This study aimed to investigate the effects of ultra-long-term fermentation on formation non-volatile metabolites Chinese solid-fermented kohlrabies. Liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) based non-targeted metabolomics coupled with multivariate statistical analysis were employed respectively analyze kohlrabies solid fermented for 5 years (5Y), 8 (8Y), and 11 (11Y...

Chios Mastic Gum (CMG) and Oil (CMO) are two unique products of the tree Pistacia lentiscus var. Chia, cultivated exclusively on Greek island Chios. In present study, method proposed by European Pharmacopoeia for mastic identification was employed using HPTLC together with an in-house method. A GC-MS methodology also developed chemical characterization CMOs. α-Pinene β-myrcene were found in abu...

From the stems of Liriodendron tulipifera, seventeen known compounds have been extracted, isolated and purified. By using spectroscopic analysis, the structures of these pure constituents were determined as three lignans, four steroids and ten benzenoids. Identified compounds were screened for antioxidant abilities using: 1,1-diphenyl-2-picrylhydrazul (DPPH) and 2,2'-azino-bis(3-ethylbenzothi...

In which cells of the flower volatile biosynthesis takes place is unclear. In rose and snapdragon, some enzymes of the volatile phenylpropanoid/benzenoid pathway have been shown to be present in the epidermal cells of petals. It is therefore generally believed that the production of these compounds occurs in these cells. However, whether the entire pathway is active in these cells and whether i...
