New acridone alkaloids from Citrus plants

Motoharu Ju-ichi; Yuko Takemura; Junko Kuwahara; Noriko Nagareya; Mitsuo Omura; Ichiro Kajiura; Ichiro Ito; Hiroshi Furukawa

The spectroscopic structure elucidations of five new acridone alkaloids named yukocitrine (1), yukodine (3), Yukodinine (4), grandisine-III (6) and pummeline (7) from some Citrus plants were described


Heterocycles | 1988

New acridone alkaloid and coumarin from Citrus plants

J.-I. Motoharu; H. Kaga; M. Muraguchi; Mami Inoue; Ichiro Kajiura; Mitsuo Omura; Hiroshi Furukawa

A new acridone alkaloid citramine and a new coumarin osthenon were isolated from the root of the hybrid seedlings of Ogonkan X Hyuganatsu and their structures were elucidated on the basis of spectroscopic data


Journal of The Chemical Society-perkin Transactions 1 | 1990

Spectrometric elucidation of acrimarines, the first naturally occurring acridone–coumarin dimers

Hiroshi Furukawa; Chihiro Ito; Toyoko Mizuno; Motoharu Ju-ichi; Mami Inoue; Ichiro Kajiura; Mitsuo Omura

The structures of acrimarine-A (1), -B (2), -C (3), -D (4), -E (5), -F (6), and -G (7), novel acridone alkaloids carrying a coumarin unit, from the root of Citrus funadoko have been elucidated by spectrometric studies using 1H-13C long-range COSY experiments; acrimarine-A (1) and -F (6) have also been synthesized from the corresponding acridones and coumarins.
