Mirabijalones S-W, rotenoids from rhizomes of white Mirabilis jalapa Linn. and their cell proliferative studies

Phytochemistry Letters, 2021
Five undescribed (2-6) rotenoid derivatives along with three known rotenoids (1, 7 and 8) were isolated from the rhizomes of white colored variety of Mirabilis jalapa Linn. The structures of these undescribed compounds were elucidated based on UV, IR, HR-

Rotenoids from roots of Clitoria Fairchildiana

Phytochemistry, 1998
A new rotenoid, named 9-demethylclitoriacetal, together with the known compounds, 11-deoxyclitoriacetal, 6-deoxyclitoriacetal, clitoriacetal and stemonal, was isolated from roots of Clitoria fairchildiana. Its structure was elucidated as 6a,12a-dihydro-6,9,11,12a-tetrahydroxy-2,3-dimethoxy-[1]benzopyrano[3,4-b] [1]benzopyran-12(6H)-one (1), on the ...

NMR investigations of rotenoids

Tetrahedron, 1973
Abstract Extensive NMR studies of major rotenoids have (1) verified the cis B/C ring fusion of rotenone; (2) confirmed the structure of the reduction-dehydration product of rotenone; (3) provided considerable evidence regarding the preferred conformations of rotenoids; (4) revealed an array of long-range couplings; and (5) pointed up analytically ...

Optical resolution of rotenoids

Journal of Heterocyclic Chemistry, 1987
AbstractOptical resolution of selected rotenoids containing 1‐3 asymmetric centers in dihydrobenzopyranofuroben‐zopyranone and dihydrobisbenzopyranopyranone series has been achieved on two chiral high‐performance liquid chromatographic (hplc) stationary phases.

Novel N-containing rotenoid and seco-rotenoid from the root of Derris elliptica

Journal of Asian Natural Products Research, 2009
Two new rotenoids, 2-hydroxy-5-aminorotenonone (1) and elliptoic acid (2), were isolated from the roots of Derris elliptica collected in Guangdong Province, China. Their structures were established by extensive spectral analysis. Compound 1 is the first N-containing rotenoid and compound 2 is the third rotenoid with the cleavage of C(12)-C(12a).
