Topic Information

Dear Colleagues,

Separation is one of the chemical reactions that occurs between compounds and solid phases and/or mobile phases. Their combinations are infinite, and every compound should be separated into a single pure form. We are happy to invite colleagues to submit papers outlining examples of compounds and their separation methods.

In addition to this, plants are widely recognized as one of the biggest sources of active compounds used in medicine and functional foods. However, there are various plants yet to be investigated for new novel compounds.

Thus, this Topic is focused on the purification of bioactive natural products from plant resources as well as the various chromatography approaches to analyse these products, including GC and HPLC. Papers on the isolation and structural determination of novel compounds of plant origin, as well as on methods used for their analysis, are welcome for submission.

Flavonoids are one of the most essential compounds in various plants. This study used the cellulase-assisted method to extract flavonoid-enriched antioxidants from Equisetum arvense L. (EAL). According to a three-factor and three-level central composite design, the response surface methodology was used to obtain the maximum total flavonoid yield, thereby providing the most potent antioxidant activity of EAL extracts. The results indicated that the optimal condition for the total flavonoid extraction was 0.52% (base substrate) enzyme concentration and enzymolysis for 50.58 min at 49.03 °C. The extraction rate of flavonoids from horsetail reached 4.88 mg/g under these optimal conditions. The yield was 51.23% higher than that from the traditional solid–liquid extraction method. The highest DPPH-scavenging ability of the extracts obtained under 0.50% enzyme concentration and enzymolysis for 49.41 min at 46.59 °C was 77.36%. HPLC results revealed that the antioxidant substances had diverse flavonoids. Thus, the extraction condition was consistent for antioxidant activity and total flavonoids. Therefore, the current study provided an efficient method to extract flavonoid compounds from EAL, facilitating technical support for utilizing the plant. Full article
