Hi Cornel, Many plant constituents are soluble in methanol, at least to some extent. What did you plan to recover? Paul.

Hello Cornel,

Plants produce a wide array of secretions known as mucilages or exudates. They are secreted by seeds, roots, leaves and stems to fulfil a variety of functions such as adhesion, protection, nutrient acquisition, and infection. Mucilages are generally polysaccharide-rich and often occur in the form of viscoelastic gels.

You may use quaternary ammonium salts such as CTAB (cetyl trimethyl ammonium bromide) or CPC (cetylpyridinium chloride) that can form coordination compounds with acidic polysaccharides or long chain high-MW polysaccharides. The coordination compound of quaternary ammonium salt-polysaccharide can be generated in the form of precipitate.

For more information on polysaccharides from natural sources you may want to refer to the article attached below.

Best.

Hello Paul, I was nit trying to recover anything. I only wanted to obtain the extract.
