['To study the chemical constituents from pine needles of Cedrus deodara.', 'Chemical constituents were isolated by silica gel and Sephadex LH-20 column chromatography. The structures of the isolated compounds were elucidated through spectroscopic analysis.', 'The compounds were identified as 9-hydroxy-dodecanoic acid (I), ethyl laurate (II), ethyl stearate (III), 3beta-hydroxy-oleanolic acid methyl ester (IV), beta-sitosterol (V), shikimic acid (VI), methylconiferin (VII), ferulic acid beta-glucoside (VIII).'] Do [ Study on the chemical constituents from pine needles of Cedrus deodara ]?
