Quantitative and qualitative characterization of volatile oil of Chrysanthemum coronarium in Syria

Abstract

The volatile oil of Chrysanthemum coronarium was studied in four locations in the provinces of Tartous and Latakia. The plants were gathered during tow phonological phases of the life of the plant included the vegetative growth stage- the full of flowering stage. It was then extracted through water extraction method. It was found that the highest percentage of volatile oil was recorded in AL mania location at the full of the flowering stage during the 2019 season, the percentage of the volatile oil was 0.51 (ml/100g)  while the lowest percentage of  volatile oil was recorded in    Safita during  the 2018 season , the percentage of the volatile oil was 0.47 (ml/100g) and the shoot did not contain volatile oil therefore the best stage to collect the plant to either extract the volatile oil or for direct use is the full of flowering stage. The volatile oil were analysed by GC-MS. The main compounds were:

Camphor 21.36- 33.2%,     Santolina triene15.9-39.11%,

 Terpinen-4-ol 2.92 – 6.71%, Dehydroxy-cis-linalool oxide 12.09-16.36%

cis-Chrysanthenyl acetate 2.2- 6.89%, Camphene 2.82- 6.18%.
