Acute toxicity and pharmacological actions of rosolic acid.
Acute toxicity and pharmacological actions of rosolic acid were studied. Results: ( 1) LD 50 s of rosolic acid on mice were 82 ( 78-87) mg/kg s.c. and 49 (41-58) mg/kg i.p. The animals survived after the oral administration. (2) Significant irritation on the mucosa was not observed. (3) Rosolic acid produced a rise in the blood pressure and a transient depression of respiration in the rabbit. (...
متن کاملDetermination of Acidity Constants of p-Rosolic acid and Bromoxylenol Blue by Solution Scanometric Method
Recently solution scanometry, as a new, simple, fast, portable, and economic method was introduced for determination of acidity constants of indicator and dyes. In this study, a method was applied for the determination of the acidity constant of p-Rosolic acid (RA) and Bromoxylenol blue (BXB) indicators. The method is based on scanning of Plexiglas® sheet containing colored solutions with a fla...
متن کاملDifferential activation of heme oxygenase-1 by chalcones and rosolic acid in endothelial cells.
The induction of heme oxygenase-1 (HO-1) is widely recognized as an effective cellular strategy to counteract a variety of stressful events. We have shown that curcumin and caffeic acid phenethyl ester, two naturally occurring phytochemicals that possess antioxidant, anti-inflammatory, and anticarcinogenic activities, induce HO-1 in many cell types. This suggests that stimulation of HO-1 could ...
متن کاملstudy of dna interaction with ethylenediaminetetraacetic acid and sesamol food additives
برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...
