Objective:To study the antibacterial and antiamylase properties of methanol and acetone extracts of nudibranchs including Bursatella leachii(B.leachii),Kalinga ornata(K.ornata),Aplysia sp.Methods:Crude methanol and acetone extracts of sea slugs were tested for inhibition of fish bacterial pathogens'growth through disc diffusion method.The activity was measured based on the formation of inhibition zone around the disc impregnated with crude extracts.Theα-amylase inhibitory effect was also measured calorimetrically.The chemical fingerprinting of the extract was recorded with HPTLC and GC-MS.Results:The solvent extracts of all the three sea slugs showed antibacterial property.The maximum zone of inhibition(>15-20 mm)was recorded for methanol and acetone extracts of K.ornata.The methanol extract of Aplysia sp.exhibited 93%inhibition againstα-amylase,following by B.leachii(methanol)70.6%and K.ornata(methanol)49.03%inhibition respectively.The acetone extracts didn't show any notable inhibition.The presence of free amino acids like lysine,aspartic acid,glutamic acid,arginine etc.,terpenoids and pigents were confirmed through HPTLC analysis.The presence of siloxanes and propanoic acid were also revealed through GC-MS.Conclusions:This study suggests that further scrutinisation of the B.leachii,K.ornata and Aplysia sp.will pave the way for development of antibacterial andα-amylase inhibitory agent for therapeutic application. 展开更多
