Five new acyclic amides, clausenalansamides C-G (1-5), clausenaline G (6) and (±)-5-(4-methylphenyl)-γ-valerolactone (7) reported from the natural source for the first time, were characterized from the leaves of Clausena lansium. Their structures were established by spectroscopic and spectrometric
Eight new carbazole alkaloids, claulamines C (1), D (2), and E (5) and clausenalines B-F (3, 4, 6-8), four new coumarins, clausemarins A-D (9-12), and 43 known compounds were isolated from the roots of Clausena lansium. The structures of the new compounds were established on the basis of 2D-NMR
BACKGROUND
Clausena lansium (Fool's Curry Leaf) is used for various ethnomedical conditions in some countries, including bronchitis, malaria, viral hepatitis, acute and chronic gastro-intestinal inflammation, and as a spicy substitute of the popular Curry leaf tree (Murraya koenigii).
OBJECTIVE
This
Glycosides, clausenosides A and B, and carbazole alkaloids, clausenaline A, claulamine A, and claulamine B, together with 50 known compounds, were isolated from the stems of Clausena lansium. Their structures were determined by means of spectroscopic methods, including that of CD and 1D/2D NMR
Seven new carbazole alkaloids, claulansines L-R (1-7), and six known analogues (8-13) were isolated from the stems of Clausena lansium. Their structures were elucidated on the basis of spectroscopic analyses, including UV, IR, and NMR experiments (HSQC, HMBC, and NOE experiment). Compound 7 showed
OBJECTIVE
Mast cells play a central role in allergic and chronic inflammation. Extracts from Clausena lansium (Lour.) Skeels (Rutaceae) possess many pharmacological effects including anti-inflammatory, anti-oxidant, anti-cancer, and anti-trichomonal activities. In addition, the leaves and fruit are
