Seven years of research, sometimes in less than hospitable locations around the globe, lie behind Dr Chris Clennett’s new book - The Genus Erythronium: A Botanical Magazine Monograph. By day Chris works in the beautiful botanic gardens of Wakehurst Place at Ardingly, but to write the learned tome on Erythronium he had to climb remote mountain ranges in California and even follow in the path of grizzly bears.

While working on a project studying the medicinal properties of plants, researchers at Kew noticed unusually large flavonoid glycosides in an extract of Iberis saxatilis (a species of candytuft). The compounds were revealed using analysis by liquid chromatography-mass spectrometry, which can be used to separate the chemicals in a plant extract and determine their molecular masses. The largest had a molecular mass of 1300 Da, making it the seventh largest flavonoid glycoside (excluding anthocyanin pigments) currently reported on databases of natural compounds.

Nectar produced by flowers to attract pollinators often contains deterrent or toxic compounds produced by the plant that are normally associated with herbivore defence. The significance of these nectar toxins is not fully understood, and they may have a negative impact on pollinator behaviour and health.
