“…In study for investigation of new souces of ergoline alkaloids within the genus Ipomoea, I. purpurea was alkaloid-negative species, although previous reports indicated presence of ergoline alkaloids. Maybe because I. purpurea is often confused with I. tricolor an alkaloid-positive species (Amor-Prats & Harborne, 1993b).…”

Approximately 600-700 species of Ipomoea, Convolvulaceae, are found throughout tropical and subtropical regions of the world. Several of those species have been used as ornamental plants, food, medicines or in religious ritual. The present work reviews the traditional uses, chemistry and biological activities of Ipomoea species and illustrates the potential of the genus as a source of therapeutic agents. These species are used in different parts of the world for the treatment of several diseases, such as, diabetes, hypertension, dysentery, constipation, fatigue, arthritis, rheumatism, hydrocephaly, meningitis, kidney ailments and infl ammations. Some of these species showed antimicrobial, analgesic, spasmolitic, spasmogenic, hypoglycemic, hypotensive, anticoagulant, anti-infl ammatory, psychotomimetic and anticancer activities. Alkaloids, phenolics compounds and glycolipids are the most common biologically active constituents from these plant extracts.

“…Efforts to detect ergot alkaloids in Convolvulaceae can lead to inconsistent results, even in assays of plant species known from previous studies to harbor the chemicals [34, 55]. These inconsistencies may be the consequence of any of a number of factors, including sensitivity of the analytical approach chosen to look for alkaloids, age of the plant seed or conditions under which the seed was stored, age of the plant, which plant structures are examined, and incorrect taxonomic work leading to mistakes in species identification [34, 70]. Alkaloid levels within a single plant may vary with plant structure.…”

Survival and development of potato psyllid (Hemiptera: Triozidae) on Convolvulaceae: effects of a plant-fungus symbiosis (Periglandula)

Plant species in the family Solanaceae are the usual hosts of potato psyllid, Bactericera cockerelli (Šulc) (Hemiptera: Psylloidea: Triozidae). However, the psyllid has also been shown to develop on some species of Convolvulaceae (bindweeds and morning glories). Developmental success on Convolvulaceae is surprising given the rarity of psyllid species worldwide associated with this plant family. We assayed 14 species of Convolvulaceae across four genera (Convolvulus, Calystegia, Ipomoea, Turbina) to identify species that allow development of potato psyllid. Two populations of psyllids were assayed (Texas, Washington). The Texas population overlaps extensively with native Convolvulaceae, whereas Washington State is noticeably lacking in Convolvulaceae. Results of assays were overlain on a phylogenetic analysis of plant species to examine whether Convolvulaceae distantly related to the typical host (potato) were less likely to allow development than species of Convolvulaceae more closely related. Survival was independent of psyllid population and location of the plant species on our phylogenetic tree. We then examined whether presence of a fungal symbiont of Convolvulaceae (Periglandula spp.) affected psyllid survival. These fungi associate with Convolvulaceae and produce a class of mycotoxins (ergot alkaloids) that may confer protection against plant-feeding arthropods. Periglandula was found in 11 of our 14 species, including in two genera (Convolvulus, Calystegia) not previously known to host the symbiont. Of these 11 species, leaf tissues from five contained large quantities of two classes of ergot alkaloids (clavines, amides of lysergic acid) when evaluated by LC-MS/MS. All five species also harbored Periglandula. No ergot alkaloids were detected in species free of the fungal symbiont. Potato psyllid rapidly died on species found to harbor Periglandula and fungus-produced alkaloids, but survived on species in which the mutualism was absent. These results support the hypothesis that a plant-fungus symbiotic relationship affects the suitability of certain Convolvulaceae to potato psyllid.

“…90 Another close relative to the Calystegia and Convolvulus is the Ipomoea genus, the seeds of several varieties of which, particularly Ipomoea violacea, contain the tryptamine lysergic acid amide (LSA), which has psychedelic and hallucinogenic effects when ingested. The ground seeds are known to have been used for divinatory purposes, particularly in Mesoamerica (Hofmann 1963(Hofmann , 1971Amor-Prats and Harborne 1993). A member of the same family, Ipomoea sagitta, grows in Apulia, but there is no evidence for it having been used as an ancient narcotic.…”

Tenacious Tendrils: Replicating Nature in South Italian Vase Painting

Elaborate floral tendrils are one of the most distinctive iconographic features of South Italian vase painting, the red-figure wares produced by Greek settlers in Magna Graecia and Sicily between ca. 440-300 B.C. They were a particular specialty of Apulian artisans and were later adopted by painters living in Paestum and Etruria. This lush vegetation is a stark contrast to the relatively meager interest of Archaic and Classical Athenian vase painters in mimetically depicting elements of the natural world. First appearing in the work of the Iliupersis Painter around 370 B.C., similar flowering vines appear in other contemporary media ranging from gold jewelry to pebble mosaics, perhaps influenced by the career of Pausias of Sicyon, who is credited in ancient sources with developing the art of flower painting. Through analysis of the types of flora depicted and the figures that inhabit these lush vegetal designs, this paper explores the blossoming tendrils on South Italian vases as an evocation of nature's regenerative powers in the eschatological beliefs of peoples, Greek and Italic alike, occupying southern Italy.
