Inhibition of Breast Cancer Cell Proliferation and In Vitro Tumorigenesis by a New Red Apple Cultivar.

Purpose: The aim of this study was to evaluate the antiproliferative activity in breast cancer cells and the inhibition of tumorigenesis in pre-neoplastic cells of a new apple cultivar with reddish pulp, called the Pelingo apple.

Methods: The antiproliferative activity was evaluated in MCF-7 and MDA-MB-231 human breast cancer cells. The inhibition of tumorigenesis was performed in JB6 promotion-sensitive (P+) cells.

Flowers volatile profile of a rare red apple tree from Marche region (Italy).

In this paper, the volatiles emitted by flowers and various parts of the flower of a rare spontaneous Italian red (peel and flesh) apple named "Pelingo", were analyzed by SPME with the aim of identifying the contribution of each one to the whole aroma profile. Linalool was the most abundant volatile of flowers: from 43.0% in the flower buds, to 17.

Polyphenols profile and antioxidant activity of skin and pulp of a rare apple from Marche region (Italy).

Background: Apples are an important source of polyphenols in the human diet and the consumption of this fruit has been linked to the prevention of degenerative diseases.

Results: CATECHINS, PROCYANIDINS, HYDROXYCINNAMIC ACIDS, FLAVONOL GLYCOSIDES, DIHYDROCHALCONE GLYCOSIDES AND ONE ANTHOCYANIN: cyanidin-3-O-galactoside, were identified both in the peel and pulp. Procyanidins, catechins and flavonols represent the main constituents of peel.

Geographical traceability of Italian white truffle (Tuber magnatum Pico) by the analysis of volatile organic compounds.

Results are presented that were obtained on the geographic traceability of the white truffle Tuber magnatum Pico. Solid-phase microextraction coupled to gas chromatography/mass spectrometry (SPME-GC/MS) was employed to characterize the volatile profile of T. magnatum white truffle produced in seven geographical areas of Italy.
