چکیده
این مطالعه به منظور استخراج روغن اسانسی گیاه کبر و آنالیز اجزای تشکیل دهنده آن انجام شد. در این مطالعه برای اولین بار ترکیب های شیمیایی اسانس گل و جوانه گل کبر در دو مرحله برداشت شامل قبل از طلوع آفتاب و بعد از طلوع آفتاب با دستگاه GC/MS آنالیز گردید. نتایج آنالیز اسانس نشان داد 30، 20، 27 و 7 ترکیب بترتیب در اسانس جوانه گل بعد از طلوع آفتاب، جوانه گل قبل از طلوع آفتاب، گل باز شده قبل از طلوع آفتاب و گل باز شده بعد از طلوع آفتاب شناسایی شد. ترکیبات ایزوتیوسیاناتی و ترپنی بیشترین درصد ترکیبات را در همه ی نمونه ها شامل بود. ترکیب اصلی تشکیل دهنده نمونه های اسانس Isobutyl isothiosyanate بود. تعداد 17 ترکیب در نمونه های گل و جوانه گل بعد از طلوع خورشید با هم مشترک بودند. همچنین نتایج نشان داد که ترکیب کارواکرول در نمونه های برداشت شده در اسانس گل و جوانه گل بعد از طلوع آفتاب ترکیب غالب بود. با توجه به نتایج این تحقیق بسته به نوع ترکیب مورد نظر روش برداشت از اندام های گیاه کبر می تواند متفاوت باشد.

چکیده English

The present study was conducted to investigate the chemical composition of the Caper flower and flower buds essential oil in two harvesting stages of before and after sunrise. Harvesting of perennial plants in July 2017 was carried out on wilding specimens at Imamzadeh Jafar Research Farm in Gachsaran City. Essence of the samples of the Clevenger apparatus were extracted and the essential oils were identified by GC / MS. In the study of the chemical composition of Capparis spinosa L. flower and flower buds essential oil in two harvesting periods, it was determined that generally, the essential oil of flowers after sunrise, flower buds before sunrise, flowers opened before sunrise, and flowers opened after sunrise contain 30, 20, 27 and 7 chemical compositions respectively.

Isobutyl isothiosyanate was found in all essential oil samples. There were 17 compositions in flower and flower buds samples after sunrise. The results showed that carvacrol in the harvested samples in flower and flower buds essential oil after sunrise was the dominant composition. In general, the isothiocyanate and terpene compositions are the dominant components in all specimens. The results showed that in samples after sunrise, the amount of essential oil composition is higher than that before sunrise, which is due to the presence of light and heat that causes changes in essential oil composition
