[12] [13] The tropane alkaloids of Atropa belladonna were used as poisons, and early humans made poisonous arrows from the plant. [14] In Ancient Rome , it was used as a poison by Agrippina the Younger , wife of Emperor Claudius on advice of Locusta , a lady specialized in poisons, and Livia , who is rumored to have used it to kill her husband ...
The Australian Phytochemical Survey later also fostered collaborations with Smith, Kline & French, a pharmaceutical company from Philadelphia as well as National Institutes of Health Clinical Center in Bethesda, Maryland which was established in relation to the screening and study of potential anti-tumour agents arising through the survey.

Phytochemistry is the study of phytochemicals, which are chemicals derived from plants.Phytochemists strive to describe the structures of the large number of secondary metabolites found in plants, the functions of these compounds in human and plant biology, and the biosynthesis of these compounds.
Dr. Duke's Phytochemical and Ethnobotanical Databases is an online database developed by James A. Duke at the USDA. The databases report species, phytochemicals, and biological activity, as well as ethnobotanical uses. [1] The current Phytochemical and Ethnobotanical databases facilitate plant, chemical, bioactivity, and ethnobotany searches.
Marquis reagent is used as a simple spot-test to presumptively identify alkaloids as well as other compounds. It is composed of a mixture of formaldehyde and concentrated sulfuric acid, which is dripped onto the substance being tested.
Medical use of alkaloid-containing plants has a long history, and, thus, when the first alkaloids were isolated in the 19th century, they immediately found application in clinical practice. [206] Many alkaloids are still used in medicine, usually in the form of salts widely used including the following: [ 14 ] [ 207 ]
Reaction between alkaloid extract from Capparis spinosa L and Dragendorff’s reagent. Dragendorff's reagent is a color reagent to detect alkaloids in a test sample or as a stain for chromatography plates. Alkaloids, if present in the solution of sample, will react with Dragendorff's reagent and produce an orange or orange-red precipitate. [1]
A number of flavonoid alkaloids have been discovered that possess diverse pharmacological activity that may have application in the treatment of a range of diseases. One example is alvocidib, a potent CDK9 kinase inhibitor that is being developed for the treatment of chronic lymphocytic leukemia (CLL) and acute myeloid leukemia (AML).
