Differential Distribution of Flavonoids and Phenolic Acids in Leaves of Kalanchoe delagoensis Ecklon & Zeyher (Crassulaceae)

Abstract

Abstract

Phenolic profiling and in vitro bioactivities of three medicinal Bryophyllum plants

“…The presence of anthocyanins in the leaves of Bryophyllum spp. might be responsible for the dark, pigmented strands located in the abaxial leaf surface of these plants, as suggested by other authors (Casanova et al, 2020). This hypothesis is reinforced by the presence of idioblasts found in the leaf structure of B. daigremontianum and B. tubiflorum, considered cell reservoirs for phenolic compounds (Casanova et al, 2020;Chernetskyy et al, 2018).…”

Mass spectrometry imaging and single-cell transcriptional profiling reveal the tissue-specific regulation of bioactive ingredient biosynthesis in Taxus leaves

“…Downregulation of terpenoid biosynthesis genes has been shown to be a useful approach to improving the production of taxol ( Oksman-Caldentey and Inze, 2004 ). Flavonoids and phenolic acid derivatives are important photo-protective compounds and antioxidants ( Casanova et al., 2020 ). Significantly, phenolic acid and flavonoid metabolism–related genes are specifically expressed in leaf EP cells and stomatal complex cells.…”

A Long-Term Study on Chemical Compounds and Their Location in Sweet Basil Leaves from Organic and Conventional Producers

“…In the present literature, only a few experiments were conducted with the distribution of phenolic and carotenoid compounds in plant tissues, but not with basil, especially in comparison between organic and conventional plants. Because the organic cultivation system yields different quantities in plant composition, we want to investigate the distribution of compounds in plant tissues [27,28]. The main aim of the present experiment was to show differences in the chemical composition of organic and conventional basil in three years of cultivation.…”
