Steroid isolation , depending on context, is the isolation of chemical matter required for chemical structure elucidation, derivitzation or degradation chemistry, biological testing, and other research needs (generally milligrams to grams, but often more [38] or the isolation of "analytical quantities" of the substance of interest (where the focus is on identifying and quantifying the substance (for example, in biological tissue or fluid). The amount isolated depends on the analytical method, but is generally less than one microgram. [39] [ page needed ] The methods of isolation to achieve the two scales of product are distinct, but include extraction , precipitation, adsorption , chromatography , and crystallization . In both cases, the isolated substance is purified to chemical homogeneity; combined separation and analytical methods, such as LC-MS , are chosen to be "orthogonal"—achieving their separations based on distinct modes of interaction between substance and isolating matrix—to detect a single species in the pure sample. Structure determination refers to the methods to determine the chemical structure of an isolated pure steroid, using an evolving array of chemical and physical methods which have included NMR and small-molecule crystallography . [2] : 10–19 Methods of analysis overlap both of the above areas, emphasizing analytical methods to determining if a steroid is present in a mixture and determining its quantity. [39]

In global terms, animal feeds and forages contain a wide range of contaminants and toxins arising from anthropogenic and natural sources. In this article, the distribution of heavy metals, radionuclides, mycotoxins, plant toxins, antibiotics and microbial pathogens in cereals, complete feeds and forages is reviewed. The impacts on farm livestock productivity and on the safety of resulting edible products are also considered. Evidence is provided to demonstrate that feeds contain a variety of substances as co-contaminants and that there are regional differences in the nature of the compounds involved. It is concluded that the options for remedial action are limited. Furthermore, although many developing countries lack appropriate legislation, change in this respect is inevitable as regulatory controls for feeds imported into Europe and America are strengthened.

Smilax Sieboldii is a climbing shrub which mainly grows in East Asia, and South and North America [1]. Its young leaves are used for food and the subterranean parts have been used in Traditional Chinese Medicine (TCM) for arthritis, tumors and lumbago [2, 3]. This plant has aroused researches tremendous attention because of a natural steroidal sapogenin-laxogenin [4]. Laxogenin is a spirostanic analogue of brassinosteroid, shown to possess an anabolic/androgenic activity similar to one of the most efficient anabolic substances, anavar, yet without the side effects of liver toxicity or likelihood of testing positive for steroid [5].
5α-HydroxyLaxogenin, a homolog of laxogenin, is also a natural steroidsin green plant [5]. In the earliest time, both two plant-based steroids are sold in the market, while with the time being, consumers prefer to choose 5α-HydroxyLaxogenin. They strongly reflected that 5α-HydroxyLaxogenin had a better anabolic effect on their body than laxogenin, although the mechanism needs further studied.

Isolation of a new saponin and cytotoxic effect of saponins from the root of Platycodon grandiflorum on human tumor cell lines.
Planta Med. 2005.
A novel triterpenoid saponin, deapioplatycoside E was isolated from the root extract of Platycodon grandiflorum, together with the seven known saponins, i. e., platycoside E, deapioplatycodin D3, platycodin D3 (4), polygalacin D2 (5), platycodin D2 (6), deapioplatycodin D (7) and platycodin D (8). The crude saponin fraction (ED50: ca. 10 - 15 microg/mL) and compounds 6 - 8 exhibited significant inhibition on the proliferation of five kinds of cultured human tumor cell lines, i. e., A549 (non-small cell lung), SK-OV-3 (ovary), SK-MEL-2 (melanoma), XF498 (central nerve system) and HCT-15 (colon), in vitro.
