Abstract:
A new xanthone glycoside, 3,5,7,8-tetramethoxyxanthone-1-O-β-D-glucopyranoside (1), along with five known compounds, mangiferin (2), kaempferol (3), quercetin (4), chlorogenic acid (5) and diploptene (6), was isolated from the whole plants of Pyrrosia sheareri (Bak.) Ching. The structure of compound 1 was established on the basis of extensive spectroscopic analyses and chemical methods.

Carbohydrates are an essential part of the diet in humans and animals. Grains, fruits, and vegetables are natural sources of carbohydrates that provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. The stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule represents carbohydrates. In other words, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. This...

The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...
