Novel Ecdysteroids from Serratula wolffii
Two new and one known ecdysteroids were identified in the methanolic extract of the roots of Serratula wolffii. The new compounds isolated were ponasterone A-22-apioside (1) and 3-epi-shidasterone (3), together with the known 3-epi-22-deoxy-20-hydroxyecdysone (2). The structures of compounds 1-3 were determined by extensive spectroscopic techniques, including one- and two-dimensional NMR methods.
متن کاملSterols and Flavonoids of Lomatopodium staurophyllum
Background: The genus Lomatopodium Fisch. & C.A.Mey., belongs to Apiaceae family and contains one herbaceous species growing wildly in Iran. There are only a few papers about the chemical constituents of these plants. Here, we focused on the isolation and identification of the main flavonoid glycosides and sterols from the aerial parts of L. staurophyllum, which has not been previously reported...
متن کاملEcdysteroids from the Antarctic tunicate Synoicum adareanum.
Five new ecdysteroids, hyousterones A-D (2-5) and abeohyousterone (6), have been isolated from the Antarctic tunicate Synoicum adareanum along with the known ecdysteroid diaulusterol B (1). Hyousterones B (3) and D (5) are unusual ecdysteroids in bearing the 14beta-hydroxyl group, and abeohyousterone incorporates the 13(14-->8) abeo steroid skeleton, reflecting a rearrangement of the steroid C/...
متن کاملThe minor ecdysteroids from Ajuga turkestanica.
INTRODUCTION Ajuga turkestanica is a plant used in traditional medicine for its high ecdysteroid content, including the presence of the particularly active turkesterone, which possess efficient anabolic activity. OBJECTIVES To isolate and identify minor ecdysteroids present in a semi-purified plant fraction containing ca. 70% turkesterone. MATERIAL AND METHODS Multi-step preparative HPLC (c...
متن کاملEcdysteroids: A novel class of anabolic agents?
Increasing numbers of dietary supplements with ecdysteroids are marketed as "natural anabolic agents". Results of recent studies suggested that their anabolic effect is mediated by estrogen receptor (ER) binding. Within this study the anabolic potency of ecdysterone was compared to well characterized anabolic substances. Effects on the fiber sizes of the soleus muscle in rats as well the diamet...
