Appraisal of biological activities of crude extracts with subfractions and phytochemical content of endemic Nepeta nuda L. subsp. lydiae from Turkey.
No full textAntioxidant activity of crude water extract (CWE) of this plant and its five sub-fractions (namely,
hexane fraction (HF), chloroform fraction (CFF), ethyl acetate fraction (EAF), n-butyl alcohol fraction (BAF)
and rest of the fractions (RF) were measured using in vitro two antioxidant assays: DPPH and ferrous ion
chelating. Also, quantitative content of total flavonoids and phenols were carried out by colorimetric methods,
using aluminum chloride method and Folin Ciocalteu reagent respectively. CWE and five sub-fractions possessed
different antioxidant activities in antioxidant assays. EAF showed the most potent activity on DPPH
radicals and ferrous ion chelating activities with IC50 values of 10.45 and 16.76 μg /ml respectively. EAF had the
highest total phenolics (145.06 μg GAE/mg dried extract or fraction) and total flavonoids (50.16 μg QEE/mg
dried extract or fraction) contents. The essential oil of the aerial parts of this plant was analyzed by headspace gas
chromatography mass spectroscopy (HS-GC/MS) for the first time and fifty nine components were identified
representing 95.91% essential oil. 1,8-cineole (28.79%), nepetalactone (9.93%), sabinene (7.88%) and α-pinene
(5.71%) were identified as the major components. The essential oil analyzes results have given some clues on the
commercial usable, renewable resources and potentials usable of the Nepeta taxa

match the local environmental conditions and above
all, the plantation of the local plants in the large
ecological scales provide significant contributions
to the life of the natural living communities. The use
of local plants in landscaping and gardens provides
advantages in many aspects such as diversity in landscape,
conservation of gene resources, reduction of
storage costs, and prevention of erosion as well. The
most important advantage of using a native plant is
that decreasing the damage caused by the naturally
collection of the plant species used in the landscape
