抄録

Following isolation of the quaternary base, magnoflorine, and aristolochic acid from the root of Aristolochia debilis SIEB. et ZUCC., examinations were made with larger amount of the plant material and two kinds of acid substance and one neutral substance were newly isolated. These substances were found to be identical with the aristolochic acid-B and -C, and aristololactam (I), isolated from Tao-Fang-chi and reported in the preceding paper.
Components of the crude drug sold on Formosan market as Fang-chi were examined. Its outward appearance was quite similar to Tao-Fang-chi and the components were also similar, isolating magnoflorine, aristolochic acid, aristolochic acid-B and -C, and aristololactam (I). It was thereby found that this crude drug is a root of the plant of Aristolochiaceae family and the same or closely related to that of Tao-Fang-chi.
