Extraction of Water Soluble Alkaloids from Hunteria Umbellata
This thesis describes the extraction, isolation, purification of water-soluble alkaloids from the seed, leaf and heart bark of the plant Hunteria Umbrellate. Characterization of the alkaloids was achieved via spectroscopic methods. A total of ten carbazole alkaloids were isolated, two from the seeds and four each from the leaves and bark. Those from the seed and one from the leaves are inferred from the data available to be dimeric. Structures are proposed for most of them, but the lack of some essential facilities do not allow for an unambiguous structural assignment.
