  • Six iridoids were isolated from the 70% ethanol extract of Lonicera Caulis (Caprifoliaceae) and their structures were identified as epialyxialactone (1), secologanin dimethyl acetal (2), sweroside (3), loganin (4), loganic acid (5) and demethylsecologanol (6). The chemical structures of these compounds were identified on the basis of spectroscopic methods and comparison with literature values. This is the first report of the iridolactone, epialyxialactone (1), from the Caprifoliaceae plants and loganic acid (5) and demethylsecologanol (6) from Lonicera Caulis.

  • Two species of Leycesteria, L. gracilis (Kurz) Airy Shaw and L. formosa Wall. (Caprifoliaceae), from the Lao Cai and Yen Bai Provinces are reported here as a new generic record for the flora of Vietnam. During floristic surveys of northern Vietnam, L. gracilis and L. Formosa were encountered. A critical morphological study of all the collected specimens and the type of materials consulting the relevant literature led us to confirm the identity of our collected specimens as L. gracilis and L. formosa. The genus differs from other Vietnamese genera of Caprifoliaceae by the presence of a spike inflorescence or flowers in sessile whorls of 6. Taxonomic notes, description, and photographs are provided, together with short notes on the distribution, ecology and phenology of the two species.

  • Crude drug 'InDong(忍冬)' has been used mainly to cure common cold, high fever and gonorrhea. With regard to the botanical origin of InDong, it has been considered to be Lonicera species of Caprifoliaceae, but there was no pharmacognostical conformation on it. To clarify the botanical origin of 'InDong', the anatomical characteristics of the branches of Lonicera species growing wild in Korea, Lonicera japonica and L. japonica forma. chinensis were studied. As a result, it was clarified that InDong was the branches of Lonicera japonica.

  • Korean folk medicine 'Jeob Gol Mog' has been used to cure nephritis, hypoacidity rheumatis, gastrectasis, and fracture of bone. With regard to the botanical origin of 'Jeob Gol Mog', it has been considered to be Sambucus species of Caprifoliaceae, but there has no pharmacognostical confirmation on it. Morphological and anatomical examination of Sambucus stem show that 'Jeob Gol Mog' was the stem of Sambucus sieboldiana var. miquelii and S. williamsii var. coreana.

  • Two flavonoids, diosmetin 7-0-glucoside and lonicerin, and an iridoid, vogeloside have been isolated from the aerial parts of Lonicera japonica(Caprifoliaceae). The structures of these isolates have been determined by chemical transformations and interpretation of the spectral data. This is the first report of the isolation of diosmetin 7-O-glucoside from this plant.

  • A new 2,7'-cyclolignan named lonicerinol (1) along with eight known lignans, (-)-epipinoresinol (2), (-)-pinoresinol (3), $9{\alpha}$-hydroxypinoresinol (4), 7R,8S-dihydrodehydrodiconiferyl alcohol (5), ($\pm$)-neo-olivil (6), (+)-isolariciresinol (7), 3-methoxy-8,4'-oxyneoligna-3',4,7,9,9'-pentol (8), and (-)-pinoresinol 4-O-glucoside (9), were isolated from the caulis of Lonicera japonica THUNB. (Caprifoliaceae). All of these constituents except for (-)-pinoresinol (3) and $9{\alpha}$-hydroxypinoresinol (4) are reported for the first time from the genus Lonicera. The structures and absolute configurations of these compounds were determined on the basis of spectroscopic analysis, including CD and 1D- and 2D-NMR techniques and chemical methods.

  • From the polar fractions of a 70% EtOH extract of the flower buds of Lonicera japonica (Caprifoliaceae), ten constituents were isolated and identified as iridoid glycosides 7-dehydrologanin (7-ketologanin, 2), secologanin dimethyl acetal (3), (E)-aldosecologanin (centauroside, 5), dimethyl secologanoside (6), secoxyloganin (7) and epivogeloside (8). Other identified constituents were 1-O-$\beta$-D-glucopyranosyl-(2S,3S,4R,8E/Z)-2-[(2R)-2-hydroxy(docosanoyl, tricosanoyl, tetracosanoyl, pentacosanoyl)amino]-8-octadecene-1,3,4-triol (1), uracil (4), D-mannitol (9), and sucrose (10). Among them, 1, 2, 4, and 10 were isolated for the first time from this plant.

  • Fourteen compounds were isolated from the 70% ethanol extract of Lonicera Caulis (Caprifoliaceae) and their structures were identified as seven aliphatic compounds [long-chain alcohols (1, 2), trilinolein (3), hexacosanol (4), fatty acids (6), 9,12,13-trihydroxyoctadeca-10(E),15(Z)-dienoic acid (10), and pinellic acid (11)] and seven phenolics [bis(2-ethylhexyl) phthalate (dioctylphthalate, DOP) (5), coniferaldehyde (7), caffeic acid docosanoyl ester (8), caffeic acid (9), coniferyl aldehyde 4-O-glucoside (12), linarin (13), and coniferin (14)]. The chemical structures of these compounds were identified on the basis of spectroscopic methods and comparison with literature values. All the compounds except for caffeic acid (9) were isolated from this plant parts for the first time.
