What are the common plant extract manufacturing detection methods in the plant extraction industry? Today we will bring you HPLC detection methods. Let’s see what is HPLC? What is the HPLC process?

What is HPLC?

HPLC stands for High Performance Liquid Chromatography. It also known ashigh pressure liquid chromatography,” “high speed liquid chromatography,” “high resolution liquid chromatography,” “modern column chromatography” dan sebagainya.

High performance liquid chromatography (HPLC) is an analytical method in the late 1960s. In recent years, it widely uses in the separation and determination of functional components of health food, nutritional fortifiers, vitamins and proteins. About 80% of organic compounds in the world can be analyzed by HPLC.

Characteristics of HPLC

High performance liquid chromatography (HPLC) has the characteristics of high pressure, high efficiency, high speed, high sensitivity and high selectivity. It widely uses in pharmaceutical, environmental protection, petrochemical, food, chemical and other industries. And is now an important method for separation and analysis.

Flow Chart for High Performance Liquid Chromatography

The solvent in the liquid storage bottle is sucked into the chromatography system by the pump. And then output, and after the flow and pressure measurement, it imports into the sampler. The detected object injects into the sample injector and passes through the column with the mobile phase. After separation on the column, the detected signal collects and processes by the data processing equipment, and the chromatogram records. Waste liquid flows into the waste liquid bottle. The gradient controller can also use for gradient elution in the case of complex mixture separation. This is similar to the programmed temperature of gas chromatography, except that gas chromatography changes the temperature. While HPLC changes the polarity of the mobile phase, so that the sample components can separate under the best conditions.

The separation process of high performance liquid chromatography

Like other chromatographic processes, HPLC is a continuous multi-exchange process between the stationary phase and the mobile phase. It separates different solutes by the difference of partition coefficient, affinity, adsorption force or molecular size between two phases.

Start the sample by adding it to the stigma. Assume that the sample contains 3 components, A, B and C, which enter the column along with the mobile phase and begin to be divided between the stationary phase and the mobile phase. The component A with small partition coefficient is not easily blocked by the stationary phase and flows out of the column earlier. The component C with a large partition coefficient stayed on the stationary phase for a long time and left the column later. The partition coefficient of component B is between A and C, and the second flows out of the column. If a mixture containing multiple components enters the system, each component in the mixture flows out of the column. According to its partition coefficient between the two phases in different order to achieve the purpose of separation.

The separation of different components in the chromatographic process depends first on whether there are differences in the partition coefficient, adsorption capacity and affinity of each component between the two phases, which is a thermodynamic equilibrium problem and the primary condition for separation. Secondly, when the different components move in the column, the spectral band is broadened with the column length, and the separation is related to the diffusion coefficient between the two phases, the size of the stationary phase, the packing of the column and the flow rate of the mobile phase. Oleh itu, the final effect of separation is the comprehensive benefit of both thermodynamics and kinetics.

Plant extract manufacturing process is from the plant as raw materials. Through physical and chemical extraction separation to obtain some or more active ingredients in the plant.

Although plant extract manufacturing process come in many forms, they share a common feature. The extracts represent naturally occurring phytochemicals that removes from the inert structure of the plant that produced them. The main advantage of using extracts from plants is that phytochemicals are more easy to absorb.

Application areas of plant extracts:

  1. Food Stuffs

According to the different needs of different people and different physiological conditions, as well as the principle of nutritional diet and physiological function adjustment. The food formula with different nutritional and health care functions designs in a targeted manner. And a large number of experiments also conducts to confirm that these different formulations of food do have their own required functional properties.

  1. suapan

The new variety feed has listed 117 kinds of natural plants that can be fed with the same food and medicine. In the catalogue of feed additives, 12 kinds of plant extracts such as Eucommia ulmoides leaf extract lists. These raw materials and additives use for animal intestinal health and immunity.

  1. Health Products

Used to improve memory, anti-keletihan; Stress; Mengawal lipid darah; Gastrointestinal function; Sleep; Anaemia; Protection against chemical liver damage; Milk secretion; Visual fatigue; Promoting lead removal; Beauty; Hair care.

  1. API

Pada masa ini, pharmaceutical active ingredients obtains from plant extracts: such as paclitaxel. Ginsenosides, dan lain-lain.

  1. Daily Chemicals and Cosmetics

It can be used for moisturizing cosmetics, water and oil balance, skin problems, dan lain-lain.

  1. Natural pigment

With roots, batang, daun, bunga, buah-buahan, dan lain-lain. of widely cultivated plants as initial materials. The color organic matter extractes from appropriate solvent and prepared by separation, refining and drying process. This kind of organic matter calls natural pigment of plant extract. Pada masa ini, terdapat lebih daripada 40 kinds of main natural pigments on the market. Such as capsicum red pigment, marigold extract, gardenia yellow pigment, curcumin and so on.

  1. Natural sweeteners

Natural sweeteners are commonly referred to as natural sweeteners when the sweeteners are extracted and processed from natural plants. According to the sweetness, it can be divided into low-fold sweeteners such as sucrose, beet sugar. And high-power sweeteners such as stevioside, grosvenor momordica fruit sweetener, rubiside, liquorice extract, neohesperidin dihydrochalcone and the like. The gradual replacement of sugar with natural high-power sweeteners is currently the main trend in the food and beverage industry.
