“…Several articles had reported on different biological activities of the above species, namely, anti-inflammatory and molluscicidal properties of Agave americana (Shoeb et al, 1984;Peana et al, 1997), molluscicidal activity of Agave lophantha (El-Sayed et al, 1991), anti-inflammatory activity of Calotropis procera (Kumar & Basu, 1994), hypoglycemic activity of Pergularia tomentosa (Shabana et al, 1990), antiviral activity of Alkanna orientalis (El-Sohly et al, 1997), antibacterial, antinociceptive, and antiinflammatory effects of Pimenta racemosa Saenz et al, 2004), antimicrobial activities of Verbascum sinaiticum (Tadeg et al, 2005), molluscicidal properties of Solanum elaeagnifolium (Bekkouche et al, 2000), and molluscicidal and cercaricidal activities of Solanum nigrum (Ahmed & Ramzy, 1997).…”

In vitro bioassay screening of 346 methanol extracts originated from 281 native and cultivated plant species growing in Egypt, and related to 81 families, was carried out for schistosomicidal activity. The extracts were bioassayed at 100 mg=mL on viable Schistosoma mansoni mature worms in culture medium. Viability of worms was examined after exposure for 24 h, and mortality determined. Negative (DMSO) and positive (praziquantel) controls were used. Of the tested plant extracts, 72 were found to possess reproducible in vitro antischistosomal activity. These active extracts were further subjected to determination of their LC 50

“…From the above, different research has found that some Agave species such as A. filifera, A. celsii, A. sisalana, A. decipiens Baker, and A. lophanta exerted molluscicide activity against Biomphalaria alexandrina [75,[89][90][91], a snail vector of Schistosoma mansoni, which causes schistosomiasis. The effective lethal dose and extract type are summarized in Table 3.…”

Hunting Bioactive Molecules from the Agave Genus: An Update on Extraction and Biological Potential

Agaves are plants used in the production of alcoholic beverages and fibers. Ever since ancient times, pre-Hispanic cultures in Mexico have used them in traditional medicine to cure different ailments. Over the years, studies of the active principles responsible for the therapeutic benefits of agaves have increased. Leaves and fibers are the main agro-wastes generated in tequila and mezcal production, while fibers are the main waste product in the textile sector. Different investigations have referred to the agro-waste from agave processing as a source of bioactive molecules called secondary metabolites (SM). Among them, phenols, flavonoids, phytosterols, and saponins have been extracted, identified, and isolated from these plants. The role of these molecules in pest control and the prospect of metabolites with the biological potential to develop novel drugs for chronic and acute diseases represent new opportunities to add value to these agro-wastes. This review aims to update the biological activities and recent applications of the secondary metabolites of the genus Agave.

“…The toxicity and rising costs of synthetic molluscicides have led to interest in compounds derived from locally growing plants that can be used as molluscicides. For example, extracts of Agave attenuata, Agave sislana, Agave igrelliana, Agave lophantha, Phytolaca dodecandra, Euphorbia spllendens and Ambrosisa maritima have been tested as molluscicide activity (De Souza et al, 1987;El-Sayed et al, 1991;Abdel-Hamide, 1997;Mendes et al, 1997;Brackenbury, 1999;Tiwari et al, 2004).…”

The toxicity and rising costs of synthetic molluscicides have led to interest in compounds derived from locally growing plants that can be used as molluscicides. The aim of the present work was to study the effect of extracts of some Egyptian plants having lethal effect on snails of medical importance (Biomphlaria alexandrina) as well as on antioxidant and glutathione detoxification enzymes. Ethanolic extracts of locally growing plants Agave attenuata, Agave sislana, Phytolaca dodecandra and Euphorbia spllendens were applied as a contact poison to B. alexandrina, the intermediate host of Schistosoma mansoni. The LC50 of A. attenuata, A. sislana, P dodecandra and E. spllendens are 82, 101, 98 and 98 mg/L, respectively. Glutathione and the enzymes involved in protection of the snail from reactive oxygen species namely, glutathione peroxidase, glutathione reductase, glutathione S-transferase, catalase, gamma glutamyl transferase increased in the survival snails exposed to high concentrations of A. attenuata. Glucose-6-phosphate dehydrogenase indirectly affecting glutathione reductase and the oxidation, reduction of glutathione significantly decreased in snails exposed to A. attenuata extracts. Superoxide dismutase level tend to decrease in snails exposed to A. attenuata of action. In conclusion A. attenuata is preferable when compared with synthetic molluscicides. The enzymes involved directly or indirectly in protection mechanism of the snail against A. attenuata are mainly responsible for snails survival.
