Recent data showed that phenylpropanoid compound, methylchavicol is essential component of Iranian cultivars of basil. Studying their occurrence during development of plant may help to elucidate the role of phenylpropanoids in plant cell physiology. We followed the phenylpropanoids concentration and the expression of genes related to their biosynthesis during growth and development of two culti...

Some basil varieties are able to convert the phenylpropenes chavicol and eugenol to methylchavicol and methyleugenol, respectively. Chavicol O-methyltransferase (CVOMT) and eugenol O-methyltransferase (EOMT) cDNAs were isolated from the sweet basil variety EMX-1 using a biochemical genomics approach. These cDNAs encode proteins that are 90% identical to each other and very similar to several is...

Abstract Holy Basil— Ocimum tenuiflorum —is one of the popular new “superfoods” thought to act as an antioxidant and reduce stress anxiety. However, it is often surrogated with other species differing in their chemical profiles that may even pose health risks consumers. Moreover, specific chemotypes Basil itself can be toxicologically relevant, because they sometimes contain carcinogen compound...

Sweet basil (Ocimum basilicum L., Lamiaceae) is a common herb, used for culinary and medicinal purposes. The essential oils of different sweet basil chemotypes contain various proportions of the allyl phenol derivatives estragole (methyl chavicol), eugenol, and methyl eugenol, as well as the monoterpene alcohol linalool. To monitor the developmental regulation of estragole biosynthesis in sweet...

The study of the biosynthesis of secondary metabolites and the genes involved in these processes has been greatly facilitated by novel genomic approaches developed during the last years. Many of the biosynthetic pathways dedicated to secondary metabolism, and the enzymes involved in these pathways, have apparently evolved from the much better studied primary biosynthetic pathways. Therefore by ...

We have previously shown (R.A. Raguso, E. Pichersky [1995] Plant Syst Evol 194: 55-67) that the strong, sweet fragrance of Clarkia breweri (Onagraceae), an annual plant native to California, consists of 8 to 12 volatile compounds, including 4 phenylpropanoids. Although some C. breweri plants emit all 4 phenylpropanoids (eugenol, isoeugenol, methyleugenol, and isomethyleugenol), other C. breweri...

The essential oils of the flowering aerial parts of two Ocimum species viz., Ocimum gratissimum and O. sanctum were analyzed by gas chromatography and gas chromatography/mass spectroscopy. The principal constituent of O. gratissimum and O. sanctum was eugenol (75.1%) and methyl eugenol (92.4%), comprising 99.3 and 98.9% of the total oils, respectively. In vitro antimicrobial activity of the ess...

Anthocyanins and volatile phenylpropenes (isoeugenol and eugenol) in petunia (Petunia hybrida) flowers have the precursor 4-coumaryl coenzyme A (CoA) in common. These phenolics are produced at different stages during flower development. Anthocyanins are synthesized during early stages of flower development and sequestered in vacuoles during the lifespan of the flowers. The production of isoeuge...
