Identification
Morphology
Pachyelasma tessmannii is a remarkable tree that maintains a robust, self-supporting growth form. This species can reach impressive dimensions in the wild, with a maximum height of approximately 50 meters. However, some specimens are known to extend even further, potentially reaching a peak of 60.96 meters. Such significant stature allows this plant to command a prominent presence within its natural ecosystem.

Biological Activities
Compounds
Conditions
Pachyelasma tessmannii contains novel triterpene saponins known as pachyelasides A-D that exhibit significant molluscicidal activity. These specific compounds were isolated from the methanol extract of the plant's root bark. When tested against the South American snail, Biomphalaria glabratus, the substances demonstrated an LD50 of less than or equal to 8.0 μg/mL. This biological effectiveness highlights the potential of the plant's secondary metabolites in controlling snail populations. Such findings establish a direct chemical link between the species and its ability to act as a molluscicide.
Preparations
Pachyelasma tessmannii is prepared as a methanol extract of the root bark to facilitate the isolation of secondary metabolites. This specific extraction process led to the discovery of four novel triterpene saponins named pachyelasides A-D. These compounds were successfully identified through the use of recycling HPLC and advanced spectroscopic techniques. The resulting methanol extract is particularly significant due to the molluscicidal activity demonstrated by the isolated saponins. Consequently, the preparation of the root bark into a methanol extract serves as a critical step in studying this African medicinal plant.
Parts used
Pachyelasma tessmannii is an African medicinal plant belonging to the Leguminosae family. Recent phytochemical investigations have focused on the extraction of secondary metabolites from its specific tissues. Researchers successfully isolated four novel triterpene saponins, known as pachyelasides A-D, from the methanol extract of the plant's root bark. These bioactive compounds demonstrated significant molluscicidal activity against the South American snail, Biomphalaria glabratus. The identification of these unique structures provides new insights into the chemical potential of this species' root components.
