4. Conclusion
The oil obtained from dry capsules has been found to be rich in
unsaturated fatty acids (oleic and linoleic). Considering the usage
areas of these two fatty acids, the oil obtained from Hypericum capsules
has the potential to be evaluated in different areas. Significant
effects of different development periods on herbage essential oil rate
and composition were determined. The chemical composition of essential
oil in medicinal and aromatic plants is an important factor that
determines quality. The amount and composition of essential oil
contained in plants is an indicator of the economic value of that
product. Considering the change of bioactive substances in plants, it
should be well known in which development period the plant will be
collected/harvested. According to result of the literature searches,
germacrene-D, bicyclogermacrene,δ -cadinene, spathulenol, α -guaiene, and valencene in
herbage essential oil and limonene, cis -ocimene,β -myrcene, and α, β -pinene in dry capsule were determined
that they exhibited important biological activities. A lot of
information obtained from this study, in which some plant and chemical
properties of H. heterophyllum , which is an endemic plant, is
examined, is the first. Therefore, the findings obtained will form an
important basis for future studies.
