Investigation of metal ion accumulation in Euglena gracilis by fluorescence methods

Determination of element contents in herbal drugs: Chemometric approach

“…Depending on their concentration some elements can play different roles in plant (Bennett, Chiriboga, Coleman, & Waller, 2000). Zinc, Mn and Fe are important co-enzymes; Cu is bound to amino acid (Shi, Chen, Huang, & He, 2004) while Mn forming coordination compounds (Shen et al, 2002). Most of the elements studied were important in antioxidant processes; deficiency of any of these essential elements may impair the function of overall oxidant system (Lemberkovics et al, 2002).…”

SRXRF microprobe as a technique for studying elements distribution in Elsholtzia splendens

“…SRXRF microprobe has sufficient spatial resolution and analytical sensitivity to provide information on metal distribution within plants at the cellular level. As a part of an upgrade program of the BSRF, a new permanent-magnetic wiggler was installed at the end of 1996 (Shen et al, 2002). The beam produced a scanning spot of 10 £ 10 mm 2 using only slits while minimum detection limits were better than 0.01 pg.…”

Lanthanides and Algae

“…Even in higher plants, which are much more researched, cell processes responsible for lanthanide intake have only recently been described [38]. Several studies have shown that lanthanides concentrate in chloroplasts [93,94,[106][107][108]. It was demonstrated that selective deposition of individual lanthanides in chloroplasts or the cytoplasm occurs in the green alga Desmodesmus quadricauda [109].…”
