Two new N-oxide alkaloids from Stemona cochinchinensis.
Two new N-oxide alkaloids with pyrrolo[1,2-α]azepine skeleton, namely isoneostemocochinine-N-oxide (1) and neostemocochinine-N-oxide (2), as well as three known alkaloids with pyrido[1,2-α]azepine skeletons, were isolated and identified from the roots of Stemona cochinchinensis (Stemonaceae). The structures of these compounds were elucidated by 1D- and 2D-NMR spectra and other spectroscopic stu...
متن کاملTwo New Alkaloids from Roots of Stemona tuberosa
The roots of Stemona tuberosa have been used as an antitussive and insecticide remedy for thousands of years. On the chemical investigation of the roots of S. tuberosa, two new tuberostemonine-type alkaloids, epoxy-tuberostemonol (1), and neotuberostemoenone (2), together with a known alkaloid, neotuberostemonine, were isolated and identified. The structures of new alkaloids were established on...
متن کاملPhytochemical studies on Stemona burkillii prain: two new dihydrostemofoline alkaloids.
Two new dihydrostemofoline alkaloids, 11(S),12(R)-dihydrostemofoline (3) and stemoburkilline (4), along with stemofoline (1) and 2'-hydroxystemofoline (2) have been isolated from a root extract of Stemona burkillii Prain. The structure and relative configuration of 3 have been determined via spectroscopic data and from comparison with synthetic 11(S),12(S)-dihydrostemofoline (5). The configurat...
متن کاملTwo new isoquinolone Alkaloids from Sauropus hirsutus
Sauropus androgynus (Euphorbiaceae) is a popular vegetable in Thailand. In 1995, the plant was associated with several cases of poisoning when used in a Taiwanese weight control method and the toxicity was attributed to its alkaloid content. We have therefore investigated a closely related Sauropus species, S. hirsutus. Extraction and isolation of chemical constituents from the aerial part of S...
