“…[1,2] Two characteristic groups of compounds from this species, curcuminoids and sesquiterpenes, were showed to be the major active ingredients. [3] Curcuminoids have been found to possess a variety of biological and pharmacological activities including antitumor, antioxidant, anti-inflammatory, anti-HIV, anti-Alzheimer's, anti-hepatotoxic and cardiovascular protection activities, [4 -10] leading to increased interest in recent years in this group of compounds.…”

Thirteen curcuminoids (1-13) were isolated from the rhizomes of Curcuma longa. Among them, 1,5-dihydroxy-1,7-bis(4-hydroxyphenyl)-4,6-heptadiene-3-one (1), 1,5-dihydroxy-1-(4-hydroxy-3-methoxyphenyl)-7-(4-hydroxyphenyl)-4,6-heptadiene-3-one (2), 1,5-dihydroxy-1-(4-hydroxyphenyl)-7-(4-hydroxy-3-methoxyphenyl)-4,6-heptadiene-3-one (3), and 3-hydroxy-1,7-bis-(4-hydroxyphenyl)-6-heptene-1,5-dione (4) are new compounds, and 1-(4-hydroxyphenyl)-7-(3, 4-dihydroxyphenyl)-1, 6-heptadiene-3, 5-dione (5) is isolated from natural sources for the first time. The structures of these compounds were elucidated by extensive spectroscopic analyses, especially 1D and 2D NMR spectroscopy. The (13)C NMR data and complete (1)H and (13)C NMR assignments of some known compounds are reported for the first time. In addition, the errors of (1)H and (13)C assignments reported in the literature were corrected.

“…The most usual methods for the microbial decontamination of vegetal material are based on applications of ethylene oxide or methyl bromide. However, both methods promote formation of toxic products and have been banned in many countries, such as Japan and those of the European Union [7].…”

“…These effects are caused by the interaction of ionizing radiation with water molecules, generating free radicals. In turn, these free radicals are highly reactive with different cell components, such as DNA, enzymes, and secondary metabolites (including EOs) [7]. Literature describes the effects of γ-radiation on the chemical composition of many vegetal species.…”

Abstractγ-Radiation provides an effective alternative method to reduce or eliminate microbial contamination of medicinal herbs and other plant materials. However, a search in the literature is important to describe the effects of γ-radiation on the content and integrity of secondary metabolites from plants. The present work provides a review of the effects of γ-radiation on extraction yields and chemical composition of essential oils isolated from roots, rhizome and cortex, leaves, fruits, seeds, flowers, and whole plant. In addition, this review describes the effects of γ-radiation on terpenes. The informations in the present work may assist in research about essential oils and dose of γ-radiation that is able to biologically decontaminate without causing chemical changes in secondary metabolites. These reports in the literature can describe the behavior of many of these metabolites when subjected to various doses of radiation.

“…Os principais compostos voláteis identificados por CHATTERJEE et al [5] na cúrcuma irradiada foram α-felandreno, p-cimeno, 1,8 cineol, β-cariofileno, arcurcumeno, zingebereno, β-sesquifelandreno, nerolidol, ar-turmerona, curlona e dehidrozingerona. Segundo GOVINDARAJAN [7], os compostos ar-curcumeno e arturmerona podem ser formados durante tratamentos tér-micos, aos quais a cúrcuma é submetida, podendo o arcurcúmeno também ser formado pela conversão do zingibereno e do β-sesquifelandreno durante o armazenamento.…”
