Some other anti-complementary acidic pectic arabinogalactans including rhamnogalacturonan core and arabinan have also been isolated from medicinal herbs such as the roots of Angelica acutiloba (AGIIb-1) [24-27], berries of Viscum album (Fig. 2) [29], and the roots of Urtica dioica [51]. Their arabinogalactan parts were also characterized as arabino-p-3,6-galactan. 

Pectic arabinogalactans Stevia rebaudiana leaves (Asteraceae family) HSV-1 in-vitro [97]... 

Pectic arabinogalactans with unusual P-(l—> 6)-linked D-Galp residues were isolated from leaves of Stevia rebaudiana (Asteraceae family). Their snti-Herpes simplex virus type-1 (HSV-1) activity was evaluated on infected Vero cells treated with different concentrations of polysaccharides and incubated for 72 h. Results showed that the crude polysaccharides exhibited antiviral activity against HSV-1 in-vitro [97]. 

The common hemiceUulose components of arborescent plants are listed in Table 3. Xylans, arabinogalactans, and pectic substances are common to all while only traces (if at all) of glucomaimans are found in the cell walls of bamboo. Other polysaccharides are found in trace amounts in wood as well as in bark, growing tissues, and other specialized parts of trees.
