The essential oil was obtained from crushed seeds, extracted through Hydrodistillation method. The percentage yield of Carum roxburghianum was found 4.7% respectively. Physical properties i.e., colour, odour, specific gravity, solubility, refractive index, acid value and ester value were recorded according to the standard procedures. Chemical composition of essential oil of Carum roxburghianum ...

Ultrasonic assist with headspace solid phase microextraction (UA-HS-SPME) have been applied, for the first time, for the extraction of volatile organic compounds of Carum carvi L. from Iran. The oils obtained were analyzed by GC–MS. Different experimental parameters such as fiber's coating type, sonication time, extraction time and temperature, and desorption time were investigated. Results sho...

Background & Aim:Satureja Isophylla L.  is a medicinal herb which belongs to the family Lamiacease. Salinity affects the growth, the quality and quantity of essential oils of medicinal plants. Chitosan is also considered as a biological elicitor which plays a role in improving production of secondary metabolites of medicinal herbs. The current project was cond...
