Sinecatechins, the first botanical drug approved by the US FDA, is an extract from the leaves of Camellia sinensis.. A botanical drug is defined in the United States Federal Food, Drug, and Cosmetic Act as a botanical product that is marketed as diagnosing, mitigating, treating, or curing a disease; a botanical product in turn, is a finished, labeled product that contains ingredients from plants.
The following is a table of drugs organized by their year of discovery. Naturally occurring chemicals in plants, including alkaloids, have been used since pre-history.In the modern era, plant-based drugs have been isolated, purified and synthesised anew.
Plants need to defend themselves from attack by micro-organisms, in particular fungi, and they do this by producing anti-fungal chemicals that are toxic to fungi. Because fungal and human cells are similar at a biochemical level it is often the case that chemical compounds intended for plant defence have an inhibitory effect on human cells ...
Hyoscyamine can be extracted from plants of the family Solanaceae, notably Datura stramonium. As hyoscyamine is a direct precursor in the plant biosynthesis of hyoscine, it is produced via the same metabolic pathway. [18] The biosynthesis of hyoscine begins with the decarboxylation of L-ornithine to putrescine by ornithine decarboxylase (EC 4.1 ...
The firms that are overdue for safety and quality inspections represent about 42% of the 4,700 plants that are currently registered to produce drugs for the U.S. and previously underwent FDA ...
The pharmaceutical industry has remained interested in mining traditional uses of medicinal plants in its drug discovery efforts. [45] Of the 1073 small-molecule drugs approved in the period 1981 to 2010, over half were either directly derived from or inspired by natural substances.
Galantamine is a type of acetylcholinesterase inhibitor.It is an alkaloid extracted from the bulbs and flowers of Galanthus nivalis (common snowdrop), Galanthus caucasicus (Caucasian snowdrop), Galanthus woronowii (Voronov's snowdrop), and other members of the family Amaryllidaceae, such as Narcissus (), Leucojum aestivum (snowflake), and Lycoris including Lycoris radiata (red spider lily).

Ibogaine is a psychoactive indole alkaloid obtained either by extraction from plants in the family Apocynaceae such as Tabernanthe iboga, Voacanga africana, and Tabernaemontana undulata or by semi-synthesis from the precursor compound voacangine, another plant alkaloid. [1] [2] The total synthesis of ibogaine was described in 1956. [5]
