<strong>SECTION</strong> 3 <strong>PLANT</strong> <strong>METABOLOMICS</strong><br />
Section leader R. Verpoorte<br />
GENERAL INTRODUCTION<br />
Plants produce a wide range of secondary metabolites. These plant<br />
specific compounds represent very important quality traits of plants.<br />
They are involved in defense against pests and diseases and responsible<br />
for color, taste, flavor and health effects of our food. Many secondary<br />
metabolites are economically important fine chemicals such as drugs,<br />
flavors, fragrances, dyes, antioxidants and insecticides.<br />
The Pharmacognosy group has as mission:<br />
‘To find, produce and determine the role of economically important<br />
secondary metabolites in plants and unravel their biosynthesis, and to<br />
create an international academic ambiance in which students can be<br />
trained in multidisciplinary projects related to these goals to become<br />
creative and independent researchers’.<br />
In terms of research this is translated to projects on understanding the<br />
role of secondary metabolism in plants, on finding new leads for drug<br />
development, and on the biosynthesis of secondary metabolites, with the<br />
aim to improve their production in plants, plant cell cultures or<br />
microorganisms by using genetic engineering. For mapping biosynthetic<br />
pathways, a metabolomics approach is developed. The metabolic<br />
engineering project is carried out in close collaboration with the Section<br />
Plant Physiology (Prof.Dr. J. Memelink, Dr. H.J.M. Linthorst). The<br />
section has established a platform for metabolic profiling, which, among<br />
others, is applied as a tool in studying plant-insect and plant-fungal<br />

interactions, together with the sections Plant Physiology and Plant<br />
Ecology (Dr. P.G.L. Klinkhamer, Prof.Dr. E. van der Meijden). NMRspectrometry<br />
is the major tool for these metabolomics projects.<br />
In connection with the educational activities the department has<br />
particularly many MSc- and PhD-students from 2nd and 3rd world<br />
countries working on projects related to the exploration of their very<br />
rich biodiversity.<br />
Research themes:<br />
1. Leadfinding<br />
2. Cannabis<br />
3. Isolation Natural Products<br />
4. Metabolomics<br />
1. Leadfinding<br />
In this project the effect of various plant extracts are studied for<br />
antimicrobial activity and in particular the effect against wood rot fungi.<br />
Several active compounds were isolated and identified from saw dust of<br />
tropical hardwoods. In a joint project with some industrial partners and<br />
Indonesia we are working on the isolation of compounds that have an<br />
anti-obesitas effect. In collaboration with the division of Medicinal<br />
Chemistry (LACDR) we work on the isolation of compounds which<br />
have activity on the adenosine or opioid receptors.<br />
2. Cannabis<br />
Studies on medicinal cannabis are performed in an STW-project with<br />
three Dutch companies, Feyecon, Farmalyse and Enzyscreen, and the<br />
Delft University of Technology. Our research includes the isolation of<br />
cannabinoids by using centrifugal partitioning chromatography. All<br />
major cannabinoids can now be produced in larger (gram) quantities and<br />
are made available commercially. The production will be further<br />
developed for GMP-conditions in the STW project. In collaboration<br />
with Enzyscreen bacterial strains have been found that can produce<br />
novel cannabinoids derivatives.<br />
Studies on the inhalation and the oral administration of medicinal<br />
cannabis tea have resulted in improved protocols, which will be very<br />
helpful for patients using the legal standardized medicinal cannabis.<br />

3. Isolation Natural Products<br />
A large grant from Mibiton enabled the department to invest in<br />
centrifugal partitioning chromatography (CPC) and LC-MS equipment.<br />
This grant was obtained in close collaboration with several companies<br />
(Feyecon, Farmalyse, Xenobiosis, Holland Biodiversity and<br />
Enzyscreen) that recently have combined their complementary expertise<br />
and marketing efforts in a new start-up company PRISNA (Product<br />
Isolation from Nature). The CPC will be used, among others, for the<br />
isolation of cannabinoids and hop bitter compounds. For the latter we<br />
developed a completely novel large scale, food compatible separation<br />
method for the cis- and trans-iso-alpha acids, the compounds<br />
responsible for the bitter taste of beer.<br />
4. Metabolomics<br />
In the past 7 years we have developed NMR as a tool for metabolomics<br />
studies. The NMR offers the great advantage of a very reproducible<br />
method for metabolome analysis, which is very easy to quantify, not<br />
requiring any calibration curves as for all compounds the 1 H-NMR<br />
signals are only dependent on the molar concentration. In the mean time<br />
we have built up a library of both 1D and 2D spectra of more than 500<br />
common plant metabolites all run under strictly defined conditions.<br />
Moreover we have more than 20,000 spectra of plants all recorded<br />
following standard protocols, which can thus be used for data-mining.<br />
This database concerns mainly plant and plant cell cultures of<br />
Catharanthus roseus, and plants such as Arabidopsis, Brassica rapa<br />
(IOP Genomics project with Universities of Wageningen and<br />
Groningen), Senecio, tobacco, vanilla, Ilex species (including herba<br />
mate), tomatoes (ERA-PG project), and wine and grapewines (ERA-PG<br />
project) for studies of functional genomics, biosynthesis and resistance<br />
against pests and diseases. Metabolomics for quality control and the<br />
pharmacological activities is applied on some medicinal plants, e.g.<br />
Ephedra, Ginseng, Gingko and licorice preparations.<br />
By NMR in a single operation both primary and secondary metabolites<br />
can be determined. Particularly 2D-NMR spectrometry methods have<br />
been shown to be very useful for simplifying the spectra (2D-J-resolved<br />
projected spectra) and structure elucidation in complex extracts (e.g.<br />
2D-J-resolved, HMBC, HMQC, COSY). In the coming years we will<br />
collaborate with the LUMC to further build up our library of natural<br />
products NMR spectra and exchange experience in field of NMR-based<br />
metabolomics in various organisms. In a collaborative project with<br />

Institute of Biology<br />
Qiagen, supported by a European grant, we will develop standardized<br />
methods for sample preparation in metabolomics (the pre-analytical<br />
phase).<br />
In retrobiosynthetic studies we have shown that salicylate and 2,3-<br />
dihydroxybenzoic acid in Catharanthus roseus are derived from the<br />
isochorismate branch of the chorismate pathway rather than from the<br />
phenylalanine branch. Though both compounds are formed immediately<br />
after elicitation, the total incorporation levels in both differ, showing<br />
that the development of fluxomics is important to really understand the<br />
regulation of biosynthetic pathways. The development of fluxomics for<br />
plants will thus be a major target for the coming period.<br />
