- 論文の詳細を見る
Two novel ellagitannin trimers, hirtellins T_2 (1) and T_3 (25), besides previously reported hirtellin T_1 (28), have been isolated from the leaves of Reaumuria hirtella JAUB. et SP. (Tamaricaceae). Hirtellin T_2 has a 36-membered macro-ring structure (1) with three dehydrodigalloyl (m-GOG) units connecting monomers, while hirtellin T_3 (25) possesses one m-GOG and one hellinoyl (m-GO-m-GOG) unit forming a rigid macro-ring, as found in hirtellin B. Two new tannins, tamarixinins T_1 (26) and T_2 (T_<2a>+T_<2b>) (27), having a m-GOG and/or isodehydrodigalloyl (p-GOG) unit were also isolated from the flowers of Tamarix pakistanica QUAISER. The structures these new ellagitannin trimers were elucidated based on chemical methods and spectroscopic analyses, including two-dimensional nuclear magnetic resonance measurements.
