The new isoflavonoid kirkinone A (1) and biflavonoid kirkinone B (2) along with six known compounds (3-8) were isolated from the methanolic extract of the root bark of Ochna kirkii. The compounds were identified by NMR spectroscopic and mass spectrometric analyses. Out of the eight isolated natural ...

Background: Antimicrobial resistance (AMR) remains an important global health issue but the gap between AMR and development of new antimicrobials is increasing. Plant extracts may have good activity per se or may be sources of effective antimicrobial compounds which can act against planktonic...

Terpene synthase (TPS) analysis may contribute to a better understanding of terpenoids biosynthesis and the evolution of phylogenetic taxonomy. Chamaecyparis formosensis Matsumura is an endemic and valuable conifer of Taiwan. Its excellent wood quality, fragrance, and durability make it become the...

Holoptelea integrifolia (Ulmaceae) is a diversely used in Traditional Systems of medicine for healing aliments. The plant is preferred in the treatment and curing diseases like leprosy, inflammation, rickets, leucoderma, scabies, rheumatism, eczema, malaria and many more. The plants exhibits...

The genus Eucalyptus with over 747 species occurs in wide ecological range and is preferred for bioenergy plantations due to their short rotation, rapid growth and superior wood properties. They are planted in 22 million ha area and India is third largest planter of Eucalyptus. In the present...

Phytochemical investigation of the roots of Cola rostrata K. Schum. led to the isolation of a new unsaturated fatty acid, named rostratanic acid (1), together with fourteen known compounds, lignoceric acid, friedelan (7), friedelanone (8), bauerenol (3), lupeol (4), herranone (9), acotatarone A...

Objective: Natural rubber biosynthesis is the typical plant isoprenoid metabolic pathway. The MVA is one of the major metabolic pathways for providing the 5-carbon component units for the subsequent natural rubber or terpenoids biosynthesis. The farnesyl pyrophosphate, forming by the polymerization ...

Microscopic, phytochemical and pharmacological profiles are required for correct identification of a plant material to ensure consistent efficacy and safety. But such data are not available for the leaf of an important medicinal plant, Zizyphus oxyphylla Edgew. (Family: Rhamnaceae). Therefore, the...

The study of the R&D in this paper is to determine the range of essential oils (EOs) in the raw materials of species of the genus Thymus of the natural flora in the Carpathian region and their antimicrobial activity. It was found that the component range of EO in species of the genus Thymus...

This study presents the first report on phenolic composition and bioactivity of ethanolic extracts of three plant species that grow in the western Balkan mountains and are used in traditional folk medicine: Valeriana montana, Salix retusa, and Campanula hercegovina. Phenolics were extracted from...
