The roots agree in structure with those of D elliptica Benth. and probably belong to that sp. The root of D elliptic, a is known as Tuba root from the Malayan name. The root which has strongly toxic properties, has been used as a fish poison in Malaya and elsewhere, and also as an insecticide. Details are given by Wray, Pharm Journal 3 ser. volume 23, p 61 (1892) The p, oisonous principle derrid (or tubain of Wray) is stated to have the chemical formula C33 H30 O10, and to be present in the root to the amount of 2.5 to 3 per cent. For the results of chemical investigation, papers by van Sillevoldt and Greshoff should b, e consulted, viz. Sillevoldt Arch. Pharm. 1899 vol 237 p 595. and Greshoff, Ber Pharm Ges. 1899 vol 9 p 214. as well as the earlier publications Greshoff Ber Chem Ges 1890, vol 23, p 3538, and Wray, Pharm Journ loc cit.
