Plant Pigment Profiling Service

High-quality Profiling of Plant Pigment at Creative Biolabs

Plant pigments are important nutrients in plants, and their analysis is used to monitor sources of biomass in the environment. Certain plant pigments provide antioxidant substances needed by the human body and are often used as food additives. During food processing, plant pigments can be damaged or lost, so plant pigment analysis can help the food industry ensure the quality and nutritional value of their products. Creative Biolabs has advanced analytical technology and laboratory facilities, and our professional team accurately measures and analyzes the composition and content of plant pigments.

We offer many types of plant pigment profiling services:

• Chlorophyll: Chlorophyll is one of the most common pigments in plants, which includes chlorophyll a and b. Their molecular structures are different, but they can both absorb light. Chlorophyll a has absorption maxima at 372 nm and 642 nm, and chlorophyll b at 392 nm and 626 nm. Chlorophyll a has been used as a natural green colorant in food and formulations.
• Carotenoids: Carotenoids are a type of plant pigments, including α-carotene, β-carotene, etc. They are widely used as health supplements, food colorants, and feed additives.
• Astaxanthin: Anthocyanins are a type of plant pigment, which is a natural anti-inflammatory agent.
• Flavonoids: Flavonoids are a class of secondary metabolites that are widely present in many plants and have activities such as anti-cancer, anti-inflammatory, and antioxidant.
• Yellow pigments: Yellow pigments are a type of yellow pigment found in plants, including lutein, zeaxanthin, etc. Research shows that lutein and zeaxanthin have antioxidant and anti-inflammatory activities, which can prevent macular degeneration and slow down the progression of eye diseases.

Creative Biolabs has a variety of analytical methods, and we accurately analyze different types of plant pigments:

• High-performance liquid chromatography (HPLC): HPLC is a common technique for separating and quantifying plant pigments. We dissolve the sample in the mobile phase and use column packing to separate the different pigments, and then detect and quantify them through the detector.
• Mass spectrometry: We combine HPLC and mass spectrometry technology (LC-MS/MS) to more accurately identify and quantify plant pigments, which provides more detailed molecular information and helps identify unknown compounds.
• Ultraviolet-visible absorption spectroscopy (UV-Vis): UV-Vis spectroscopy is used to measure the absorbance of plant pigments, thereby determining their presence and concentration. This allows for rapid screening and quantitative analysis.
• Fluorescence spectrum analysis: It is used for qualitative and quantitative analysis of certain specific plant pigments. Plant pigments often emit fluorescent signals at specific wavelengths, and this method is highly sensitive to certain pigments.
• Infrared spectroscopy (IR): IR is used to study the functional groups and structure of plant pigment molecules. This technique helps confirm the molecular structure of certain plant pigments.

In addition to plant pigment analysis, as a professional analytical service company, Creative Biolabs also provides clients with high-quality and reliable other Plant Chemistry Profiling services in biomass, including Plant Cell Wall Analysis, Plant Elements, and Vitamin Profiling services.

Published data

The authors extracted natural pigments from the plant gooseberry and quantified them by HPLC. First, they freeze-dried ripe red and green gooseberries and then ground the dried samples into a uniform powder. Next, they mixed the freeze-dried powder with the extraction solvent and used citric acid-mediated ultrasound-assisted extraction (CA-UAE) to extract anthocyanins from gooseberries and conduct analysis and evaluation. Anthocyanins are water-soluble pigments in nature. They are flavonoids that usually exist in the form of glycosides and aglycones and have antioxidant activity. The authors identified and analyzed anthocyanins in currant extracts through spectroscopic and chromatographic techniques. The results showed that compared with traditional extraction methods, the content of target anthocyanins obtained by UAE extraction was higher. This research result promotes the development of using green extraction technology to extract natural anthocyanins, which is of great significance for environmental protection.

FAQs

Q1: What are your requirements for plant samples? Does it require special handling?

A1: We usually need to receive fresh or dried plant samples. If special handling is required, we provide detailed guidance, such as volatile solvent extraction or other pre-treatment steps.

Q2: What is the detection limit of your analytical method? How accurate is it?

A2: Our methods typically have very low detection limits, usually at ppm or lower. We ensure the accuracy of the analysis by using internal standards and calibration curves.

Q3: How do you process and analyze the resulting data? What contents will be included in the report?

A3: We use professional data processing software for data analysis and generate comprehensive analysis reports. Reports typically include the content of various plant pigments in the sample, their relative proportions, and possible assessment of biological activity.
