Từ khóa: triterpenoid, lá cây nhội, This is the preliminarily chemical investigation made on Vietnamese Bischofia triffoliata (Roxb.) Hook.F.Friedelane triterpenoids were isolated and indentified by spectroscopies as fiedelan-3 -ol, fiedelan -3-yl acetate, friedelan-3-one-21-ol along with a common -sitosterol and ursolic acid from the leaves. The findings showed that the triterpenoids as well as tains (known to be quite abundant) of the plant may be used for pharmacological purposes-treating certain diseaseTác giả: Nguyễn Đinh Nga Trần Thành Đại

Từ khóa: Tác dụng kháng nấm, Methyl Lawson, Cây bông mong tay, Lawsone (2-hydroxy-1, 4-naphthoquinone) and methyl lawsone (2- methoxy-1, 4-naphthoquinone) were synthsized from -naphthol in an overall high yield. Both sythetized compounds showed anti-fungal activities. Methyl lawsone was potential against all tested fungi, microsporum gypseum, Trychophytonn mentagrophytes, malassezia furfur ATCC 44344, Malasswzia furfur M1, candida albicans ATCC 10231 and canadida albican 955 (resistant to ketoconazole and clTác giả: Đinh Thị Thanh Hải Nguyễn Quang Đạt Dương Thị Huyền Châm

Từ khóa: 5-aryliden rhodanin, By the condensation of two aromatic aldehydes (p-nitrobenzadehyde and p-fluorobenzaldehyd) with rhodanine; two corresponding 5-arylidenerhodanine derivatives (1, 2) were obtained. The two copounds (1, 2) underwent Mannich reaction to give eight Mannich base derivatives (3-10). The structures pf synthesized compounds were confimed by UV, IR, 13C-NMR and mass spectroscopy. The results of biological activity screening showed that nine compounds having antibacterial activity again© 2017 Sản phẩm của Trung tâm Thông tin Y tế Quốc gia, Bộ Y tế
