Kanglemeisu A (C_(50)H_(63)O_(19)N·CH_3OH) is the product of an actinomyces species from a soil sample gathered in China. Kanglemeisu A belongs to the triclinic system, space group P_1,unit cell:a=12.760(3), b=10.287(2), c=9.926(2) , α=88.39(2),β=78.64(2), γ=89.14(2). RANTAN direct method is used to solve the structure.The final discrepancy factor is R=0.0689, after atom coordinates and temperature factors have been refined with full matrix least squares.The structure skeleton consists of four parts, the naphthalene nucleus connected to the 5-membered ring, a 17-membered ring connected to C_2, a dimethyl butane diacid extended out from C_(20), β-D-3,4-OO’ methylenedigitoxose passing through an oxygen bridge O_6 and linked to C_(27) of ansa ring.
