Figure 2 in Amino acids L-phenylalanine and L-lysine involvement in trans and cis piperamides biosynthesis in two Piper species
Figure 2. HPLC analysis of the enzymatic reactions (L-phenylalanine + enzymatic extract of P. tuberculatum leaves). Chromatogram A shows the formation of the cinnamic acid product after incubation of the amino acid L-phenylalanine with the enzymatic extract. Chromatogram B show the the blank for comparison (L-phenylalanine + enzymatic extract of P. tuberculatum leaves, previously treated with 6M hydrochloric acid for enzyme inactivation). Chromatogram C shows the retention time of the phenylpropanoid cinnamic acid (standard). In addition to the amino acidL-phenylalanine, L-tyrosine was also used as a possible precursor to phenylpropanoids, but no conversion to p-coumaric acid was observed.The same results were observed for P. arboreum.

Herbarium specimen image of Piper L., part of the collection of Naturalis Biodiversity Center
Part of a training dataset of scanned herbarium specimens. The data paper and a summary landing page will be published on Zenodo as it gets published.<br><br>Content of this deposition:<br><br>- A JSON-LD datafile listing the label data associated with this herbarium specimen. The Darwin and Dublin Core data standards are used for most values.<br>- A JPEG image file of the scanned herbarium sheet.<br>- Two PNG files containing segmented image overlays of the scanned herbarium sheet. The _all extension indicates that all labels, color charts and pieces of text have received a different color against a black background color. The _sel extension indicates that these elements are white if they're barcode labels, yellow if they're color charts and red if they're anything else.

Text-fig. 1. D&E tree of Endress and Doyle (2009), from the combined morphological and molecular analysis of Doyle and Endress (2000), with modifications based on more recent data, showing the inferred evolution of the reticulum grading character (39). Boxes under names of taxa indicate their character state; shading of branches indicates their reconstructed state based on parsimony optimization with MacClade (Maddison and Maddison 2003). Nymph = Nymphaeales, Aust = Austrobaileyales, Chlor = Chloranthaceae, Piper = Piperales, Ca = Canellales, Magnol = Magnoliales. in Early Cretaceous Monocots: A Phylogenetic Evaluation
