In this study, the essential oil chemical compounds of rosemary (Rosmarinus officinalis L.) and its antioxidant activity on oxidation stability refined sunflower (RSO) were investigated by Rancimat method. The plant material was obtained from Afyonkarahisar Medicinal Aromatic Plants Center/Turkey. Based GC/FID-MS analysis result, 1,8-Cineole (15.18%), Camphor (11.39%), Borneol Germacrene D (11....

A very simple, rapid and sensitive dispersive liquid-liquid microextraction (DLLME) followed by gas chromatography and flame ionization detection (GC-FID) was developed for the determination of phenol and carvacrol in honey samples. A mixture of 100 µl dichloromethane (extraction solvent) and 0.5 ml acetonitrile (disperser solvent) was rapidly injected into sample solution. Thereby a cloudy sol...

interspecific or intergenus hybridization in sugarbeet (b. vulgaris l.) is usually failed due to non fertilization, embryo death or absence of connection between embryo and endosperm. consequently invitro embryo rescue technique is of value to save hybrid embryos before annihilation. sugar beet inter-specific crosses with wild species is impossible in classical breeding because of no chromosoma...

BACKGROUND Chlorophytum borivilianum is an industrially valued medicinal crop. Propagation through seeds is not feasible because of low germination percentage and long dormancy period. Therefore, callus culture and plant regeneration can be an alternative to improve this crop production. Also, callus can serve as an alternative source of bioactive compounds. OBJECTIVE To evaluate the effect o...

Background: Cryopreservation of ovary for preserving germ cell line is going to be an important issue. However, the physical and chemical stresses during cryopreservation are the most important factors that may influence the post freezing tissue viability and quality. Vitrification is a new approach to bypass the impacts of both stresses for gametes and embryos and it is also suggested for ovar...

Recently it was reported that l~«,25-dihydro\y vitamin O, [1,25iOH)zl),l inhibited cell growth in a cell Une derived from a metastasis from renal cell carcinoma. We have examined samples from 23 primary renal cell carcinomas for I,2S-(<)H)2D, receptor content, and compared it with the concentrations in autologous normal kidney tissue. Nineteen of 23 (83%) renal cell carcinomas had detectable (...

Background: Ferulago angulata is an important medicinal plant and endemic to Iran which is an endangered Plant. Objective: The aim of this study was to achieve an efficient method for propagation of this plant and evaluation of essential oil content and composition in habitat. Metthods: Essential oils were extracted by hydrodistillation using Clevenger-type apparatus and its composition was ...
