Materials and Methods

Lignans for Life Hydroxymatairesinol (HMR) Lignan was obtained from Amazon.com (Seattle, WA, USA), and 1,4-Dioxane and ethanol were obtained from Sigma Aldrich (St. Louis, MO, USA).

Solutions of 2 HMR Lignan capsules + 20.0 mL of 1,4-Dioxane and 4 HMR Lignan capsules + 40.0 mL of 1,4 Dioxane were prepared. These solutions were filtered and analyzed using an Agilent 1100 Series HPLC with a C18 column (4.16 x 100 mm length and 3.5 μm particle size) at absorbance wavelength of 270 nm and temperature of 28°C using an acetonitrile (ACN) and 0.1% TFA gradient for 30 minutes. The first 15 minutes were run at 100% 0.1% TFA, 15-25 minutes at 100% ACN, and 25-30 minutes at 100% 0.1% TFA.

The solution of 4 HMR Lignan capsules in 40 mL of 1,4-Dioxane was used to fill ten 1.5 mL Eppendorf tubes with 1.0 mL of solution. These Eppendorf tubes were placed in a Savant Speedvac SC110 Concentrator (Holbrook, NY, USA) and spun overnight to remove the solvent. The pelleted solute in each Eppendorf tube was then resolubilized using 1.0 mL of EtOH.

The Lignan concentrate (10 μL) in 1.0 mL of H2O was ran on an Agilent 1100 Series HPLC with a C18 column (4.16 x 100 mm length and 3.5 μm particle size) at absorbance wavelength of 270 nm and temperature of 28°C using an acetonitrile (ACN) and 0.1% TFA gradient for 30 minutes. The first 15 minutes were run at 100% 0.1% TFA, 15-25 minutes at 100% ACN, and 25-30 minutes at 100% 0.1% TFA.

The purification and concentration of HMR Lignans for Life is an accessible way of obtaining these hydroxymatairesinol for experimental use. The relative purity and ease of which this substance was concentrated leaves avenues of utilization in terms of future experiments of lignan oxidation and degradation. The HPLC Chromatogram of the concentrated HMR Lignans for Life sample indicates that this material is able to be concentrated and can be used in future experiments.
