Extraction of the active principle of Siegesbeckia orientalis

Extraction of the active principle of Siegesbeckia orientalis. (Fabre, Pierre, S. A., Fr.). Fr. Demande FR 2285142 16 Apr 1976, 15 pp. (French). (France). CODEN: FRXXBL. CLASS: IC: A61K031-70. APPLICATION: FR 74-31469 18 Sep 1974. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 11, 62 A method is described for the extn. of the active principle of S. orientalis. Finely pulverized S. orientalis is extd. with an appropriate boiling org solvent. After sepn. of the residue, pigments are removed from the supernatant and darutoside (I) [59219-65-7] is pptd. by the addn. of a strong base. The soln. is neutralilzed and I crystals are removed and neutralized. For example, 1 log of finely ground S. orientalis was initially extd. with 8.5 L, then 5 L of butanol. The exts. were combined and treated with activated charcoal followed by the addn. of 150 mL of NaOH. After filtration and neutralization 12.7 g of I, m.In this experiment, several chemicals are used like 59219-65-7 p. 234.degree., was obtained. .
