Abstract

The extraction
of Lavandula Officinalis (lavender) and Hypericum Perforatum (centaury)
plants grown in Mersin region were extracted by supercritical carbondioxide
extraction system (P=100 bar, T=40^o C). The chemical composition of
the lavender and centaury extracts were analysed by Gas Chromatography–Mass
Spectrograph (GC-MS). For antioxidant activity experiments, 1,1-diphenyl-2-pycrylhidrazine
(DPPH) radical was used in radical effect tests. For antimicrobial activity studies,
Bacillussubtilis, Klebsiellapneumoniae, Escherichiacoli,
Staphylococcusaureus, Pseudomonasaeruginosa and Streptococcuspneumoniae
with Nutrient Agar Broth (NA) and Eosin Methylene-blue lactose sucrose agar
(EMB) broth were used. For determining antimicrobial effect of plant extracts,
diffusion method was used. Antibacterial and antioxidant properties of the obtained
extracts were examined and have been determined that the resulting extracts
have significant antioxidant and antimicrobial effect. The extracts were also
used in cosmetic cream formulas as protectives. Effective results have also
been determined in antibacterial activity studies of creams after 6 months.
