Molecular Structure of Tutin

TUTIN (C15H18O6) was first isolated by Easterfield and Aston1 and identified as the convulsive poison present in the leaves and seeds of the New Zealand species of Coriaria, a shrub known by the Maori as ‘toi toi’. The molecular structure of tutin is now inferred from an X-ray crystal structure analysis of α-bromo-iso-tutin.
