Ipomoea cairica is vining perennial, twining and herbaceous, up to 4 meters long, smooth or muricate. Leaf blades are 3 to 10 centimeters long, palmately divided in 5 to 7 lobes. Flowers are showy, white to lavender, peduncles 5 to 80 millimryrtd long. Corolla is purple, bluish purple or white with a purple center, funnelform, 4.5 to 6 centimters long.

Morning glory2Constituents
– Phytochemical analysis of methanol extracts of leaves and flowers yielded alkaloids, carbohydrates, tannins, phenolic compounds, proteins and amino acids, terpenoids, sterols, and saponins. (see study below)
– Phytochemical screening of various extracts (petroleum ether, CHCl2, Ch3OH) of leaves and flowers yielded alkaloids, sterols, flavonoids, reducing sugars, tannins, saponins, terpenoids, antrhaquinones, glycosides, and phenols.
– An ethanolic extract yielded compounds, 3,5-Di-O-caffeoylquinic acid and 4,5-Di-O-caffeoylquinic acid.
– Study of aerial parts isolated six pentasaccharide resin glycosides, four new acylated ptentasaccharide resin glycosides, namely cairicoside I-IV and two known compounds, cairicoside A and cairicoside C,
– Study of aerial parts isolated the coumarins umbelliferone and scopoletin, and the dibenzyl-γ-butyrolactone lignans arctigenin, matairesinol and trachelogenin, along with β-sitoterol and fatty acids.

– Studies suggest antioxidant, anti-diabetic, antinociceptive, antimicrobial, mosquitocidal properties.

• No reported folkloric medicinal use in the Philippines.
• In Brazilian folk medicine, used for rheumatism and inflammation.

Study Findings
• Larvicidal / Essential Oil: A study of the essential oil for its larvicidal effect against four vector species of mosquitoes showed remarkable larvicidal properties, inducing 100% mortality in the larvae of Culex tritaeniorhynchus, A aegypti, A stephensi and Culex quinquefasciatus.
• Antinociceptive / Essential Oil: Study yielded 3,5-di-O-caffeoylquinic acid and 4,5-di-O-caffeoylquinic acid which have been reported to have analgesic and antioxidative effects. The results show antinociceptive effects probably through release of pro-nociceptive mediators. The isolated caffeoylquinic acids can partly explain the antinociceptive effect of Ipomoea cairica polar extract.
• Antinociceptive / Essential Oil: Study evaluated crude methanolic extract of Ipomoea cairica leaves for residual and persistence effects against Culex quinquiefasciatus larvae. Results showed a short period of residual effectiveness of crude acethonilic extract of leaves with high percentage of larval mortality on the first few days that endorses less concerns of excess environmental residues, insecticide resistance and environmental pollution.
• Biolarvicidal Against Key Dengue Vectors: Study evaluated the efficacy of I. cairica extract against two different mosquito larvae: Ae. albopictus and Ae. aegypti. Results showed remarkable larvicidal properties and suggests exploration of alternatives to chemical larvicides such as Abate, Temephos for mosquito control program.
• Antimicrobial / Antioxidant / Leaves and Flowers: Study investigated methanol extracts of leaves and flowers of I. cairica for antimicrobial and antioxidant effects. Results showed very good activity against all bacterial and fungal strains tested. The extract also showed remarkable antioxidant activity, with DPPH scavenging activities correlating with its reductive potential.
• Antinociceptive / Antioxidant / Leaves and Flowers: Study of Ipomoea cairica extract showed dose dependent reduction of rewsponse in the formalin test inflammatory phase in mice. A possible explanation for the antinociceptive activity is the release of pro-nociceptive mediators unrelated to carrageenan-induced edema. The isolated caffeoylquinic acids could explain, in part, the antinociceptive effect.
• Oviposition Deterring and Oviciding Potential Against Dengue Vectors: Study of Ipomoea cairica demonstrated oviposition deterring and oviciding potentials against dengue vectors, Ae. aegypti and Ae. albopictus. Results suggest a potential alternative source for the development of novel plant based insecticides.
• Pentasaccharide Resin Glycosides / α-Glucosidase Inhibitory Activity / Anti-Diabetic: Study of aerial parts yielded six pentasacchride resin glycosides. Compounds 1-4, four new acylated resin glycosides, cairicoside 1-IV, all showed anti-diabetes or inhibitory activity against α-glucosidase.
• Mosquito-Larvicidal / Dibutyl Phthalate / Stems: Study for larvicidal activities of I. cairica stem extracts, fractions isolated a secondary metabolite,dibutyl phthalate. Findings demonstrated that the crude extracts and pure compound of stem showed potent larvicidal activity against C. quinquefasciatus and A. aegypti.Results suggest an ecofriendly and cost-effective larvicide for mosquito control.
