All active ingredients [Baicalin, Liquiritin, Indigotin, Indirubin,
Sitosterol, Chlorogenic acid, Matrine, Daidzein, Betaine, Oleanolic acid, Vitamin C, Vitamin E, Folate] were suspended in DMSO and diluted to final concentration 25 umol L-1 in DMEM without FBS and antibiotics as the ligand supplemented media.
The corresponding secondary ions can be attributed to campesterol (383),
sitosterol (397) and different steryl esters (411,423, 439)9,10,11 (see fig.
8), especially
sitosterol and stigmasterol, showing the uncertain source of origin of both compounds, which may be of terrestrial origin in some areas and marine origin in others.
In phytophagous insects the requirement can be fulfilled also with plant sterols e.g.,
sitosterol (3), campesterol (4) and stigmasterol (5), since these C-24 alkylated sterols are metabolically converted to cholesterol.
catappa seed oil were mainly Gamma ([gamma])
sitosterol and beta ([beta])
sitosterol (Table 4).
This analysis should include not only cholesterol and its precursors, but also plant sterols such as
sitosterol and campesterol, and cholesterol oxidation products.
In addition, the company will highlight its pumpkin seed oil, which is naturally rich in beta
sitosterol, and demonstrate its latest innovation in food applications: a powder that's rich in omega-3 DHA, has no taste, no odour and ideal for bakery products.
The second compound was identified as ss -
sitosterol on the basis of following charaters: M.
Fish develop infertility when exposed to high levels of wood pulp, which is rich in
sitosterol, in the water.
The limit of detection (LOD, S/N ratio > 3) and the limit of quantification (LOQ, S/N ratio > 10) were determined on the basis of
sitosterol. The LOD of the GC signal of
sitosterol was 5 [micro]g/mL and LOQ was fixed at 62 [micro]g/mL.
Major sterol components found in human feces include coprostanol, 24-ethylcoprostanol, cholesterol, 24-ethylcholesterol, 5[beta]-stigmasterol, 5[beta]-epistigmasterol, campestanol,
sitosterol, and sitostanol.
