Phytosteroids, also known as plant steroids, are naturally occurring steroids that are found in plants. [1] Examples include digoxin , digitoxin , diosgenin , and guggulsterone , as well as phytosterols like β-sitosterol and other phytoestrogens like isoflavones .
Plants, but not animals, synthesize phytoecdysteroids from mevalonic acid in the mevalonate pathway of the plant cell using acetyl-CoA as a precursor. Some ecdysteroids, including ecdysone and 20-hydroxyecdysone (20E), are produced by both plants and arthopods. [ 1 ]
Alkaloids are found in the roots and rhizomes of these plants. [35] They include veratridine, cyclopamine, and jervine. [20] Because of their actions on the cardiovascular, neuromuscular, and respiratory systems, Veratrum alkaloids have been used for the treatment of various conditions like myasthenia gravis, hypotension, and eclampsia.

Distribution in pharmacology is a branch of pharmacokinetics which describes the reversible transfer of a drug from one location to another within the body.. Once a drug enters into systemic circulation by absorption or direct administration, it must be distributed into interstitial and intracellular fluids.
It has been found to increase hypertrophy in rats at a similar level to some anabolic androgenic steroids and SARMs. [11] This is proposed to be through increase of Calcium leading to activation of Akt and protein synthesis in skeletal muscles. [12] A newer study points to estrogen receptor beta. [13] 20-hydroxyecdysone is a human drug ...
Phytosterols are phytosteroids, similar to cholesterol, that serve as structural components of biological membranes of plants. [1] They encompass plant sterols and stanols . [ 1 ] More than 250 sterols and related compounds have been identified. [ 2 ]

Brassinolide, the first brassinosteroid isolated and shown to have biological activity. Brassinosteroids (BRs or less commonly BS) [1] are a class of polyhydroxysteroids that have been recognized as a sixth class of plant hormones and may have utility as anticancer drugs for treating endocrine-responsive cancers by inducing apoptosis of cancer cells and inhibiting cancerous growth.
