A few of our services are listed below. If you don’t see what you need, contact us .
Alpha Lipoic Acid
α-Lipoic acid (also known as thioctic acid) has been documented as an enzyme cofactor and an antioxidant.
Services Provided: Identification and Quantification of α-Lipoic acid by HPLC (USP-NF Method).
Beta Glucan Content (Yeast, Fungi and Algae)
1-3)-β-glucans are widely distributed in nature, especially in algae, fungi and yeast, and also in higher plants. Venture Labs offers 1,3:1,6-beta-glucan specific testing as well as quantifying α-glucan in preparations. Contact Us for assays to address your specific needs.

Flavonols
An important source of antioxidant compounds the flavonol glycosides are water-soluble pigments responsible for the yellowish hues of cereal grains, fruits and vegetables. Among the most prominent flavonol glycosides are Quercetin, Resveratrol, Gallic acid and Ellagic acid.
Services Provided: HPLC analysis of many Flavonol glycosides using USP-NF methods. Contact us for the availability of analysis of specific flavonol compounds.
Glucomannan from Konjac Flour
Konjac flour is a hydrocolloidal polysaccharide from the tubers of Amorphophallus species of plants. It is a glucomannan polysaccharide consisting of β-1,4 linked glucose and mannose with a molar ratio of 1.6(mannose):1.0(glucose). It is commonly used as a diet aid, gelling agent, thickener, and emulsifier.
Services Provided: Food Chemicals Codex microscopic test FCC Gel Test FCC Heat Stable gel test FCC Total carbohydrate (by subtraction) Percent glucose and mannose (by HPLC)
Inulin
Services Provided: USP Method of Analysis
Inulin and oligofructose occur in foods such as chicory, garlic, onion, artichoke, asparagus, and leeks. The associated fructans are fermented by desirable bacteria such as Bifidobacteria. It is thought that a number of health benefits are associated with increased levels of Bifidobacteria including reductions in Clostridia and coliform bacteria and antimutagenic and anticarcinogenic properties (Sparkes et al., 1998; Reddy, 1999).
Methylsulfonylmethane Assay (MSM)
MSM by USP Method
Polyphenolic Compounds
The polyphenolics are important secondary metabolites produced by plants. Pholyphenolics are responsible for the color and flavor of plant materials. Many have been found to have strong antioxidant and anticancer activities.
Services Provided: Total polyphenolic compounds – By Folin-Ciocaltaeu Colorimetry. Contact us for the availability of analysis of specific Polyphenolic compounds.
Rutin Analysis
Rutin by AOAC Official Method 952.28 (spectrophotometric method) or USP-NF USP40–NF35 Page 7005 (HPLC Method)
Vitamin Analysis
Water Soluble: Ascorbic acid (Vitamin C), Cyanocobalamine (B12), Folic acid, Niacinamide, Pantothenic acid, Para-aminobenzoic acid, thiamine.
Fat Soluble: Vitamin A, A acetate, Vitamin D2, D3, Vitamin E, E acetate and Vitamin K.
Services Provided: Quantification by American Association of Cereal Chemists methods, USP, HPLC and AOAC methods.
Volatile Fatty Acids
(Formic, Acetic, Propionic, Butyric, Isobutyric, Valeric, Isovaleric acids)
Services Provided: Quantification by HPLC or Gas Chromatography.
