“…5-and 7-Hydroxycalamenene (1 and 2) have already been isolated from B. trilobata (Nagashima et al, 1996). Both compounds gave large areas of inhibition zones when bioassayed against C. cucumerinum on TLC plates.…”

Two new tetrahydrofuran lignans, kadlongirins A and B (1, 2), a new cadinane-type sesquiterpenoid, 2,7-dihydroxy-11,12-dehydrocalamenene (3), together with seven known lignans, grandisin, fragransin B 1 , vladirol F, kadsuralignan C, otobaphenol, isoanwulignan, and 4-[4-(3,4-dimethoxyphenyl)-2,3-dimethylbutyl]-2-methoxyphenol, were isolated from the leaves and stems of Kadsura longipedunculata. The structures of these new compounds were elucidated by spectroscopic methods. Compound 2 exhibited weak anti-human immunodeficiency virus-1 activity with an EC 50 value of 16.0 m mg/ml, and therapeutic index (TI) value of 6.7.

“…Moreover, the phytotoxic effect shown in the inhibition of plant seedlings (wheat coleoptile assay) may explain the observation that there is essentially no plant growth under M. grandiflora trees. Cyclocolorenone is also found in Ledum species (Belousova et al, 1989) and in liverworts such as Bazzania trilobata (Nagashima et al, 1996). Both Ledum and Bazzania can build up monocultures in their habitat.…”

In Asia and North America, members of the family Magnoliaceae have been and are presently used extensively in indigenous herbal medicine. Many taxa of the genus Magnolia produce lignans and sesquiterpene lactones, some with considerable in vitro bioactivities. This review focuses on selected natural products of the genus Magnolia from the southeastern United States with demonstrated biological and pharmacological properties. Ethnomedicinal data obtained from the Native Americans of the southeastern United States correlate well with the results of pharmacological investigations.
