Abstract Introduction: For generations, many plants were extracted to find drugs and to discover novel and new chemical structures from extracts. Maerua oblongifolia (Forsk.) A. Rich, “Sangganaa” in Dawuro language is a locally threatened traditional medicinal plant, which is traditionally used to treat diarrhea. The present study aimed to check the chemical contents of the different plant parts for possible shifting of the extensive use of the root to other parts of the plant.Methods: Phytochemical screening tests were carried out by standard procedures to investigate various classes of secondary metabolites. Roots, root bark, stem bark, and leaves were extracted by maceration in aqueous and ethanol to get crude extracts. Antibacterial effect of extracts against Escherichia coli and Salmonella thypi was evaluated by the disc diffusion method. Results: The phytochemical analysis showed the presence of alkaloids, saponins, tannins, phenols, carbohydrates, and proteins in the tested parts of the plant. Antibacterial activity displayed the extracts of M. oblongifolia against tested bacteria strains in dose dependent manner. Among tested extracts, roots and stem barks ethanol extracts showed potential antibacterial activity, with zone of inhibitions (19.0 ± 1.15, 17.0 ±1.00) in 100 mg/mL, and (17.3 ± 0.57, 15.0 ± 1.00) in 50 mg/mL, respectively. Conclusion: The finding showed a possibility to shift stem bark instead of roots in the use of traditional medicinal practices to ensure conservation and sustainable use of Maerua oblongifolia. The finding also supports the traditional use of the plant’s root or stem bark for the treatment of diarrhea.

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.

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.
