    Area of Science:

    • Phytochemistry
    • Natural Products Chemistry
    • Ethnobotany

    Background:

    • Alkaloids are a diverse group of naturally occurring organic compounds that contain at least one nitrogen atom.
    • Many alkaloids exhibit significant pharmacological activities, making them valuable in medicine.
    • Systematic screening of plant species is crucial for discovering new alkaloid sources.

    Purpose of the Study:

    • To screen a large collection of plant extracts for the presence of alkaloids.
    • To identify novel plant species containing alkaloids.
    • To contribute to the growing database of alkaloid-bearing flora.

    Main Methods:

    • Screening of 1,005 plant extracts using established chemical tests for alkaloids.
    • Documentation of positive results and identification of plant species.

    Related Experiment Videos

  • Comparison with previous findings in the series.
  • Main Results:

    • A total of 267 out of 1,005 plant extracts tested positive for alkaloids, representing a 34.01% yield.
    • 137 of the alkaloid-positive species are reported as new to the scientific literature.
    • Cumulatively, the series has screened 4,990 extracts from 4,103 species, with 1,069 yielding positive results.

    Conclusions:

    • The screening of plant extracts remains a productive strategy for alkaloid discovery.
    • A significant proportion of newly screened species contain alkaloids, highlighting unexplored phytochemical potential.
    • Continued research in this area is essential for uncovering novel bioactive compounds from the plant kingdom.
