Evaluation of the colchicine-like activity of Gloriosa superba-extracted fractions for mosquito (Diptera: Culicidae) cytogenetic study

Four fractions of Gloriosa superba L., i.e., hexane fraction, dichloromethane fraction 1, dichloromethane fraction 2, and methanol fraction, were investigated for colchicine-like activity using a mosquito cytogenetic assay. The results revealed that the latter three fractions yielded promisingly hig...

Rongsriyam K. Pitasawat B. Jitpakdi A. Rattanachanpichai E. Junkum A. Tuetun B. Chaiwong P. Four fractions of Gloriosa superba L., i.e., hexane fraction, dichloromethane fraction 1, dichloromethane fraction 2, and methanol fraction, were investigated for colchicine-like activity using a mosquito cytogenetic assay. The results revealed that the latter three fractions yielded promisingly high colchicine-like activity, whereas the hexane fraction yielded very low activity compared with 1% colchicine in a 0.85% sodium chloride solution. The metaphase rates and average number of metaphase chromosomes per positive brain ganglion (range) of Aedes aegypti L. larvae after incubation with 0.25-2% solutions of dichloromethane fraction 1, dichloromethane fraction 2, 0.5-2% solutions of methanol fraction, and 1% colchicine solution were 90-100% and 7 (2-19) to 22 (7-47); 90-100% and 4 (1-11) to 30 (4-73); 95-100% and 11 (1-28) to 17 (2-62); and 100% and 6 (2-11), respectively. The temperature stability tests of the three promising fractions were performed by heating 0.5% working solution at 121°C for 15 min and preparing 0.5% working solution from stock frozen at -20°C for 10 mo. These fractions also yielded satisfactory outcomes of metaphase rates and an average number of metaphase chromosomes per positive brain ganglia compared with 1% colchicine solution. 2014-08-30T02:35:35Z 2014-08-30T02:35:35Z 2004 Article 00222585 15311459 JMENA http://www.scopus.com/inward/record.url?eid=2-s2.0-3342887227&partnerID=40&md5=2f6961789be874cf18909454fe2bd46c http://www.ncbi.nlm.nih.gov/pubmed/15311459 http://cmuir.cmu.ac.th/handle/6653943832/4023 English
