“…Additionally, there are some variations of the hydroxyl and conjugating group (such as position, number, and orientation) in the steroid ring structure; sometimes, an oxo group occurs in C-2, C-6, C-12, C-17, C-20, or C-22. These crucial modifications synthesize diverse forms of metabolites in different plants [ 7 ].…”

“…Zoo- and mycoecdysteroids are present in extremely low concentrations in organisms and cannot be isolated for practical purposes. PEs are found in more than 100 terrestrial fern, gymnosperm, and angiosperm plant families [ 4 , 7 , 18 , 23 , 24 ]. The occurrence of three ECs, named ponasterones A, B, and C, in the leaves of Podocarpus nakaii was reported for the first time in plants [ 25 , 26 ].…”

“…The taxons that are used in traditional medicines such as Leuzea carthamoides , Ajuga turkestanica , and several Pfaffia species have abundant ECs in their roots. Cyanotis vaga and Cyanotis arachnoidea belong to monocot species, and several species of ferns that belong to Polypodium are rich sources of ECs [ 7 , 8 , 30 , 31 , 32 , 33 , 34 , 35 ].…”

“…About 200 PEs are found in different plant genera, such as Polypodium , Ajuga , Silene , and Podocarpus [ 7 , 8 ]. A total of 207 new PEs have been identified from 17 plant families: Amaranthaceae, Asteraceae, Blechnaceae, Caryophyllaceae, Commelinaceae, Dioscoreaceae, Gleicheniaceae, Lamiaceae, Liliaceae, Limnanthaceae, Lygodiaceae, Malvaceae, Menispermaceae, Polypodiaceae, Polyporaceae, Rhodomelaceace, and Taxaceae ( Table 1 ).…”

“…The naturally occurring ECs found in plants are differentiated from the ECs found in animals. However, 20-hydroxyecdysone (20-HE) is the most common and widely used [ 4 , 5 , 6 , 7 ]. Many ECs are present in plants and animals, such as 20-HE, ecdysone, ajugasterone C, polypodine B, and cyasterone ( Figure 1 ).…”

Phytoecdysteroids (PEs) are naturally occurring polyhydroxylated compounds with a structure similar to that of insect molting hormone and the plant hormone brassinosteroids. PEs have a four-ringed skeleton composed of 27, 28, 29, or 30 carbon atoms (derived from plant sterols). The carbon skeleton of ecdysteroid is known as cyclopentanoperhydrophenanthrene and has a β-sidechain on C-17. Plants produce PEs via the mevalonate pathway with the help of the precursor acetyl-CoA. PEs are found in algae, fungi, ferns, gymnosperms, and angiosperms; more than 500 different PEs are found in over 100 terrestrial plants. 20-hydroxyecdysone is the most common PE. PEs exhibit versatile biological roles in plants, invertebrates, and mammals. These compounds contribute to mitigating biotic and abiotic stresses. In plants, PEs play a potent role in enhancing tolerance against insects and nematodes via their allelochemical activity, which increases plant biological and metabolic responses. PEs promote enzymatic and non-enzymatic antioxidant defense systems, which decrease reactive oxygen species in the form of superoxide radicals and hydroxyl radicals and reduce malondialdehyde content. PEs also induce protein biosynthesis and modulate carbohydrate and lipid synthesis. In humans, PEs display biological, pharmacological, and medicinal properties, such as anti-diabetic, antioxidant, anti-microbial, hepatoprotective, hypoglycemic, anti-cancer, anti-inflammatory, antidepressant, and tissue differentiation activity.

This study reports the isolation of steroid glycosides and cycloartane glycosides from the aerial parts of Silene tomentella. Two cycloartans group of triterpenoids astrasieversianin II (1) and cycloastragenol (4), including two compounds belonging to steroid glycosides lokundjoside (2) and lineolon (3) are known, were isolated from the aerial part of S. tomentella by chromatographic techniques (CC, TLC, HPTLC). Their structures were established based on extensive spectroscopic analyses and chemical methods, including NMR (1D and 2D) and HR-ESI-MS data. All of these compounds were obtained for the first time for this plant. In addition, the antimicrobial activities of triterpene and steroid glycosides were evaluated against Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Bacillus subtilis as well as fungi Candida albicans. There was no evidence of antimicrobial action in the isolated triterpene glycosides and steroid glycosides against used microorganisms
