Two new picrotoxinin-type sesquiterpenes, flakinins A (1) and B (2), and three new dendrobine-type sesquiterpene alkaloids, mubironines A (3), B (4), and C (5), have been isolated from the whole plants of Dendrobium Snowflake 'Red Star' (Orchidaceae). Their stereostructures were elucidated by 2D NMR data and chemical means. (C) 2000 Elsevier Science Ltd. All rights reserved.
