The heartwood of H. tiliaceus is red and fades on exposure to light.Like H. elatus heartwood, which behaves similarly, it contains hibiscones A - D and hibiscoquinones A - D; one sample which was devoid of red pigments contained lapachol while roots (from Brazil) contained gossypol, and mansonones D and F.Hibiscoquinone B can be obtained from hibiscones C and D by autoxidation in alkaline solution, and the formation of other hibiscoquinones can be accounted for by related processes.It is suggested that the hibiscoquinones are derived in vivo from the hibiscones.
