Results of analysis about substances group Polysaccharide, fatty acid, Alkaloid in Scaphium macropodum fruits at regions research

Abstract

The content of group Polysaccharide, Fatty acid, Alkaloid in Scaphium
macropodum fruits fluctuates depending on regions and status of them, in
which Polysaccharide and lipid content in the wind -dispersed fruits (fruits
with a boat-shaped wing derived from a dehiscing follicle) is higher than
other samples. Fruits of S.macropodum have 9 types of fatty acids
varying from Hexadecanoic to Octadecatetraenoic acid ( Acid linolennic),
amongst which the content of Octadecadienoic acid (linoleic acid) is the
highest (from 45.23% to 48.21%). Other acids such as Heptadecenoic ;
Heptadecenoic acid; Margaric acid accounted for a very small amount of
fruits (0.07 - 0.5%). Qualitative analysis results determining for alkaloid in
S.macropodum fruits showed that all samples contain non or very low
concentrations of alkaloids. The contents of Fats (n-hexane extract and
methanol (MeOH) vary depending on regions: highest in samples collected
at Tay Nguyen, next to North Central Coast and lowest South Central
Coast. Fat content (n-hexane and methanol (MeOHextract) of samples in
each region also fluctuate and tends to increase or decrease with age and
status of fruits.
