The fruit have glauanol, hentriacontane, [beta] sitosterol, tiglic
acid, [beta]-sitosterol, cycloartenol, cycloeuphordenol, euphol, euphorbinol, isoeuphorbol, palmitic acid, and so forth .
(35) The structures were new and unusual to be comprised of zero or one acetic acid, two or one tiglic
acid(s) and a fatty acid.
To prepare ester derivative 13 and 14, emodin (1) was reacted with tiglic
acid in presence of triethylamine at 0 [degrees]C and acetic anhydride in presence of pyridine respectively (Fig.
slevini is a mixture of methacrylic acid, tiglic
acid, octanoic acid and hydrocarbons, whereas, that of T.
Photooxidations of angelic acid salt (1), tiglic
acid salt (2), 2,3-dimethyl-2-butenoic acid salt (3), and 3-ethoxycarbonyl-5,6-dihydro-2-methyl-4H-pyrane acid salt (4) were conducted in deuterated water ([D.sub.2]O).
