“…The metabolite composition of seaweeds in this study was only quantitatively different from that derived from Xiapu city. Such a quantitative not qualitative difference has also been observed in other plants such as chamomile (Wang et al, 2004), Salvia miltiorrhiza Bunge (Dai et al, 2010), pistachios (Sciubba et al, 2014) and green coffee bean (Kwon et al, 2015).…”

Molecular nutrition study is essential for assessing food quality. Pyropia haitanensis is nutritious and delicious health food in southern China. Consumers prefer the first harvested P. haitanensis for its tender taste. To understand the comprehensive alteration in the nutrition of P. haitanensis with different harvest time, we characterized the metabolomic variations induced by harvest time using NMR spectroscopy coupled with multivariate data analysis.We found that harvest time was an important factor influencing the nutrient composition of P. haitanensis. The levels of glutamine, alanine, aspartate, taurine, and isofloridoside contained in seaweeds were significantly increased over the harvest time. These findings enhanced our understanding of the nutritional features of P. haitanensis harvested at different times and provided useful information on the quality assessment of P. haitanensis.

Phytochemical investigation on the florets of Thysanolaena latifolia leads to the isolation of a new compound 6″-O-acetylorientin-2″-O-α-L-rhamnopyranoside (1), named amrisoside and other 34 known compounds. The chemical structures of the compounds were determined from the interpretation of spectroscopic data including NMR, MS, and IR. This is the first report of phytochemical constituents from the monotypic genus Thysanolaena.

The analysis of metabolites contained in the male cones of Wollemia nobilis was investigated for the first time in this study. Several diterpenoids of chemosystematic relevance were recognized for the first time from the genus and/or from the Araucariaceae family, namely isocupressic acid (1), acetyl-isocupressic acid (2), methyl (E)-communate (3) and sandaracopimaric acid (4). All these terpenoids are also endowed with interesting biological activities and may play a primary role in the self defence toward herbivores. The presence of a new norlabdane (norlabda-8(16)-12-dien-14,17-diol) trivially named as wollemol (5) was also recognized. Norditerpenes are scarcely distributed in Plant Kingdom and in particular in Gymnosperms and this aspect was discussed. The structure of 5 was determined by extensive NMR analysis employing mono- and bidimensional experiments. The 7-4‴-dimethoxyagathisflavone (6), a biflavonoid already recognized in Araucariaceae and W. nobilis, was also isolated from male cones together with shikimic acid (7), a biogenetic precursor of polyphenolic compounds, besides carbohydrates such as glucose (8) and saccharose (9), and arginine (10) a quite common amino acid.
