مقايسه كميت و كيفيت اسانس حاصل از گلبرگ و ساير اجزاي گل (نهنج، كاسبرگ، مادگي و پرچم) در دو ژنوتيپ از گل محمدي Rosa damascena

Comparison of quantity and quality of the essential oils of different parts of rose flower (petals, sepals and other parts) in two genotypes of Rosa damascena

Rosa damascena Mill, commonly known as rose plant belonging to the family rosaceae, is an important aromatic plant. This plant has been cultivated in Iran from many years ago. Due to the literature review, distillation of rose and obtaining rose water was done in Iran for the first time. In this investigation, the oil yield and composition of petals and the other parts of flowers were compared. The results showed the oil of rose petals has the best quantity and quality (high percentage of geraniol and citronellol) and the lowest percentage of waxes. While, trace amount of geraniol and citronellol were found in the oils of other flower parts of Rose, but the amount of waxes was high. Some components like geranyl acetone, methyl eugenol, hexadecanol and heneicosane thet were not found in the petal oil or found in small content, were found in the oil of other parts of rose flower at high amount. So, for oil preparation, using the petals without other parts of flower is recommended.
