Monoterpenoids from Acanthopanax sessiliflorus fruits.
Three new acyclic monoterpenoids named (2E)-3,7-dimethylocta-2,6-dienoate-6-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside (1), (3Z,6E)-3,7-dimethyl-3,6-octadiene-1,2,8-triol (2) and (6E)-7-methyl-3-methylene-6-octene-1,2,8-triol (3) were isolated from Acanthopanax sessiliflorus fruits, along with three known monoterpenoid compounds. The structures of the new compounds were determined by mean...
متن کاملextraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولImmunostimulating Effects of Extract of Acanthopanax sessiliflorus
As malfunction/absence of immune cells causes a variety of immunosuppressive disorders and chemical synthetic drugs for curing these diseases have many adverse effects, vigorous studies are being conducted. The Acanthopanax family has been used as traditional medicines for gastric ulcer, diabetes, etc. and culinary materials in East-South Asia. In this study, the immunostimulating properties of...
متن کاملAnti-inflammatory lignans from the fruits of Acanthopanax sessiliflorus.
A new lignan, named acanthosessilin A (1), as well as eight known lignan and lignan glycosides 2-9 were isolated from an ethanolic extract of Acanthopanax sessiliflorus fruits. The chemical structures were determined by spectroscopic methods, including HR-EIMS, 1D NMR (1H, 13C, DEPT), 2D NMR (gCOSY, gHSQC, gHMBC, NOESY), and IR spectroscopy. All isolated compounds were tested for the ability to...
متن کاملIMMUNO-MODULATORY PROPERTIES OF PREBIOTICS EXTRACTED FROM vernonia amygdalina
BACKGROUND Vernonia amygdalina, commonly called bitter-leaf, is widely consumed in many parts of Africa, and Nigeria, in particular. The leaf extract has been reported to have antimicrobial, anti-plasmodial, anti-helminthic, as well as prebiotic properties, but its immuno-modulatory effects have not been well-studied, neither have the prebiotics been identified. This study evaluated the immuno-...
