Several derivatives of benzyl 4- Accepted 15 October 2016 O-lauroyl-α-L-rhamnopyranoside were prepared and assessed in vitro for their antimicrobial Available online 15 October 2016 activity against ten human pathogenic bacteria and seven fungi. The structure activity relationship SAR study revealed that incorporation of 4-O-lauroyl group in Keywords Benzyl α-L-rhamnopyranoside rhamnopyranoside frame work along with 2 3-di-O-acyl group increased the antifungal Lauroylation potentiality of the rhamnopyranosides.
