The occurrence of furan derivatives in volatiles oils

Summary

The oil from the leaves ofClausena willdenovii, W. and A., has been found to consist almost entirely of three new bodies belonging to the furan group,α-clausenan C₁₀H₁₂O, di-α-clausenan C₂₀H₂₄O₂ andβ-clausenan C₁₀H₁₄O. The former two have been obtained pure and their physical properties recorded. The addition compounds ofα-clausenan with ferro- and ferricyanic acids H₄Fe(CN)₆·2C₁₀H₁₂O, H₃Fe(CN)₆·2C₁₀H₁₂O which can be employed both for its purification and estimation, have been described. It is suggested that the acetyl derivative ofβ-clausenan can be employed for its estimation.
