Research on aroma components in flowers and fruits of three varieties of jaboticaba
The flowers and fruits of three varieties of jaboticaba including ‘Saba’ (‘Sb’), ‘Sijizaosheng’ (‘Sjzs’) and ‘Fukuoka’ were used to determine the aroma components by using head space-gas chromatography-mass spectrometry (HS-GC-MS) technology. The results

Unimolecular Reactions of Peroxy Radicals Formed in the Oxidation of α-pinene and β-pinene by Hydroxyl Radicals [PDF]
Atmospheric oxidation of monoterpenes (emitted primarily by evergreen trees) is known to contribute to the formation and growth of aerosol particles. While recent research has tied the formation of organic aerosol to unimolecular chemistry of the organic
