Three Stemona alkaloids named stemotuberines A–C (1–3) with unique C 17 N frameworks,
presumably formed by elimination of the C-11–C-15 lactone ring of the stichoneurine …

The structural revision of four Stemona alkaloids from Stemona tuberosa is reported. The
misassignment of the tuberostemonine O structure (1) was recognized when a new alkaloid …

A new stemona alkaloid, tuberostemonone (C 22 H 31 NO 6), has been isolated from the
roots of stemona tuberosa Lour, and its molecular structure determined by MS, IR, NMR …

Four new alkaloids, tuberostemonone [1], tuberostemonol [2], stemoamide [31, and
tuberostemospironine [4], together with two known alkaloids, tuberostemonine and …

Two new alkaloids, named tuberostemoninol A (1) and tuberostemoninol B (2), along with
the known compounds tuberostemoninol (3) and bisdehydroneotuberostemonine (4), were …

Publisher Summary This chapter discusses experimental studies focusing on Stemona
alkaloids. Kaneko extended the early work of Schild on tuberosternonine, demonstrating the …

Six undescribed alkaloids, neotuberostemonol C (1), dehydrostenines CD (2–3),
tuberostemonines QR (10–11), and (6R, 8R, 8aR)-8-hydroxy-6-methyl-hexahydroindolizin-5 …

A new alkaloid, stemona-lactam S, and a known alkaloid, tuberostemospiroline, were
isolated from the roots of Stemona tuberosa LOUR.(Stemonaceae). Their structures and …

Four new alkaloids, didehydrotuberostemonine A (1), stemoninone (2),
tuberostemospiroline (3), and tuberostemonine L (4), together with seven known alkaloids …

The alkaloids tuberostemonine, oxotuberostemonine, and the new base tuberostemonine-A
have been isolated from the rhizomes of Stemona sessilifolia. Tuberostemonine has been …
