Amaryllidaceae alkaloids are a group of specialized metabolites found predominantly in the Amaryllidaceae plant family. Approximately 600 naturally occurring Amaryllidaceae alkaloids have been identified, many of which possess a variety of potent biological and pharmacological properties. However, only the ...
alkaloids, and other nitrogen-containing compounds (vindoline, camptothecin, steroidal glycoalkaloids, and glucosinolates) in plants. Certain SM, such as carotenoids and anthocyanins, are produced in a wide range of plants, while others, such as vindoline and camptothecin, are ...
Plants in general in their natural environment are nitrogen limited; therefore the sacrifice of valuable nitrogen fixed into alkaloids which generally have no apparent turnover but rather are dead end products is justified only by the fact that these metabolites serve important ecochemic functions for...
The metabolism of [8-14C]adenine and [8-14C]hypoxanthine in four species of Camellia plants was investigated in relation to the synthesis of purine alkaloids, caffeine and theobromine. Young leaves of C. sinensis had the ability to synthesize caffeine, but in C. irrawadiensis , these labelled...
However, information is limited on their involvement in the biosynthesis of specialized metabolites in plants, including Catharanthus roseus that produces a number of pharmaceutically valuable, bioactive terpenoid indole alkaloids (TIAs). Using small RNA-sequencing, we identified 181 conserved and 173 ...

The Biosynthesis of Nicotine and Related Alkaloids in Intact Plants, Isolated Plant Parts, Tissue Cultures, and Cell-Free Systems 来自 Springer 喜欢 0 阅读量: 47 作者: E Leete 摘要: Nicotine (1) (Figure 1) is the most common alkaloid found in the Nicotiana species (Solanaceae family) and ...
In this article, we review recent advances in the elucidation of biosynthesis of specialized metabolites in medicinal plants, including phenylpropanoids, terpenoids and alkaloids. These natural products may share a common upstream pathway to form a limited numbers of common precursors, but are ...
Plants synthesize numerous alkaloids that mimic animal neurotransmitters1. The diversity of alkaloid structures is achieved through the generation and tailoring of unique carbon scaffolds2,3, yet many neuroactive alkaloids belong to a scaffold class for
The biosynthesis and metabolism of purine alkaloids in leaves ofCamellia ptilophylla (cocoa tea), a new tea resource in China, have been investigated. The major purine alkaloid was theobromine, with theophyllinealso being present as a minor component. Caffeine was not accumulated in detectable quant...
