Separation Methods for Phytoecdysteroids
نویسنده
چکیده
Introduction The effectiveness of natural health preparations is based on the amount/ratio of their active ingredients. This can differ in plants depending on the species variant, the part of the plant used, the season or the micro-climate. Moreover, the method of harvest, the drying and extraction techniques used, and any further processing also influence the final composition of medicinal health preparations. Several plants yield a series of active compounds with similar chemical structures, and some compounds may be subjected to chemical degradation or structural transformation during their processing. Analytical methods support the reliable control of medicinal health preparations, and the control of choice has always been chromatography.

Using pure phytoecdysteroids isolated from Ajuga iva (L.) Schreber (Lamiales: Lamiaceae) and Silene nutans L. (Caryophyllales: Caryophyllaceae), plants known for their high ecdysteroid content, a study was carried out on the effects of ingestion of four different phytoecdysteroids (20-hydroxyecdysone, polypodine B, ponasterone A and makisterone A) on the growth and development of the Indian mea...

Four phytoecdysteroids: (20-hydroxyecdysone-20, 22-monacetonide (1), 20-hydroxyecdysone (2), stigmasterol (3), gamma-sitosterol (4), were investigated for toxic effect against 3 rd /4 th instar larvae of Anopheles gambiae under laboratory conditions as individual compounds and in blends. The test larvae were treated with solutions containing the phytoecdysteroids of concentrations 1, 5 and 10pp...
متن کاملPhytoecdysteroids: Isolation and Biological Applications
Phytoecdysteroids are analogues of arthropod steroid hormones found in plants, where they deter predation by non-adapted predators. Their discovery in several plant species displayed a wide array of rather beneficial agricultural impact. An overview is given on both well-known and recently discovered phytoecdyteroids including a sophisticated isolation scheme and notable physiological and pharm...

BACKGROUND Ecdysteroids are steroid hormones that control moulting and govern several changes during metamorphoses in arthropods. The discovery of the same molecules (phytoecdysteroids) in several plant species displayed a wide array of rather beneficial agricultural impact. Many representatives of the genus Ajuga plants contain phytoecdysteroids with a 5β-7-ene-6-one system exhibiting physiolo...
