Identification of flavonol glycosides in American cranberry fruit

Two flavonol glycosides, quercetin galactoside and quercetin arabinoside, have been identified in American cranberry fruit, as a complementary investigation of our previous study. The analysis processes included separation, hydrolysis and structure elucidation of flavonol glycosides. The separation of flavonol glycosides was carried out by solvent extraction, thin-layer chromatography (TLC) and high performance liquid chromatography (HPLC). After hydrolysis of the obtained flavonol glycosides, flavonol aglycones and sugars were identified by HPLC and gas chromatography–mass spectrometry (GC–MS), respectively.

Changes of flavonol synthase and flavonol contents during grape berry development

Flavonols as an important kind of flavonoids not only have many defense-related functions, but also play an important role as potent antioxidants. Flavonol synthase (FLS) as the key enzyme in flavonol synthesis determines the final contents of flavonols in plant materials. The objective of this work was to study the changes of total flavonol content, free flavonol content, the individual flavonol aglycone contents and the two flavones (luteolin and apigenin) contents during grape berry development. The activity and the amount of the changes of FLS during grape berry development were also estimated. The results showed that quercetin, myricetin, kaempferol, isorhamnetin and galangin were detectable during grape berry development, and quercetin aglycone predominated in the total flavonol content in rapid growth phase, lag growth phase and the latter part of the ripening phase, myricetin aglycone witnessed a great increase at veraison, although kaempferol, isorhamnetin and galangin only accounted for a little part of the total flavonol contents but their individual contents all increased after veraison and kaempferol witnessed its highest content at the ripening phase. When it came to the contents of total phenols, total flavonoids, total flavonols and free flavonols, all of them showed accumulated peaks at both the rapid growth phase and the ripening phase. The result of FLS activity had a highly positive correlation with the total contents of flavonols, and the immunoblotting analysis detected two proteins whose signal intensities were in accordance with the FLS activities.     

Mutagenic Flavonol Aglycones in Infusions and in Fresh and Pickled Vegetables

Free flavonol aglycones, potentially mutagenic, were determined in vegetable infusions, in fresh and pickled vegetables and in vegetables exposed to mold growth. None of the infusions tested contained any considerable amount of free mutagenic aglycones, but some vegetables, such as red onions and cucumbers, had appreciable amounts of free flavonol aglycones, especially in the external layers. The treatment used in the production of pickled vegetables did not change the quality and quantity of the flavonols but the presence of molds altered the quantity of flavonol aglycones and glycosides.     

Flavonol profile of cactus fruits (Opuntia ficus-indica) enriched cereal-based extrudates: Authenticity and impact of extrusion

In previous studies, it was hypothesized that isorhamnetin glycosides are the dominant flavonol derivatives occurring in the peels and cladodes of cactus Opuntia ficus-indica fruits and might be used as markers for analyzing the authenticity of food products containing (whole) cactus fruits or cladodes. In the present work, use of the whole yellow-orange fruit from cactus O. ficus-indica as an ingredient of rice- and corn-based snacks was evaluated. The impact of extrusion cooking on the flavonol profile was characterized in rice- and corn-based extruded products fortified with a freeze-dried preparation from the whole cactus fruit. HPLC analysis showed that the flavonol profile of cactus O. ficus-indica consisted of five prominent isorhamnetin glycosides with a concentration of 148.9 μg/100 mg dw. In contrast, the rice or corn grits used in the present study did not contain any flavonol at all. The freeze-dried fruit was added in different ratios (0, 2, 6, and 10%) to the rice or corn grits prior to the extrusion process. Analysis of the final extrusion products showed that flavonol profiles from the fortified rice or corn products, even at the lowest level of addition (2%), were similar to the original profile of the fruit before processing. Furthermore, the total flavonol content in extruded products was not significantly affected by extrusion cooking. This study showed that the unique flavonol profile of fruits from cactus O. ficus-indica might serve as a biochemical marker for the evaluation of the authenticity of products made from whole cactus fruit or the fruit's peel.

Potential interaction of Ginkgo biloba leaf with antiplatelet or anticoagulant drugs: what is the evidence?

Some writers hold the view that the combination of Ginkgo biloba with anticoagulant or antiplatelet drugs represents a serious health risk. Such concerns are largely based on the assumption that Ginkgo has clinically relevant antiplatelet activity, as well as accounts of bleeding episodes associated with Ginkgo consumption. To investigate whether these bleeding episodes have a pharmacodynamic, idiosyncratic or coincidental basis, a review of controlled clinical studies and case reports was undertaken. Results from controlled studies consistently indicate that Ginkgo does not significantly impact haemostasis nor adversely affect the safety of coadministered aspirin or warfarin. Most of these studies were undertaken using EGb 761, a well-defined extract of Ginkgo biloba. In contrast, EGb 761 has not generally been implicated in the case reports. In general, the quality of these case reports is low. Nevertheless, the possibility of an idiosyncratic bleeding event due to Ginkgo use cannot be excluded on the basis of the available information. However, there is scant information from case reports or controlled trials to support the suggestion that Ginkgo potentiates the effects of anticoagulant or antiplatelet drugs. Such high-level safety concerns for this herb are deemed to be unsupported by the currently available evidence.
