Chemical constituents of three Allium species from Romania.
The aim of this work was to study the chemical composition of Allium obliquum L., A. senescens L. subsp. montanum (Fries) Holub, and A. schoenoprasum L. subsp. schoenoprasum. Sulphur-containing compounds analysis was performed by an LC-MS method, the identification and quantification of polyphenolic compounds through a HPLC-UV-MS method, and the presence of five sterols was simultaneously assessed by HPLC-MS-MS. Alliin was identified only in A. obliquum and A. senescens subsp. montanum extracts, whilst allicin was present in all extracts, with higher amounts in A. schoenoprasum and A. obliquum. The pattern of phenol carboxylic acids shows the presence of p-coumaric and ferulic acids in all species. Isoquercitrin was identified in A. obliquum and A. schoenoprasum, and rutin in A. senescens subsp. montanum and A. schoenoprasum. Luteolin and apigenin were identified only in A. obliquum. All three species contain glycosides of kaempferol and quercetol. β-Sitosterol and campesterol were identified in all species. The results obtained showed significant differences in the composition of the three Allium species.

[Studies on chemical constituents from twigs of Morus atropurpurea].
To study the chemical constituents of the twigs of Morus atropurpurea.. The compounds of the EtOAc fraction were isolated and purified by column chromatography on silica gel, polyamide, Sephadex LH -20, and their structures were elucidated on the basis of spectroscopic evidence (MS, NMR).. Eleven compounds were identified as mulberrin (1), cyclomulberrin (2), morusin (3), cyclomorusin (4), 2', 4',4, 2"-tetrahydroxy-3'-{3"-methylbut-3"-enyl-}-chalcone (5), mulberrofran G (6), scopoletin (7), moruchalcone A (8), kaempferol (9), ursolic acid (10), beta-daucosterol (11).. Except compounds 9 and 11, all the other compounds were obtained from M. atropurpurea for the first time.
