| From the roots the bisbenzylisoquinoline alkaloids 2’-norcocsoline, cocsoline-N-oxide and 12-O-methylcocsoline-N-oxide have been isolated, as well as a number of alkaloids of various structures, including anisocycline, palmatine, liriodenine, remrefidine, 1,2-dehydroapateline, 1,2-dehydrotelobine and trilobine. The bisbenzylisoquinoline alkaloids 2-norobaberine-2’-β-N-oxide, 2-norobaberine, daphnandrine, coclobine, anisocycline, palmatine, and remrefidine have been isolated from seeds. Their role in neurochemistry is being studied. The leaves contain N-O-dimethylthaicanine, N-methylthaicanine, N-methyltetrahydropalmatine, anisocycline, palmatine, and stephenanthrine. | |||

| Dioecious liana; stem up to 5 cm in diameter; bark with circular leaf scars. Leaves arranged spirally, simple and entire; petiole up to 6 cm long, thin, grooved; blade broadly ovate to elliptical, 6–10 cm × 3–6.5 cm, base rounded to slightly cordate, apex acuminate, glabrous, pinnately veined with 3–5 pairs of lateral veins. Inflorescence an axillary, many-flowered cyme, single or paired, 2–8 cm long, reddish hairy. Flowers unisexual, small; pedicel short; sepals 9 in 3 whorls, yellowish hairy, sepals of outer and middle whorls 0.5–1.5 mm long, 3 inner sepals 2–3 mm × 1–1.5 mm; petals broadly ovate, c. 1.5 mm long, narrowing to the base, glabrous; male flowers with 9–18 stamens c. 3 mm long, filaments fused; female flowers with superior ovary composed of 3 free carpels 2–4 mm long, styles cylindrical, glabrous. Fruit composed of 1–3 drupes; stone bony. Anisocycla comprises 6 species, 4 in continental Africa and 2 in Madagascar. Anisocycla grandidieri Baill. is endemic to northern Madagascar, where it occurs below 500 m altitude. A very bitter decoction of its yellow roots is used to cure diseases of the kidneys and the bladder. Sap from the roots is used as a coagulant. The roots contain the bisbenzylisoquinoline alkaloids epistephanine, stebisimine, trilobine and 12’-O-demethyltrilobine. Epistephanine and stebisimine have shown spasmolytic activity in isolated guinea-pig ileum. Anisocycla jollyana (Pierre) Diels is a climbing shrub occurring in fringing forest from Equatorial Guinea to western DR Congo. It does not have recorded medicinal uses, but its chemistry was researched because its close relative Anisocycla cymosa contains many interesting alkaloids. The roots of Anisocycla jollyana contain a great variety of bisbenzylisoquinoline alkaloids and dioxine alkaloids, including cycleanine, limacusine, apateline and isochondrodendrine and its derivatives fastrine and jollyanine. From the leaves the secodibenzylisoquinolines secojollyanine and secohomoaromaline have been isolated, as have several bisbenzylisoquinoline alkaloids. | |||

| Additional research on the phytochemistry and pharmacology of Anisocycla cymosa and the other Anisocycla species seems warranted in view of the uses and the numerous bioactive constituents. | |||
