Abstract

Insecticidal (Z)-6-Methyl-12-heptadecenoic Acid from the Essential Oil of Ageratum conyzoides -[isolation and structure determination of the unsaturated branched chain fatty acid (I), which shows insecticidal and growth regulatory activity against the desert locust Schistocerca gregaria]. -(PARI, K.; SUBRAHMANYAM, B.; RASTOGI, J.

Ethnopharmacological survey and in vitro evaluation of wound-healing plants used in South-western Nigeria

“…By comparison to the plants described above, the antibacterial activity Ageratum conyzoides L. has well been studied (Pari et al, 2000). The essential oil showed weak activity against Staphylococcus aureus, Staphylococcus epidermidis and was inactive against Escherichia coli (Pari et al, 2000). Our data demonstrates that the leaf extracts also showed some activity against all the tested bacteria.…”

“…The slight variation in the values of MICs (Table 3) obtained from this study and that of Awadh et al (2001) could be explained partly because of different concentrations of plant extracts used and method of plant extraction employed. By comparison to the plants described above, the antibacterial activity Ageratum conyzoides L. has well been studied (Pari et al, 2000). The essential oil showed weak activity against Staphylococcus aureus, Staphylococcus epidermidis and was inactive against Escherichia coli (Pari et al, 2000).…”

Phytochemical constituents and ethnopharmacological properties of Ageratum conyzoides L.

“…Triterpenes including friedelin (Katsuri et al, 1973) and sterols such as β-sitosterol (Horng, Lin, & Chen, 1976) and stigmasterol (Hui & Lee, 1971) have been reported. The most commonly found sterols such as brassicasterol (Wiedenfeld & Roder, 1991) and minor sterols like spinosterol (Vera, 1993) and dihydrobrassicasterol (Pari, Subrahmanyam, Rastogi, Devakumar, & Rao, 2000) have also been reported.…”

Disturbed Survival, Growth and Development of the Desert Locust Schistocerca gregaria by Different Extracts of Azadirachta indica (Meliaceae) and Nigella sativa (Ranunculaceae).

“…preparations, or extracts from other plants on the immature-adult transformation program while others reported no effects or even contradictory effects, depending on the activity of the plant species and the susceptibility of the insect species (Hashem and Youssef, 1991;Jagannadh and Nair, 1992;Khalaf and Hussein, 1997;Shaurub et al, 1998;Ghoneim et al, 2000;Hassan, 2002;Al-Dali et al, 2003). Also, some nymphal-adult intermediates were observed in the orthopteran S. gregaria by an essential oil of A. conyzoides (Pari et al, 2000) and by C. rotendus (El-Sokkary, 2003).…”
