What Is Kaempferol?

Kaempferol Extract is a natural flavonoid compound extracted from plants, generally found in fruits, vegetables, herbs, such as apples, onions, broccoli, ginkgo leaves, tea, red wine, etc. Due to anti-inflammatory, antioxidant, neuroprotective, and cardiovascular effects,kaempferol powder

has attracted much attention in the fields of health products, cosmetics, and drug development.

Kaempferol Test Method

Kaempferol Extract detection mainly relies on chromatographic and spectroscopic techniques. The following are the differences between each detection method:

Test method	Sensitivity	Applicable samples	Main purpose
HPLC-UV	High	Plants and food	Conventional quantification
TLC	Low	Plant extracts	Rapid screening
UV-Vis	Medium	Purest quality	Rough quantification

1.HPLC-UV

HPLC-UV is a combination of high-performance liquid chromatography. It is composed of components such as infusion pump, sampler, chromatographic column, UV detector, column temperature chamber, and data processing system working together. A chromatographic column needs to be prepared for observation, and a standard solution of kaempferol needs to be prepared as the control group. The sample also needs to be pre processed. In this method, conclusions will be drawn in terms of linear range, detection limit, quantification limit, precision, recovery rate, stability, and other aspects. Although the solvent consumption of this method is relatively high, it has the characteristics of high sensitivity, wide applicability, and high degree of automation.

2.TLC

TLC is a simple, efficient, and economical separation technology. Separate and obtain characteristic parameters by analyzing the distribution coefficient differences between different compounds in the adsorbent and developing agent. The system consists of a thin-layer plate, unfolding groove, sampler, unfolding agent, detection system, etc. Operate through steps such as board making, sampling, unfolding, and color development. Although the quantitative accuracy is limited, a certain degree of quantitative analysis can still be conducted.

3.UV-Vis

UV-Vis is a technique for analyzing the absorption of electromagnetic radiation in the ultraviolet and visible light regions by different substances. The operation was carried out using principles such as electronic transition, Lambert Beer law, and characteristic absorption of kaempferol. The instrument components include light source, monochromator, sample chamber, detector, data processing, etc. Although the selectivity is poor and the sensitivity is low, the operation is simple and fast, the equipment popularity is high, and the maintenance cost is low.

Kaempferol Benefits

Kaempferol Extract is a multifunctional natural active ingredient with the following benefits:

1. Anti inflammatory and antioxidant properties
By clearing free radicals and inhibiting the expression of inflammatory factors, antioxidant enzyme activity can be enhanced and pro-inflammatory factors can be reduced.

2. Protect cardiovascular and neurological health
By reducing the expression of bad cholesterol, inhibiting abnormal proliferation of vascular smooth muscle cells, protecting dopamine neurons,can lower blood lipids, resist arteriosclerosis, and alleviate Alzheimer's disease.

3. Antibacterial and antiviral
By inhibiting the activity of neuraminidase and blocking virus entry into cells,can resist Staphylococcus aureus, influenza virus, etc.

4. Protect bone health
By enhancing osteoblast differentiation, improving ALP activity, and reducing osteoclast activity, bone formation can be promoted and osteoporosis can be prevented.
