This is the first report on the phytochemistry of Nunavik (Québec, Canada) populations of Rhodiola rosea L., a medicinal plant widely used in Eurasia as a tonic and adaptogen. The wild harvested rhizome of the Nunavik populations contained the marker phytochemicals (salidroside, rosarin, rosavin and rosin) reported in authentic Eurasian material, although in lesser amount. Phytochemical profiling by HPLC of the Nunavik populations also showed the presence of new marker compounds not found in the Eurasian material. For quantitative analysis of the phytochemicals, method validation was undertaken, and the marker phytochemicals were measured in the rhizome, leaf, stem, and seeds. The rhizome showed the highest amount of salidroside and rosavins, as well as the highest total phytochemical content. Consequently, the rhizome remains the most medicinally valuable part of R. rosea.

Solanum glaucophyllum Desf. (Solanaceae) is traditionally used for curing several health conditions in both human and domesticated animals. There is no data available regarding pharmacognostic standardization and pharmacological activity of this less known medicinal plant. Therefore, the aim of the present work is to prepare pharmacognostic fingerprints of crude drugs obtained from the leaf and stem parts of S. glaucophyllum. Apart from this detailed phytochemical analysis, antioxidant and antimicrobial studies have also been carried out. Pharmacognostic study revealed that the leaves are amphistomatic and stomata are strictly of anisocytic type. Values of stomatal index, palisade ratio, ash content of the investigated parts are found distinct and can be used as pharmacognostic standards for evaluation of crude drugs of this medicinal plant. Phytochemical studies of the leaf and stem parts indicated that phenolics, flavonoids, tannins and alkaloids are present in quite impressible amount. Curcumin content in stem was found very high through HPLC analysis. In DPPH radical scavenging assay, the stem part showed significant antioxidant potential. Ethanol extract of stem produced maximum inhibition zone (11mm) against Pseudomonas aeruginosa at the concentration of 50 mg/ml among five test microorganisms. Some pharmacognostic features recorded in this study as diagnostic ones will help in proper identification of this ethnomedicinal plant in its fresh as well as dried form. On the other hand preliminary phytochemical, antioxidant and antimicrobial studies highlight the S. glaucophyllum as a promising candidate for bioprospecting.

Pharmacological Properties

Background:Tamarix Articulata (T. articulata), commonly known as Tamarisk or Athal in Arabic region, belongs to the Tamaricaece species. It is an important halophytic medicinal plant and a good source of polyphenolic phytochemical(s). In traditional medicines, T. articulata extract is commonly used, either singly or in combination with other plant extracts against different ailments since ancient times.Methods:Electronic database survey via Pubmed, Google Scholar, Researchgate, Scopus and Science Direct were used to review the scientific inputs until October 2018, by searching appropriate keywords. Literature related to pharmacological activities of T. articulata, Tamarix species, phytochemical analysis of T. articulata, biological activities of T. articulata extracts. All of these terms were used to search the scientific literature associated with T. articulata; the dosage of extract, route of administration, extract type, and in-vitro and in-vivo model.Results:Numerous reports revealed that T. articulata contains a wide spectrum of phytochemical(s), which enables it to have a wide window of biological properties. Owing to the presence of high content of phytochemical compounds like polyphenolics and flavonoids, T. articulata is a potential source of antioxidant, anti-inflammatory and antiproliferative properties. In view of these pharmacological properties, T. articulata could be a potential drug candidate to treat various clinical conditions including cancer in the near future.Conclusion:In this review, the spectrum of phytochemical(s) has been summarized for their pharmacological properties and the mechanisms of action, and the possible potential therapeutic applications of this plant against various diseases discussed.

The use of traditional medicines holds a great promise as an easily available source as effective medicinal agents to cure a wide range of ailments among the people particularly in tropical developing countries like India. The present study investigates the qualitative and quantitative analysis of the major bioactive constituents of N. crenulata leaf extracts. The extractive values of aqueous, acetone and chloroform extracts were found to be 11.34, 4.24 and 6.06 respectively. Qualitative phytochemical analysis of these three solvent extracts confirm the presence of Alkaloids, Saponins, Flavonoids and Phenolic compounds in all the three extracts; however, these phytochemicals were more significant in aqueous extract. Quantitative analysis was carried out using TLC method by different solvent system. Amongst various solvent systems, Butanol: acetic acid: water (9: 0.9: 0.1 v/v/v) shows maximum resolution and number of spots produced at long UV (365 nm) and under iodine vapours. The TLC chromatograms constituted different coloured phytochemical compounds with different Rf values. It can be conveniently used to evaluate the quality of different area samples. This indicates that the leaves can be useful for treating different diseases because the therapeutic activity of a plant is due to the presence of particular class of compounds and thus can serve as potential sources of useful drugs in future.

Propolis is one of the natural products produced by kelulut bees and is still not widely used. The type of stingless bee that is the prima donna in the community is Heterotrigona itama. This study aims to determine the phytochemical content of the n-hexane fraction of Heterotrigona itama bee propolis collected from Kutai Kartanegara, East Kalimantan. The n-hexane fraction was obtained from the methanol extract of H. itama propolis by the liquid-liquid partition method. After obtaining the n-hexane fraction, the research continued with a qualitative phytochemical test to identify the compound and determine total phenolic. Antibacterial activity was determined by the agar well diffusion method with a serial concentration in Escherichia coli bacteria. Qualitative phytochemical analysis in the form of color changes showed that the n-hexane fraction of H. itama propolis contained flavonoids, alkaloids, saponins, and tannins. Based on the results, the total phenolic content of the n-hexane fraction sample was 490 mgGAE/100 g. It caused the n-hexane fraction to have lower phenolic content than the methanol extract (792 mg GAE100 g). Furthermore, this result indicated that the non-polar fraction was not substantial enough to extracted phenolic compounds. It correlated to the antibacterial activity of the n-hexane fraction, which was very weak (2  mm ± 1.5) at  200µg/mL concentration.
