Lonicera morrowii

Thirty-three known iridoid and secoiridoid glucosides have been analysed by gas chromatography of their trimethylsilyl derivatives. G.c.-m.s. analysis of several representative compounds e.g. 4-CO2H, 4-C02Me, 4-unsubstituted) demonstrated the feasibility of iridoid-containing plant extract analysis and resulted in the identification of secologanoside 11-methyl ester (99 R = H, X = CH2) from Lonicera morrowii the sixth paper in a series of chemotaxonomic studies on iridoids illustrates the need for accurate analysis of minor components. ...

Further work on secoiridoid biosynthesis has now shown, using [7,8- H2]-7-deoxyloganic acid, that the C-8 proton as well as the C-7 proton is retained in the sequence loganin secologanin (126)— morroniside (129) (cf. Vol. 3, p. 28) in Lonicera morrowii, Cornus officinalis, and Gentiana thunbergii ... [Pg.28]
