The essential oils of Citrus sinensis and Citrus latifolia showed antimycotic activity against Candida spp. isolated from the oral cavity; they are neither mutagenic on the Ames test nor cytotoxic. Their main components are R-(+)-limonene, β-thujene, α-myrcene and γ-terpinene. The aim of this work
Abstract: The interest towards nutraceuticals able to counteract drug side effects is continuously growing in current chemotherapeutic protocols. In the present study, we demonstrated that smoothies containing mixtures of Citrus sinensis and Vitis vinifera L. cv.
Polymethoxyflavones (PMFs) from citrus genus have been of particular interest because of their broad spectrum of biological activities, including antiinflammatory, anticarcinogenic, and antiatherogenic properties. There have been increasing interests in the exploration of health beneficial
Background: During the last decades, a huge body of evidence has been accumulated suggesting that Citrus fruits and their juices might have a role in preventing many diseases including cancer. Objective: To summarize the numerous evidences on the potential of Citrus juices and their extracts as
A number of essential oils derived from plants are claimed to have several medicinal functions, including anti-cancer and anti-inflammation effects. However, the chemical composition and biological activities of flower-derived components have not been sufficiently characterized. Therefore, we
Polymethoxyflavones (PMFs) from citrus genus are of particular interest because of their broad spectrum of biological activities, such as anti-inflammatory, anti-carcinogenic, and anti-atherogenic properties. Recently, the exploration into the beneficial health properties of PMFs in citrus fruits
It is known that nobiletin possesses anticancer, antiviral and anti-inflammatory activities. Recently, the demand for nobiletin in large quantities and high purity has increased. However, conventional normal-phase silica gel chromatography and C(18)-reverse-phase separation methods cannot satisfy
Nobiletin (NOB), a polymethoxylated flavone found in sweet orange (Citrus sinensis) peel, is currently recognized as a promising anti-inflammatory and anti-tumor agent. It is believed that, by undergoing metabolic biotransformation in vivo, nobiletin is demethylated by hepatic P450 enzymes, yielding
Fifteen polymethoxyflavones (PMFs) and hydroxylated PMFs were isolated from sweet orange (Citrus sinensis) peel extract and synthesized to investigate their biological activity. All obtained compounds were tested in HL-60 cancer cell proliferation and apoptosis induction assays. While some PMFs and
Flavonoids, polyphenolic phytochemicals which include flavones and isoflavones, are present in the common human diet. It has been suggested that these compounds may exert anticancer activity; however, the mechanisms involved remain unknown. We have recently shown (Sergeev, 2004, Biochem Biophys Res
P-glycoprotein (P-gp), a membrane transporter encoded by the MDR1 gene in human cells, mediates drug efflux from cells and plays a major role in causing multidrug resistance; which is one of the most accepted mechanisms for failure of chemotherapy in cancer treatment. In this study, we investigated
The O-methylation of various secondary metabolites is mainly catalyzed by S-adenosyl-l-methionine (SAM)-dependent O-methyltransferase (OMT) proteins that are encoded by the O-methyltransferase gene family. Citrus fruits are a rich source of O-methylated flavonoids that have a broad spectrum of
In recent years, there has been increasing public interest in plant antioxidants, thanks to the potential anticarcinogenic and cardioprotective actions mediated by their biochemical properties. The red (or blood) orange (Citrus sinensis (L.) Osbeck) is a pigmented sweet orange variety typical of
BACKGROUND
Hesperidin is a flavonoid that has various pharmacological activities including anti-inflammatory, antimicrobial and antiviral activities.
OBJECTIVE
The aim of the study is the isolation of hesperidin from the peel of Citrus sinensis L. (Rutaceae), and the evaluation of its antioxidant
The in vitro cytotoxic activity on human cancer cell lines of sixteen commercial EOs such as Aloysia triphylla , Boswellia carterii , Boswellia serrata , Cinnamomum zeylanicum , Cistus ladanifer , Citrus × aurantium , Citrus limon , Citrus sinensis , Cymbopogon citratus , Foeniculum vulgare ,
