To study extracts of the cotton biocides it has collected more than thirty species of plants, which were classified taxonomically in the Natural History Museum of the Universidad Nacional Mayor de San Marcos, between species that are considered relevant for its insecticidal properties we have the following species: Tephrosia cinerea (sacha barbasco), Artemisia absinthium (wormwood), Ryania speciosa (riania), Cissampelos grandifolia (legia), Datura stramonium (chamico), Hura crepitans (catahua), Schinus molle (molle), Annona cherimola (chirimoya), Annona muricata (guanabana or graviola), Tagetes patula (Marigold), Tanacetum parthenium (santa maria), Chromolaena laevigata (sacha huaca), Clibadium asperum (huaca), Lonchocarpus nicou (Mount mullein), Lonchocarpus spiciflorus (yumanasa), Centropogon cornutus (arco sacha), Erythrina berteroana (small amasisa), Erythrina edulis (pajuro), Erythr...

Con el fin de sustituir los insecticidas químicos usados en el cultivo del algodonero por sustancias inócuas que permitan un manejo integrado de plagas con fundamento ecológico, se investigaron y colectaron 40 especies vegetales con propiedades biocidas, las que fueron clasificadas taxonómicamente en el Museo de Historia Natural de la Universidad Nacional Mayor de San Marcos. Entre las especies más relevantes por sus propiedades insecticidas tenemos: Tephrosia cinerea (sacha barbasco), Artemisia absinthium (ajenjo), Ryania speciosa (riania), Cissampelos grandifolia (legía), Datura Stramonium (chamico), Hura crepitans (catahua), Schinus molle (molle), Annona cherimola (chirimoya), Annona muricata (guanábana o graviola), Tagetes patula (marigold), Tanacetum parthenium (santa maría), Chromolaena laevigata (sacha huaca), Clibadium asperum (huaca), Lonchocarpus nicou (barbasco del mon...

To give scientific support to the traditional use of plants, was studied the aqueous extract of dried leaves of Annona muricata L. "Soursop", specie collected in the highlands jungle of Cuzco, which was classified taxonomically in the Natural History Museum of the UNMSM; Annona muricata L. revealed the presence of flavonoids and other metabolites. The aqueous extract was classified as non-toxic according to the method of dose limits for the determination of acute toxicity, result supported with the macroscopic study of organs made at the Faculty of Veterinary Medicine UNMSM. By employing the method of plantar edema induced by λ-carrageenan mouse model, the aqueous extract of Annona muricata L., at concentration of 1,5mg/kg, had significant anti-inflammatory efficacy compared to indomethacin. The statistical analysis was carried out by ANOVA at 95% confidence.
