The present invention relates generally to herbal materials and methods for making such materials in medicinally useful and pharmaceutically acceptable forms. Particularly, the present invention relates generally to(goldenseal) materials and methods for making such materials in medicinally useful and pharmaceutically acceptable forms. More particularly, the present invention relates a process which allows the standardization of the product to specified levels of bioactivity in both hydro-alcoholic tinctures and solid extracts in the processing of goldenseal materials to produce extracts which qualify as pharmaceutical grade compositions which are suitable for use in clinical or veterinary settings to treat and/or ameliorate diseases, disorders or conditions.

Standardization of botanical products utilizing biological activity as a marker

The present invention relates generally to herbal materials and methods for making such materials in medicinally useful and pharmaceutically acceptable forms. Particularly, the present invention relates generally to(goldenseal) materials and methods for making such materials in medicinally useful and pharmaceutically acceptable forms. More particularly, the present invention relates a process which allows the precise standardization of at least two marker compounds, berberine and hydrastine, in both hydro-alcoholic tinctures and solid extracts in the processing of goldenseal materials to produce extracts which qualify as pharmaceutical grade compositions which are suitable for use in clinical or veterinary settings to treat and/or ameliorate diseases, disorders or conditions.

Process for extraction and standardization of pharmaceutical quality tinctures and extracts from herbal products

Disclosed are polyester particles adapted to be extrusion blow molded into articles having improved rheological qualities and a process for producing such particles, said particles comprising a polyester having repeat units from about 40 to 100 mol % terephthalic acid, about 80-98 mol % ethylene glycol, about 0.5-10 mol % 1,4-cyclohexanedimethanol, about 3-10 mol % diethylene glycol, and about 0.05-1.0 mol % of a polyfunctional branching agent, the molecular weight gradient from core to surface of said particles satisfying the following parameters:

Branched copolyesters especially suitable for extrusion blow molding

Disclosed are polyester particles adapted to be extrusion blow molded into articles having improved rheological qualities and a process for producing such particles, said particles comprising a polyester having repeat units from about 40 to 100 mol % terephthalic acid, about 80-98 mol % ethylene glycol, about 0.5-10 mol % 1,4-cyclohexanedimethanol, about 3-10 mol % diethylene glycol, and about 0.05-1.0 mol % of a polyfunctional branching agent, the molecular weight gradient from core to surface of said particles satisfying the following parameters: (A) number average less than 5500, (B) weight average less than 35,000, and (C) Z average less than 110,000

Disclosed is a method of providing a thin copolyester coating on paper wherein the coating has good peel strength which comprises extruding a film of copolyester onto paper to form a coated sheet and passing the paper through a nip formed by a pair of cooperating chill and pressure rolls, wherein the copolyester consists essentially of repeat units from terephthalic acid, ethylene glycol, about 1.5-20 mol % of an aliphatic or cycloaliphatic glycol having 2 to 10 carbon atoms, and 0 to about 1.0 mol % of a polyfunctional branching agent. Also disclosed is the coated paper prepared by this method.

Coating paper with copolyester

Disclosed are copolyesters containing residues of terephthalic acid, ethylene, glycol, 1,4-cyclohexanedimethanol and a trifunctional monomer which are useful in manufacturing rigid containers by extrusion blow-molding processes.

Copolyesters and articles extrusion blow-molded therefrom

Disclosed are multilayered sheets or films which have excellent adhesion. The sheets or film comprise a layer of copolyesterether or copolyester bonded to a layer of polyolefin by means of a tie layer of a copolymer of ethylene and at least one other unsaturated monomer.

Multilayered sheets having excellent adhesion

Disclosed are reactive phenolic compounds having the formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are certain substituents. Also disclosed are certain polyesters normally susceptible to oxidative degradation having copolymerized therein at least one residue of one of the phenolic compounds.

Reactive phenolic antioxidants and polyesters reacted therewith

Disclosed are polyesterether bonding compositions comprising repeating units from trans-1,4-cyclohexanedicarboxylic acid, a difunctional sulfomonomer, a polyetherglycol, and 1,4-cyclohexanedimethanol.

Copolyesterether bonding compositions and shaped articles utilizing the

Disclosed is multi-layered sheet material comprising a layer of polyethylene terephthalate and a layer of an elastomeric copolyesterether. This sheet material is useful in packaging applications where resistance to flex cracking is important.
