortus through high-performance thin-layer chromatography.Methods: The chromatographic fingerprint analysis of the different plant extracts has been developed using optimized mobile phase toluene: ethyl acetate: formic acid (5:5:0.7 v/v) and the developed plate is derivatized with freshly prepared anisaldehyde-sulfuric acid. Then, the plate is heated at 110–120°C. The plate is scanned for densitometry measurements and to record the overlay spectra at 366 nm absorbance/reflectance wavelength. Quantification of luteolin marker compound in different extracts of H. contortus is estimated using 2–12 ng/spot.Results: The yellow colored bands appearing on the chromatogram confirm the presence of luteolin marker compound in the different plant samples of H. contortus. Further, the presence of the luteolin marker is confirmed by comparing the Rf values (0.21) of the standard and the samples and from densitometry measurements by scanning the plate at 366 nm absorbance/reflectance. Line-to-line overlay spectra are obtained.Conclusion: From this, it is concluded that leaf sample of H. contortus contains maximum amount of luteolin, i.e., 37.13 ± 0.11 mg/g of dry wt. than inflorescence (1.60 ± 0.013 mg/g of dry wt.) and stem (0.53 ± 0.014 mg/g of dry wt.). The leaves are good source of luteolin and can be used as an alternate natural source to synthesize herbal drugs to cure cancer, hypertension, and inflammatory diseases.
