Three new carbazole alkaloids, mukoenigatin (1), bikoeniquinonine (2) and murrayadinal (3), were isolated from the aerial parts of Murraya koenigii, along with mukeonine-B (4). Their molecular structures were determined on the basis of spectral analysis including UV, IR, MS, and 2D NMR spectroscopy. The antimicrobial activity of different fractions of plant extract was also determined.
从印度楝的地上部分分离出三种新的咔唑生物碱，即穆科尼加汀（1）、比科尼喹宁（2）和默雷亚迪纳尔（3），以及穆科宁 - B（4）。它们的分子结构是基于包括紫外、红外、质谱和二维核磁共振光谱在内的光谱分析确定的。还测定了植物提取物不同馏分的抗菌活性。
