  • Two 2-phenoxychromones; a rare group of natural products, were isolated from the combined ethylacetate and chloroform fractions of the ethanolic extract of Ononis serrata frossk (Leguminosae) growing in Egypt. Structures were elucidated by chemical, spectroscopic methods as well as single X-ray diffraction analyses. The cytotoxic and antimicrobial effects of the two compounds were examined. It is worth to mention that this is the first report on the isolation of 2-phenoxychromones from the family Leguminosae.

  • A new species, Indigofera grandiflora B. Choi et S. Cho, was described from sourthern Korea. The new species is related to I. kirilowii and I. koreana in the Far East. However, the species differs from these two species in having larger flowers and leaflets and hairiness on leaflets. The new species is also allied to I. decora in southest China and Japan, but clearly distinguished from the latter by its larger flowers, shorter inflorescences, and hairiness on leaflets.

  • A rare flavonol glycoside identified as $eupalitin-3-O-{\beta}-D-glucoside$ (I) was isolated from Tephrosia spinosa (Leguminosae) and its anti-inflammatory activity was evaluated against carrageenin induced paw edema. The compound exhibited significant activity when compared to the standard drug indomethacin.

  • Two unrecorded alien plants, Melilotus officinalis (L.) Lam. and M. indicus (L.) All. (Leguminosae) were found in Korea. M. officinalis is native to Eurasia and widely distributed in agricultural regions throughout the world. M. indicus is native to Mediterranean and Southwestern Europe, and naturalized in temperate regions all over the world. These species are morphologically similar to M. suaveolens (Jeon-dong-ssa-ri). However, M. officinalis is distinguished from M. suaveolens by transverse nerved legumes, definite ovary stalks, and five to eight number of ovules in ovary. M. indicus is also distinguished from M. suaveolens by smaller size of flowers, broadly triangular calyx teeth, globose legumes, and minutely papillose seeds. The local name of M. officinalis and M. indicus were given as "Ju-reum-jeon-dong-ssa-ri" and "Jom-jeon-dong-ssa-ri" based on transverse nerved legumes and overall smaller size than M. suaveolens, respectively. The descriptions on morphological characters and photographs at the habitat of M. officinalis and M. indicus are provided.

  • For the quality control of Cassiae Semen, anthraquinone compound, aurantio-obtusin, was isolated from the MeOH extract of Cassiae Semen (Leguminosae) and identified by the spectroscopic analysis. A quantitative analysis of aurantio-obtusin using HPLC method showed that the average contents of aurantio-obtusin were $0.03{\pm}0.01%$ in 50 samples collected throughout the various regions of Korea.

  • During our research program to find DNA strand-scission agents from higher plants, the MeOH extracts of the stems of Mucuna birdwoodiana Tutcher. (Leguminosae) exhibited the most potent activity with an $IC_{50}$ value of $4.9\;{\mu}g/ml$. Thus, detailed laboratory investigation was performed, and led to the isolation of known compounds, $({\pm})$-catechin (1) and (-)-epicatechin(2) as active principles. Compounds 1 and 2 showed significant activity of DNA strand-scission with $IC_{50}$ values of 10.8 and $7.5\;{\mu}g/ml$, respectively (positive control, bleomycin: $IC_{50}\;3.3\;{\mu}g/ml$.
