Abstract

Cellulose is the most abundant polymer on earth consisting of ?-l, 4 glycoside rings bound to ?-D-glucose. Cellulose can be obtained from various wood and non-wood sources. Nanocellulose is one of the cellulose derivatives that have the potential to be developed as a carrier agent for natural materials to increase their bioactivity and bioavailability. Nanocellulose, which is cellulose with a nano-size (1-100 nanometer), has been proved as one of the functional material sources that have superior properties due to its attractive and excellent characteristics such as high aspect ratio, better mechanical properties, biocompatibility renewable, and abundance. This paper discusses the sources, production methods, and applications of nano cellulose as a slow-release agent for various natural materials to an applications of biomedical, cosmetic, and biotechnology.

Abstract

Nothaphoebe coriacea (in Kalimantan, Indonesia, commonly known as gemor) is a native wetland-plants that can grow well in swampy areas. This tree is distributed throughout South and Central Kalimantan, Indonesia. The bark of Nothaphoebe coriacea is used for bioactive compound source for larvacide, mosquito repellent, hio and glue. The objective of this research was to investigate the ultrasound-assisted extraction methods for the extraction of antioxidants compounds of Nothaphoebe coriacea. The barks were subjected to ultrasound‐assisted ethanolic and hexane extraction followed by fractionation (using ethyl acetate, chloroform, and hexane) and the antioxidant activity test was performed. The activity of antioxidant was carried out through a DPPH method. The highest antioxidant activities are shown in ethanol extract with IC50 value of 72.36 μg/mL and chloroform fraction of ethanol extract with IC50 value of 54.18 μg/mL.
