Standards of rutin

Manufactured by Merck Group

Standards of rutin are reference materials used to calibrate and validate analytical methods for the measurement of rutin content in various samples. Rutin is a flavonoid compound that is commonly found in plant-based materials. These standards provide a consistent and reliable means of quantifying rutin levels across different analytical platforms and laboratories.

Rutin and ent-Phyllanthidine Quantification

Check if the same lab product or an alternative is used in the 5 most similar protocols
Standards of rutin and ent-phyllanthidine were obtained from Sigma-Aldrich. Reagents and solvents of analytical grade were purchased from Fluka Chemicals (Busch, Switzerland) and Acros Organics (Hamilton, NJ), respectively. Pre-coated reverse phase HPTLC glass plates of silica gel 60 RP-18F254 were purchased (E. Merck, Germany). The standard and the extracts were applied to RP-HPTLC plates band wise with the help of CAMAG automatic TLC sampler-4 and developed in automatic development chamber-II. Scanning and documentation of developed RP-HPLTLC plate were done by CATS 4 and CAMAG TLC Reprostar 3, respectively.

HPLC Analysis of Bioactive Compounds

Check if the same lab product or an alternative is used in the 5 most similar protocols
Dichloromethane, ethyl acetate, methanol, propan-2-ol and acetonitrile of HPLC-grade were purchased from Fisher Chemicals. Water for HPLC analysis was prepared by a Milli-Q system (Millipore) and passed through a 0.22 µm membrane filter. Standards of rutin (≥95%) and naringenin (≥95%) were purchased from Sigma-Aldrich. Curcumin (≥90%) was obtained from Cayman Chemicals, and piperine (≥97%), sodium carboxymethyl cellulose as well as AFB1 (≥98%) from Sigma-Aldrich. Formic acid and trifluoroacetic acid were supplied by Acros Organics.
All analyses were performed with an HPLC 1200 series with degasser, quaternary pump, automatic liquid sampler, thermostatic column compartment and diode array detector (DAD) from Agilent. Different HPLC columns were tested: XBridge C18 (5 µm, 4.6 x 250 mm) and Kinetex EVO C18, (5 µm, 4.6 x 250 mm). Water with 0.1% formic acid, water with 0.01% trifluoracetic acid, methanol and acetonitrile were evaluated as mobile phases.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
