Hydrocarbons and alcohols of Chamesyce canescens

BRIEF COMMUNICATIONS HYDROCARBONS AND ALCOHOLS OF Chamesyce eaneseens A. I . N u r i t d i n o v a , Z . N. N a z i r o v , and A. K. Karimdzhanov UDC 547.219.16 We have investigated the epigeal p a r t of C h a m e s y c e c a n e s c e n s , family Euphorbiaceae, collected in full-flowering period in the Tashkent oblast. The e o m m i n u t e d plant m a t e r i a l was e x t r a c t e d with c h l o r o f o r m . The yield of e x t r a c t i v e s u b s t a n c e s was 5.99%, of which the a c e t o n e - s o l u b l e f r a c t i o n amounted to 4.46% and the insoluble fraction to 1.53%. The a c e t o n e - i n s o l u b l e f r a c t i o n was heated with p e t r o l e u m e t h e r (bp 40-70°C). The fraction soluble in p e t roleum e t h e r was p a s s e d through a column filled with alumina (length of the column 70 cm, d i a m e t e r 3.4 cm). The column was eluted s u c c e s s i v e l y with p e t r o l e u m ether, benzene, diethyl ether, acetone, and m e t h anol. The f i r s t f r a c t i o n (petroleum ether) yielded the h y d r o c a r b o n dotriacontane, C32H66, m p 69-70°C [1, 2]; the benzene f r a c t i o n yielded the h y d r o c a r b o n triacontane, C30H62, with mp 65-66°C [2, 3]; and the subsequent f r a c t i o n s ( d i e t h y l e t h e r ) y i e l d e d dotriacontanol, C32H6~OH, with mp 87-88°C [1], and triacontanol, C30H61OH, with mp 85-86°C [2, 3]. T h e s e s u b s t a n c e s w e r e identified with authentic s a m p l e s by m i x e d melting points, e l e m e n t a r y a n a l y s i s , and IR s p e c t r a . This is the f i r s t t i m e that the h y d r o c a r b o n s and alcohols mentioned have been isolated f r o m the genus Chamesyce. LITERATURE 1. 2. 3. CITED A. S. Sadykov, Kh. I. Isaev, and A. I.
