Coniferin (= Abietin Coniferoside Coniferyl alcohol 4-0-glucoside Laricin) (phenylpropanoid glycoside)... 

Coniferin (20) is one of the most abundant lignan glycosides occurring mostly in coniferous trees and some other plants. It is the dominant transport and storage form of coniferyl alcohol, which in turn constitutes the main building block of lignins. 

Other phenol glycosides are derived from benzoic acids (Section 6.2.1), like corilagine, or cinnamic acids (Section 6.2.1), like coniferine (Figure 3.15). 

Lignin is a highly polymeric compound. Its structure is not known exactly. It arises from coniferyl alcohol, which has been isolated from wood in its glycosidic form, coniferin. By dehydration and polymerization, coniferyl alcohol is converted to a multiply cross-linked structure. The accompanying figure shows a segment of the molecule with several typical cross links. The molecular weight lies around 10,000. 

Coniferin is a glycoside (a derivative of a sugar) found in conifers, such as fir trees. When a 1.205 g sample of...
