TL;DR: Chemical and mechanical analyses of the latex and of the processed rubber indicate that the enhanced elastic behavior of the rubber relative to the unprocessed latex is due to purification of the polymer component and to an increase in the strength and number of interchain interactions that are induced by organic compounds present in I. alba.
Abstract: Ancient Mesoamerican peoples harvested latex from Castilla elastica, processed it using liquid extracted from Ipomoea alba (a species of morning glory vine), and fashioned rubber balls, hollow rubber figurines, and other rubber artifacts from the resulting material. Chemical and mechanical analyses of the latex and of the processed rubber indicate that the enhanced elastic behavior of the rubber relative to the unprocessed latex is due to purification of the polymer component and to an increase in the strength and number of interchain interactions that are induced by organic compounds present in I. alba. These ancient peoples' control over the properties of latex and processed rubber gave rise to the Mesoamerican ball game, a central ritual element in all ancient Mesoamerican societies.

TL;DR: Two new species of Cunaxidae are described from Ipomoea alba L. (Convolvulaceae) on the edge of an urban forest fragment.
Abstract: Two new species of Cunaxidae, Cunaxoides lajeadensis Wurlitzer Monjaras-Barrera sp. nov. and Lupaeus waldumirus Wurlitzer Monjaras-Barrera sp. nov., are described from Ipomoea alba L. (Convolvulaceae) on the edge of an urban forest fragment.

TL;DR: Six new resin glycosides from moon vine seeds (Ipomoea alba) are described as potential mammalian multidrug-resistance-modifying agents and the potentiation of vinblastine susceptibility in multidrog-resistant human breast carcinoma cells of albinosides 1-6 was evaluated.
Abstract: Multidrug resistance is the expression of one or more efflux pumps, such as P-glycoprotein, and is a major obstacle in cancer therapy. The use of new potent and noncytotoxic efflux pump modulators, coadministered with antineoplastic agents, is an alternative approach for increasing the success rate of therapy regimes with different drug combinations. This report describes the isolation and structure elucidation of six new resin glycosides from moon vine seeds (Ipomoea alba) as potential mammalian multidrug-resistance-modifying agents. Albinosides IV–IX (1–6), along with the known albinosides I–III (7–9), were purified from the CHCl3-soluble extract. Degradative chemical reactions in combination with NMR spectroscopy and mass spectrometry were used for their structural elucidation. Four new glycosidic acids, albinosinic acids D–G (10–13), were released by saponification of natural products 3–6. They were characterized as tetrasaccharides of either convolvulinolic (11S-hydroxytetradecanoic) or jalapinolic (...

TL;DR: In this paper, the isolation and structural determination of a hexahydroindolizine alkaloid from the seeds of Ipomoea alba L. (Moonflowers) was reported.
Abstract: : Recent phytochemical studies have shown that the seeds of several members of the Convolvulaceae family, in particular certain Rivea, Ipomoea, and Argyreia species contain significant amounts of ergoline alkaloids. The isolation and structural determination is reported of a new hexahydroindolizine alkaloid from the seeds of Ipomoea alba L. (Moonflowers), the first time indolizines have been isolated from Ipomoea species. (Author)
