Scientists at Kew Gardens have discovered compounds new to science in ordinary elderflower drinks.

While assessing the authenticity and quality of traded plant extracts during a project on ‘Quality botanical extracts for skin and health products’, funded by EPSRC and Procter & Gamble, Kew scientists were surprised to detect major chemical constituents in a commercial extract of elderflower (inflorescences of Sambucus nigra) that had not been reported in the scientific literature.
Following isolation of the compounds from elder inflorescences collected from Kew Gardens it was established that the compounds were derivatives of spermidines, some of which were new to science. The compounds were located in the pollen and provide useful markers to authenticate elderflower extracts.
The research reveals how new chemical discoveries are still possible not only from common British plants but even from the food and drink we consume, as the new compounds were readily detected in commercial elderflower drinks.
