Insecticidal and antifungic proteins of the latex from Manihot glaziovii Muell. Arg.

Antinociceptive activity of Calotropis procera latex in mice

“…Latexes are source of various biologically active compounds, including glucosides, tannins and many proteins, among others (Wititsuwannakul et al, 2002;Dubey and Jagannadham, 2003). Characterization of the compounds of Calotropis procera latex supports the hypothesis that this natural secretion is involved in plant defense mechanisms (Girdhar et al, 1984;Pereira et al, 1999). Apart of its defensive role, latex components seem to be able to induce interesting biological effects since the plant itself is known by its pharmacological potentialities.…”

Latex constituents from Calotropis procera (R. Br.) display toxicity upon egg hatching and larvae of Aedes aegypti (Linn.)

“…When injured, leaves or the nearest other green parts exude the latex secretion which has a clingy effect capable of immobilizing insects. Additionally, the presence of plant defense-related proteins such as hevein, alpha-amylase inhibitor, among others, has been described to occur in the latex secretion of other plants (Wititsuwannakul et al 1998, Pereira et al 1999) and this seems to be also the case of Calotropis latex (Dubey & Jagannadham 2003). Scien-tific descriptions have mentioned other relevant activities for the latex of C. procera, such as antibacterial, analgesic or possessing in vitro schizonticidal activity, among others (Jain et al 1996, Dewan et al 2000, Sharma & Sharma 2000, Alencar et al 2004.…”
