In the present study, an integrated approach combining HPLC/DAD, GC/MS, near infrared (NIR) spectroscopy, and chemometrics was used to geographically discriminate saffron samples from Iran and China. Chinese and Iranian samples can be well-separated based on HPLC data analysed by a principal component analysis and an orthogonal partial least squares discriminant analysis. Picrocrocin and two types of crocins were found to be the discriminating variables, and the Chinese samples had higher contents of safranal and picrocrocin but lower cis-crocin 3Gg, kaempferol-3-O-sophoroside and isophorone...

Saffron (Crocus sativus L.) is one of the most expensive spices in the world due to its medicinal and aromatic value. However, saffron production is severely affected by the corm rot disease throughout the saffron producing countries. In this study, we report a basidiomycetous latent pathogen of saffron, designated as CSE26, capable of producing phytotoxic compounds. CSE26 is a highly odorous basidiomycete with monomitic hyphal system. Molecular phylogeny of ITS and 28S ribosomal gene sequence of CSE26 assigned it as Porostereum spadiceum...

A new aromatization method for olive oils with saffron aqueous extracts rich in safranal has been developed using liquid-liquid extraction. Four flavoured olive oils were obtained (SO1-SO4). SO1 showed the highest safranal concentration (145.89 mg L-1 ), followed by SO2 (79.33 mg L-1 ), SO3 (0.30 mg L-1 ) and SO4 (0.01 mg L-1 ). Although flavouring originated a decrease in the quality parameters and the oxidative stability of the oils, even after 7 months of storage, at room and refrigeration temperatures, the oil parameters evaluated were still comparable to those of extra virgin olive oil...

Oxidative stress and excessive nitric oxide (NO) production play considerable roles in infarction-induced injury impairing cardiac functions. Crocin is the active constituent of Crocus sativus (saffron) with antioxidant properties and has protective effects against disturbances induced by ischemia in many organs. The present study aimed to investigate the protective effects and the underlying mechanisms of crocin on myocardial infarction (MI)-induced injury in rats in vivo. MI rats were intraperitoneally injected with crocin at different doses for seven successive days after coronary ligation...

Anxiety and depression are prevalent among cancer patients, with significant negative impact. Many patients prefer herbs for symptom relief to conventional medications which have limited efficacy/side effects. We identified single-herb medicines that may warrant further study in cancer patients. Our search included PubMed, Allied and Complementary Medicine, Embase, and Cochrane databases, selecting only single-herb randomized controlled trials between 1996 and 2016 in any population for data extraction, excluding herbs with known potential for interactions with cancer treatments...

Crocins, the red soluble apocarotenoids of saffron, accumulate in the flowers of Crocus species in a developmental and tissue-specific manner. In Crocus sieberi, crocins accumulate in stigmas but also in a distinct yellow tepal sector, which we demonstrate contains chromoplast converted from amyloplasts. Secondary metabolites were analysed by LC-DAD-HRMS, revealing the progressive accumulation of crocetin and crocins in the yellow sector, which were also localized in situ by Raman microspectroscopy. To understand the underlying mechanisms of crocin biosynthesis, we sequenced the C...

Objective: Epidural blood patch is the procedure of choice to relieve postdural puncture headache. Hydroxyethyl-starch (HES) has been proposed as a patch in some circumstances such as in the case of hematological disease due to the theoretical risk of neoplastic seeding to the central nervous system. Acute neurological HES toxicity has been excluded by a previous animal study, but the long-term neurological toxicity has not been evaluated. Methods: Rats were randomly assigned to one of three groups: no intrathecal injection, 20 μL of intrathecal saline, or a 20-μL intrathecal HES (6% hydroxyethyl starch 130/0...

Histological examination of the rat placenta and fetus is uncommon. Toxicological studies mainly rely on gross examination of the fetus and on fetal and placental weights. These are often insufficient to assess the fetal and placental toxicity of xenobiotics. The small size of the fetus makes its dissection labor-intensive. Thus, our objective was to develop a simple and accurate technique to evaluate the rat fetus and placenta. Sprague-Dawley rat fetuses at gestational day 19.5 ( n = 18) and their placentas ( n = 32) were fixed in formalin...

Signal transducer and activator of transcription 3 (STAT3) is involved in the survival, proliferation, angiogenesis, invasion and metastasis of tumor cells. In addition, interleukin-6 (IL-6) has been reported to be closely related to STAT3 activity. In the present study, we investigated whether crocin, a major glycosylated carotenoid derived from saffron, can modulate the IL-6/STAT3 pathway to induce growth inhibition and sensitivity to cancer cell apoptosis. We determined that crocin inhibited STAT3 activation induced by IL-6 in hepatocellular carcinoma Hep3B and HepG2 cells...

Saffron extracts have a long history of application as skin protectant, possibly due to their ability to scavenge free radicals. In this work, the performance of a hydrogel enriched with antioxidant compounds isolated from saffron crocus (Crocus sativus L.) petals was tested. These hydrogels could be considered as new drug delivery system. Hydrogels are crosslinked polymer networks that absorb large quantities of water but retain the properties of a solid, thus making ideal dressings for sensitive skin. We tested antioxidant-enriched hydrogels on primary mouse fibroblasts...

Saffron, the dried red stigmas of Crocus sativus L. plant, is the most expensive spice in the world. It is highly valued not only for the color and flavor that exerts to various foods and drinks but also for its functional properties. Various classes of apocarotenoids such as crocetin sugar esters, picrocrocin and safranal are responsible for these characteristics. In the present review, the evolution of the methods proposed by the ISO standard for extraction and determination of saffron apocarotenoids since 1980 is presented in parallel to other approaches proposed by various scientists to overcome limitations of the standard...
