Background & Aim: Rubiatinctorum is one of the most well-known medicinal plants whose alizarin and other anthraquinones which are outstanding color agents with some trace of pharmaceutical properties are isolated from it. The objective of this study was to optimize alizarin production in intact plant of R.tinctorum by induction with biotic elicitors. ...

Staphylococcal biofilms are problematic and play a critical role in the persistence of chronic infections because of their abilities to tolerate antimicrobial agents. Thus, the inhibitions of biofilm formation and/or toxin production are viewed as alternative means of controlling Staphylococcus aureus infections. Here, the antibiofilm activities of 560 purified phytochemicals were examined. Ali...

The photocatalytic degradation of dyes (alizarin red S, amaranth, congo red, and rhodamine B) present in wastewater was performed with UV lamp. catalysts employed for this investigation were ZnO, TiO2, SnO2. kinetic studies followed first order reaction. ZnO found to be most efficient photo-catalyst degrading these dyes. optimal result alizarin S k = 0.2118 min?1, t1/2 3.27 min, R2 0.7998, amar...

Pt/TiO2 sensitized by the cheap and organic ortho-dihydroxyl-9,10-anthraquinone dyes, such as Alizarin and Alizarin Red, achieved a TON of approximately 10 000 (TOF > 250 h(-1) for the first ten hours) during >80 hours of visible light irradiation (>420 nm) for photocatalytic hydrogen evolution when triethanolamine was used as the sacrificial donor. The stability and activity enhancements can b...

An autocatalytic photoinitiated reaction helps decomposition of the alizarin-based ruthenium(ii) bipyridine complex in presence hydrogen peroxide.

Bu çalışmada, alizarin red S’in silika jel üzerine çözeltiden adsorpsiyonu araştırılmıştır. pH, adsorbent konsantrasyonu ve temas süresi gibi etkenlerin S boyar maddesinin adsorpsiyon davranışı üzerindeki etkisi incelenmiştir. 25 0C sıcaklıkta, 20 mg adsorban mg/L adsorbat çözeltilerle kinetiği, yalancı birinci mertebeden ikinci modelleri olmak üzere iki kinetik model kullanılarak Adsorpsiyonun...

Commercially available dyes of the esculetin and alizarin families are identified as lead structures for constructing ratiometric fluorescent probes for zinc ions.
