Triterpenoids from Betula costata leaves

Triterpenoids from Betula costata leaves. Uvarova, N. I.; Malinosvskaya, G.In this study， 6892-79-1 and 62023-93-2 are also used. V.; El'kin, Yu. N.; Isakov, V. V.; Dzizenko, A. K.; El'yakov, G. B. (Tikhookean. Inst. Bioorg. Khim., Vladivostok, USSR). Khim. Prir. Soedin., (6), 757-62 (Russian) 1976. CODEN: KPSUAR. DOCUMENT TYPE: Journal CA Section: 11 (Plant Biochemistry) From the unsaponifiable portion of the ether ext. of the leaves of B. costata 4 dammar-like triterpenoids were sepd. For the 2 previously unknown compds. in this group, the following structures were proposed: dammar-24-ene-3.alpha.,17.alpha.,20-triol (I) and betulafolienetetraol oxide (II), resp. The other 2 compds. were identified as betulafolienetriol and betulafolienetetraol. .

Some new triterpenoids from leaves of Betula costata Trautv

Some new triterpenoids from leaves of Betula costata Trautv. Uvarova, N. I.; Malinovskaya, G. V.; Elyakov, G. B. (Pacific Inst. Bioorg. Chem., Far East Sci. Cent., Vladivostock, USSR). 62023-93-2 and 6892-79-1 are cas registry numbers of chemicals which are used as reagents here. Tetrahedron Lett., (50), 4617-20 (English) 1976. CODEN: TELEAY. DOCUMENT TYPE: Journal CA Section: 30 (Terpenoids) Section cross-reference(s): 11 The structures of the triterpenoids I (R = H, R1 = OH) and II, isolated from the leaves of B. costata, were detd. from spectral and chem data. Betulafolienetriol (I; R = OH, R1 = H) and betulafolienetetraol (I; R = R1 = OH) were also isolated. .
