It is of interest to note that rhyncophylline occurs in two genera, Mitragyna and Ourouparia. Raymond-Hamet suggested in 1936 that rhyncophylline, hanadamine and formosanine are chemically and pharmacologically related to the Mitragyna alkaloids and the first chemical evidence of this is the identification of mitrinermine with rhyncophylline (Barger et al.). Millat has recently expressed doubt of this identification. [Pg.756]

About 120 species of plants classified within the family Rubiaceae are used in traditional medicine of Asia and the Pacific, of which, Mitragyna speciosa has been used throughout Southeast Asia, especially in Thailand and Borneo, as an intoxicant. The leaves are chewed alone or mixed with betel, or else prepared for smoking like opium, and its use is legally prescribed in Thailand. [Pg.95]

The N-oxide of the alkaloid dihydrocorynantheol (21) has also been mentioned as a natural product from the leaves of Mitragyna parvifolia (Roxb.) Korth. however, it was detected only by mass spectroscopy and no further evidence for the structure has been given (31). [Pg.149]

Uncaria rhynchophylla Miq. (57). The N-oxide of hirsutine (58) has been found in Uncaria tomentosa DC. (55), and 3-isopaynanthiene (59) has been isolated from Mitragyna speciosa Korth. (58). [Pg.156]

Epiallo Series. Previously, only speciociliatine (63) was known as a cory-nantheine-type alkaloid having an epiallo skeleton. Two new alkaloids in this series were isolated during the last decade, i.e., epiallocorynantheine (64) from Uncaria attenuata (59) and 3-isocorynantheidine (65) from Mitragyna speciosa Korth. (58).

The indole alkaloids of Mitragyna hirsuta Havil, M.javanica Koord. et Val. var. microphylla Craib, M. speciosa, and Nauclea coadunata are mostly in the corynantheine-heteroyohimbine-yohimbine group. The alkaloids isolated from the leaves of Mitragyna hirsuta have been identified as hirsutine, rhynchophylline, isorhynchophylline, mitraphylline, isomi-... [Pg.25]

Glycosidic indole alkaloids have also been isolated cadambine from the bark of Adina cordifolia Hook. f. (94) and 3a-dihydrocadambine from leaves of Anthocephalus chinensis (Lamk.) A. Rich ex Walp. (95). The /3-carboline alkaloid harman is found in the leaves of both Mitragyna hirsuta (64) and Uncaria canescens Korth. (96). [Pg.32]
