Abstract

Pectins are additive compounds serving as gelling agents. Until now, demands for pectins most solely come from imports, whereas it is known that pectins are available from all around. One of major sources of pectin is from the leaves of Nephrolepis biserrata. The purpose of the study is to settle for characteristics and contents of pectin monosaccharide from Nephrolepis biserrata. The leaves of Nephrolepis biserrata were extracted by reflux using 0.5 N sulphuric acid, then precipitated twice along with 95% ethanol and then dried. Characteristics of pectin in Nephrolepis biserrata were based on 1250 g/mol of equivalent weight, 7.07% of methoxyl content, 48.82% of galacturonic acid content, and esterification degree of 84.16%. Pectin of Nephrolepis biserrata leaves is classified as methoxyl-rich pectins. Moderate sugar monosaccharide contents (g/L) of Nephrolepis biserrata leaves were analyzed using high performance liquid chromatography (HPLC), those are 0.277 arabinose, 0.161 ramnose, 0.035 mannose, 0.011 galactose, and 0.002 xylose. Monosaccharide content of pectin in Nephrolepis biserrata leaves is classified as lower class compared to commercially-available citrus monosaccharide pectin.
