Mass spectroscopy of natural products. XVIII Mass spectral studies of clavine alkaloidsThe fragmentation behaviour of clavine alkaloids is discussed in relation to the influence of the ring D structure. The appearance of significant ions is correlated with structural features of clavines. Using linked...
Natural products (NPs), are broadly defined as chemicals produced by living organisms. More precise definitions of NPs exist, but they do not always meet a consensus: some of the NPs include all small molecules that result from metabolic reactions, others classify as “NP” only products of se...

The natural interactions between plant roots and their rhizospheric microbiome are vital to plant fitness, modulating both growth promotion and disease suppression. In rice (Oryza sativa), a globally important food crop, as much as 30% of yields are lost
3.4.2. Solid State NMR Based Metabolomics Another exciting application of NMR spectroscopy is the analysis of semi-solid samples such as fresh plant leaf or intact tissues via the implementation of high resolution solid state magic angle spinning (HR-MAS) NMR [147]. In this tech...
Biosynthetic processes for plant-based terpenes, as the plastic pathway for the synthesis of the monoterpene, diterpenes, and tetraterpenes for methyl methylrithritol phosphates (MEP). The first cytosolic corrosive Melavonic acid (MVA) route is connected to sesquiterpene and triterpene. The first, ...
It was further found that reflectance spectra with a 5 nm spectral resolution are adequate to capture the spectral SICF feature at 761 nm. These preliminary results suggest that (761 nm) need to be explored more for future applications in optically complex coastal and inland waters....
Mulberry Diels–Alder-type adducts (MDAAs) are unique phenolic natural products biosynthetically derived from the intermolecular [4 + 2]-cycloaddition of dienophiles (mainly chalcones) and dehydroprenylphenol dienes, which are exclusively distributed in moraceous plants. A total of 166 MDAAs with...
