Ebenaceae extractives: Ebenaceae extractives. Part V. New diospyrin derivatives from Diospyros montana Roxb. Lillie, Terence J.In this study， 1617-72-7 and 62417-71-4 are also used.; Musgrave, Oliver C.; Skoyles, Douglas (Chem. Dep., Univ. Aberdeen, Aberdeen, Scot.). J. Chem. Soc., Perkin Trans. 1, (20), 2155-61 (English) 1976. CODEN: JCPRB4. DOCUMENT TYPE: Journal CA Section: 26 (Condensed Aromatic Compounds) Section cross-reference(s): 11, 27, 30, 32 Exts. of the wood of Indian D. montana contained diospyrin (I) and 3,5'-O-cyclodiospyrin (II). Exts. of the bark of D. montana afforded 7-methyljuglone, mamegakinon, biramentacenone, (I), isodiospyrin, (II), 8'-hydroxydiospyrin, 3'-chloro-2'-hydroxydiospyrin, the chromenone ester III (R = Et), and the chromenone acid III (R = H). The CHCl3 ext. of D. montana from Thailand contained 2'- and 3'-chlorodiospyrin. The three chlorodiospyrins are formed from diosquinone during the extn. process. The ext. from the D. montana bark contained allobetulin and oxyallobetulin as well as the expected triterpenoids. .
