A ONE DAY SYMPOSIUM FOCUSSING ON ADVANCES IN NATURAL PRODUCT ANALYSIS

Feb 25 2014

'SEPARATING THE WHEAT FROM THE CHAFF' at SYNGENTA RESEARCH LABS ON 9th APRIL 2014.

Towards High Peak Capacities in Fluid-based Separation Techniques for Natural Product Analysis

In this contribution, routes to high efficiency and high peak capacity will be discussed from a theoretical and a practical point of view.

The possibilities to increase on peak capacity in one-dimensional liquid chromatography (LC) and supercritical fluid chromatography (SFC) will be addressed. By combining two orthogonal separation mechanisms in a comprehensive approach i.e. LC×LC and SFC×LC unprecedented features allow to separate the most complex natural samples. The robustness of the presented techniques will also be highlighted.

Chromatographic and statistical tools to inform the safety risk assessment of natural products (paul.j.russell@unilever.com)Consumer interest is growing in food and cosmetic products which contain botanicals as an ingredient with an established or perceived functional benefit.  These materials are often intrinsically linked to traditional medicine cultures throughout the world.  Due to their inherent chemical complexity there are substantial challenges in safely commercialising truly efficacious plant derived materials capable of supporting strong functional claims.  Chemical understanding of natural products is critical to enable effective safety risk assessment and chromatographic based analytical methods have a key role to play to inform on chemical composition.

Traditional medicine based history of used is well documented for many natural products, but can only be used to support development programmes where both the indication and extract composition are the same as those historically used.  This should be confirmed through raw material authentication and holistic fingerprinting approaches, the latter of which we define as a ‘unique visual pattern representing the presence of known and/or unknown characteristic chemical components. 

The reductive nature of pharmacopeia marker approaches does not provide sufficient insight into the composition of the complex material as a whole and the concept of a holistic analytical representation also retains respect for the synergistic philosophy of completeness that is embedded in many traditional therapies.  Therefore recently there has been increased recognition of the value that chromatographic chemical fingerprinting can bring to naturals research through its use as a quality control tool.  However, the effectiveness of this approach is limited by the quality of the fingerprint obtained.  Here, examples of novel chromatographic methodology and linking data to chemometric approaches [1] in support risk assessment of partially or heavily refined extracts will be discussed.

Impact odourants in natural products-:- How to know what the nose knows

The techniques and applications in detecting and measuring trace flavour and aroma impact materials. Robin was formerly from ICI with a number of years of flavour and aroma analysis experience on their attempts to capture trace components in vivo and in vitro, from natural products from all around the world.

Geoff Kite

Kew Gardens, London

Challenges in natural product characterisation, since one of the aims at Kew is to produce a data bank of all natural products in terms of their characteristic (and unique) chemical composition. He will illustrate his talk with his work on flavonoid analysis by LC and LCMS and the difficulties around correctly identifying these species which often predominate in plant extracts.

Towards the confident identification of simple flavonol O-glycosides by liquid chromatography – mass spectrometry

Dr Geoffrey Kite, Jodrell Laboratory, Royal Botanic Gardens, Kew, Richmond, Surrey TW9 3AB

Flavonoid glycosides are among the most frequently observed components in analyses of aqueous alcoholic extracts of plants by liquid chromatography (LC). They are also the most studied in terms of on-line characterisation by UV spectrophotometry (UV) and serial mass spectrometry (MSn). However, numerous isomeric forms are possible even for relatively simple flavonoid glycosides, and this fact is often overlooked, or assumptions are made, in some studies that ‘identify’ flavonoid glycosides by LC-UV-MSn without reference to authentic standards. Such ‘identifications’ are more correctly expressed as ‘annotations’ of the most likely candidate flavonoid glycoside. Achieving confident identification of simple flavonoid glycosides in the absence of standards remains a challenge. The complexity of the flavonoid glycoside metabolome will be illustrated by examples from legumes containing several isomeric flavonol O-glycosides, and the need for high resolution chromatography to separate isomers will be emphasised. The use of such multi-isomer extracts as tools to improve the confidence in identifying simple flavonol O-glycosides will then be discussed with particular emphasis on recent developments in using MSn of the commonly observed sodiated adduct to discriminate certain disaccharide moieties of flavonol O-disaccharides .

Syngenta’s scientific staff are also supporting the meeting with the following presentations from three of their scientists:

Phil Clarke  

How U is Your UHPLC?

UHPLC has been commercially available for around 10 years but understanding for successful operation of the technique is still growing.  Critical operational parameters will be discussed and the effect of these on the performance of separations will be demonstrated.  Translation of methodology from HPLC to UHPLC and the use of the new generation of sub two micron solid core particles will be used to illustrate some of the challenges that still exist for both instrument manufacturers and practitioners of the technique.

Brian Kemp

Isolating the Needle in the Haystack

The isolation and characterisation of low level impurities is required to comply with the regulations for the registration of pesticides, and also to maintain supplies for use as reference standards in GLP studies. A variety of techniques are used to obtain material containing enriched amounts of these impurities, with the final steps being preparative chromatography

Maximising the Separation and Quantitation of complex food related mixtures using GCMS

Comprehensive GC, GCxGC or “GCSquared” are all terms used to describe a separation system in GC which uses two columns in series containing orthogonal stationary phases. At the point where the two columns join there is located a “Modulator” which repeatedly traps and releases components eluting from the first column onto the second column. The total peak capacity of the system is the product of the two individual peak capacities of the columns. In practise this technique often achieves a component separation increase of a factor of 5 or more. MS is the method of choice when it comes to qualitative and quantitative analysis of these components. This presentation looks at the challenges faced by GCMS in dealing with Comprehensive GCMS data and how a modern Quadrupole analyser excels at this.
