Objectives: (1) Obtain complete genomic clones plus promoter regions of apple peel genes encoding HMGR isozymes HMG2 and HMG3 and determine whether expression of these genes is regulated by ethylene; (2) Demonstrate function of the gene product and obtain a genomic clone of the ethyleneresponsive promoter of the putative apple α-Farnesene Synthase gene; (3) Determine correlation among ethylene-...

A new HPTLC method has been developed for the identification and quantification of ursolic acid in apple peel extract. Ursolic acid can be easily estimated after derivatization with Liebermann TABLE 1: RECOVERY STUDY OF URSOLIC ACID FROM MALUS DOMESTICA PEEL Amount spotted (μg) Peak area (AU) Amount detected (μg) RSD (%) Accuracy (%) 0.91 4098.7 0.91 1.12 100.9 1.14 4677.5 1.13 1.48 99.6 1.36 5...

Sugar apple (Annona squamosa L.) is a popular tropical fruit and its peel is a municipal waste. An ultrasound-assisted extraction method was developed for the recovery of natural antioxidants from sugar apple peel. Central composite design was used to optimize solvent concentration (13.2%-46.8%), ultrasonic time (33.2-66.8 min), and temperature (43.2-76.8 °C) for the recovery of natural antioxi...

Several ancient apple varieties and a wild apple variety grown in Croatia were analysed for the polyphenol content and compared to two varieties grown in USA. In the flesh, flavanols, dihydrochalcones and phenolic acids (24 to 137, 23 to 109, 3 to 238 mg kg 1 of fresh weight (FW), respectively) were found. Peel contained flavanols, dihydrochalcones, phenolic acids, flavonols and anthocyanins (6...

The objective of this study is to investigate the effects of irradiation from light-emitting diodes (LEDs) on several fruits during storage. To improve storage and increase the contents of some bioactive compounds, apple, tomato and red bell pepper fruits were exposed to yellow light emitted from the diodes at 590 nm. The contents of ascorbic acid, total phenolics, total flavonoids and several ...

Duodenal atresia is rarely associated with situs inversus abdominus. We report a case of duodenal atresia associated with small bowel atresia of apple peel type and situs inversus abdominus.

Apples (Malus domestica Borkh.) have been identified as one of the main dietary sources of antioxidants, mainly phenolic compounds. These compounds vary in their composition and concentration, among cultivars and fruit tissues. In this research, the total phenolic content (Folin-Ciocalteau assay), antioxidant capacity (Ferric Reducing Antioxidant Power, FRAP assay) and mineral composition in th...

Apple (Malus×domestica Borkh) is among the main sources of phenolic compounds in the human diet. The genetic basis of the quantitative variations of these potentially beneficial phenolic compounds was investigated. A segregating F₁ population was used to map metabolite quantitative trait loci (mQTLs). Untargeted metabolic profiling of peel and flesh tissues of ripe fruits was performed using li...

Consumption of fruits and vegetables has been shown to be effective in the prevention of chronic diseases. These benefits are often attributed to the high antioxidant content of some plant foods. Apples are commonly eaten and are large contributors of phenolic compounds in European and North American diets. The peels of apples, in particular, are high in phenolics. During applesauce and canned ...
