naphthoquinones and indoleacetic-acid

Naphthoquinones, plants secondary metabolites are known for their antibacterial, antifungal, anti-inflammatory, anti-cancer and anti-parasitic properties. The biological activity of naphthoquinones is connected with their ability to generate reactive oxygen species and to modify biological molecules at their nucleophilic sites. In our research, the effect of naphthazarin (DHNQ) combined with 2-hydroxy-1,4-naphthoquinone (NQ-2-OH) or 1,4-naphthoquinone (1,4-NQ) on the elongation growth, pH changes of the incubation medium, oxidative stress and redox activity of maize coleoptile cells were investigated. This paper describes experiments performed with maize (

To explore cultural conditions of shikonin production by cell cultures of Lithospermum erythrorhizon.. Orthogonal design was applied in determination of shikonin within the medium. Flask test was applied in the study of shikonin production by the amount of ventilation.. The best medium consisted of 100 mg/L L-phenylalanine, 2 mg/L IAA and 800 mg/L Ca(NO3)2 4H2O. The best amount of ventilation was get by shaken at 150 r/min.. This test provided data for producing shikonin by cell cultures of Lithospermum erythrorhizon.
