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 guaian type sesquiterpene, torilin, was isolated from the hexane extract of the fruits of Torilis japonica. The $^1H{\;}and{\;}^{13}C-sinals$ of this compound have been fully assigned utilizing $^1H-^1H$ COSY, HMQC, and HMBC experiments.

A new formulation of the MNDIF method is introduced to extract highly accurate natural frequencies of concave plates with arbitrary shape. Originally, the MNDIF method cannot yield accurate natural frequencies for concave plates. To overcome this weak point, a new approach of dividing a concave plate into two convex domains is proposed and the validity and accuracy is shown in a verification example.

Whole plant of Cirsium Pendulum $F_{ISCH}$ was extracted with methanol and a flavonoid glycoside was isolated from the methanol extract. The glycoflavonoid was identified as cirsimarin, $4',5-dihydroxy-6,7-dimethoxyflavone-4'-{\beta}-D-glucopyranoside$.

Nine compounds were isolated from the methanol extract of the aerial parts of Cirsium nipponicum. Their structures were identified to be phytene-1,2-diol (1), ${\beta}-sitosterol$ (2), pectolinarigenin (3), epilupeol acetate (4), 9,12-octadecadienoic acid (5), pinoresinol (6), apigenin (7), linaroside (8) and siparunoside (9) by spectroscopic means.

Ether-soluble flavonoid and neutral fraction (Fr. C) prepared from EtOAc extract of Scutellariae Radix showed inhibitory activities against bradykinin (BK) ; inhibited BK-induced ileum or uterus contractions, antagonized BK-induced plasma extravasation and protected mice from endotoxic shock, reduced acetic acid-induced writhing in mice.

Methanol extract of Ilex pubescens roots prolonged bleeding time threefold, and inhibited the generation of malondialdehyde released during platelet aggregation inducted by thrombin. Through several purification procedures, its saponin, named ilexoside, was proved to be responsible for the antithrombotic activities of the plant. Ilexosides A, -D and -J and 24-carboxypomolic acid showed strong inhibitory activities on platelet aggregation induced by thrombin.

The aqueous ethanolic leaf extract of Ailanthus altissima was found to contain the new natural product, $luteolin\;7-O-{\beta}-(6"-galloylglucopyranoside)$, 13, along with fourteen known phenolic metabolites (1-12, 14 and 15). Structures of all compounds (1-15) were established by conventional methods of analysis and confirmed by FAB-MS, $^1H-\;and\;^{13}C-NMR$ spectral analysis.
