“…Cleavage of the methylenedioxy ring of nitrosafrol took place during the conversion into the catechol 4 (57.4% yield) using the AlCl 3 /CH 2 Cl 2 /H 2 O method [12][13][14][15] . In the 1 H NMR spectrum, the absence of the methylenedioxy singlet between 5.90-6.05 ppm confirmed the presence of catechol coupled with a broad signal at d=8.99 (brs, 2H).…”

Safrole from sassafras oil (Ocotea pretiosa Mez., Lauraceae), is an abundant natural product showing interesting functionality and chemical structure. Starting from safrole, nine derivatives were prepared and assessed for antiproliferative effect using different human cell lines. The in vitro growth inhibition assay was based on the sulphorhodamine dye to quantify cell viability. Some safrole derivatives, (2E)-3-(3',4'-methylenedioxi)phenyl acrylaldehyde (3) and 4-allyl-5-nitrobenzene-1,2-diol (4) presented better antiproliferative effect than the parent compound on two breast cancer cell lines (MCF-7 and MDA-MB-231) and one human colorectal cancer cell line (DLD-1) with IC 50 values of 55.0 + 7.11 µM, 37.5 + 2.65 µM and 44.0 + 6.92 µM, respectively, without toxicity towards dermal human fibroblast (DHF cells).

“…DC., popularly known as long pepper, is rich in safrole, a phenylpropanoid that is currently being used as a raw material for the manufacture of heliotropin, an important component of some perfumes, and piperonyl butoxide, a pesticide synergist for natural insecticides (Fazolin et al, 2007). Studies by Barreiro and Fraga (1999) and Costa (2000) on the chemical reactivity of safrole (2) and the acquisition of synthetic analogues have indicated great synthetic variability and excellent opportunities for their derivation.…”

“…Além de ser utilizado na aromatização de alimentos e perfumaria, pode ser usada como uma importante fonte de eugenol, substância utilizada para produzir a vanilina. Além da vanilina, o eugenol pode ser usado como precursor para a preparação de naftoquinonas, antraquinonas, dentre outras (Costa, 2000). O óleo essencial da P. dioica, também exibe várias atividades biológicas.…”

RESUMO: Utilizando a técnica de hidrodestilação, usando um adaptador Clevenger, foram extraídos óleos essenciais das espécies Pimenta dioica (folhas e frutos) e Syzygium aromaticum (botões florais, talos e folhas). A composição química dos óleos foi determinada através da analise CG-EM. Os teores de óleos essenciais variaram de 0,97 a 1,41% e 2,30 a 15,40% nas espécies Pimenta dioica e Syzygium aromaticum, respectivamente. O componente majoritário presente nessas espécies foi o eugenol, variando de 72,87 a 90,41%. Syzygium aromaticum forneceu maior teor de óleo essencial rico em eugenol. Em quantidades menores foram também encontrados chavicol e β-cariofileno.Unitermos: Syzygium aromaticum, Pimenta dioica, Myrtaceae, eugenol, Brasil, óleo essencial.ABSTRACT: "Volatile chemical constituents of rich spices in eugenol". Essential oils were extracted from the leaves and fruits of Pimenta dioica and leaves, stalks and floral buttons from Syziguim aromaticum by hydrodistillation using a Clevenger apparatus. The essential oil compositions were determined by CG-MS analyses. The yield varied from 0.97 to 1.41% and from 2.30 to 15.40% in the P. dioica and S. aromaticum, respectively. In both species the major component was the eugenol, varied from 72.87 to 90.41%, being richer the essential oil extracted from S. aromaticum. Chavicol and β-caryophyllene were identified in low percentage.
