Analysis of Volatile Components of Cape Gooseberry (Physalis peruviana L.) Grown in Turkey by HS-SPME and GC-MS
Volatile components in cape gooseberry fruit at ripe stage were collected using headspace-solid phase microextraction, and analyzed by gas chromatography-mass spectrometry. Three solid phase microextraction fiber coatings (DVB/CAR/PDMS, CAR/PDMS, and PDMS/DVB) were tested for evaluation of volatile compounds. DVB/CAR/PDMS fiber showed a strong extraction capacity for volatile compounds and prod...
متن کاملAnalysis of the volatile components of five Turkish Rhododendron species by headspace solid-phase microextraction and GC-MS (HS-SPME-GC-MS).
Volatile constituents of various solvent extracts (n-hexane, CH2Cl2, H2O) of 15 different organs (leaves, flowers, fruits) of five Rhododendron species (Ericaceae) growing in Turkey were trapped with headspace solid-phase microextraction (HS-SPME) technique and analyzed by GC-MS. A total of 200 compounds were detected and identified from organic extracts, while the water extracts contained only...
متن کاملRecent Advances in Microextraction Methods for Sampling and Analysis of Volatile Organic Compounds in Air: A Review
Human exposures to volatile organic compounds (VOCs) are associated with a wide range of health problems. Due to these adverse effects of VOCs on the human health, determination of trace levels of VOCs is very important for accurate assessment of indoor and outdoor exposure. Solid phase microextraction (SPME), needle trap device (NTD) and hollow fiber- liquid phase microextraction (HF-LPME) are...
متن کاملVolatile Oil Constituents of the Eucalyptus viridis R. T. Baker and Eucalyptus oleosa F. Muell. Leaves from Iran
Background: The genus Eucalyptus (family Myrtaceae) comprises well-known plants of over 600 species of trees. Although most of the plants are native to Australia, numerous species have been introduced to other parts of the world, including Iran, as economic and ornamental trees in forest trial provenances, where the plants have become source of important fast-growing hardwood trees and Eucaly...
متن کاملOptimizing Sourdough Processing for the Production of ɣ-nonalactone (Fruity Aroma) by Lactobacillus sanfranciscensis Using Headspace Solid-Phase Microextraction Method
Background and Objectives: Sourdough processing is a well-known method to improve food flavor. One of the most important lactic acid bacteria isolated from sourdoughs is Lactobacillus sanfranciscensis. Because of the bacterial ability for acidification and liberation of the volatile compound precursors, it can strongly affect dough rheology and aromatic properties. In this study, the best condi...
