Investigating Flavonoids and biological activities of Curcuma aromatica Salisb extracts
Abstract
In this study, the raw material is white turmeric (Aromatica Salisb extracts) grown and harvested in the Prong Pak district, Dak Lak province. The material powder is extracted with 4 solvents (ethyl acetate, ethanol, acetone, and petroleum ether) using the soaking method to obtain the corresponding extracts. Then, the extract with the highest flavonoid content was determined for biological activities, including antioxidant, microorganisms, and anti-inflammatory activities. The results of investigating antioxidant activity using the DPPH method showed that white turmeric extract exhibited the ability to resist DPPH free radicals with an IC50 value = 837.06 ± 1.34 µg.mL-1. Results of investigating the antibacterial activity of white turmeric extract using the agar plate diffusion method showed that the extract displayed the ability to inhibit 7 types of pathogenic microorganisms. However, white turmeric extract had weak anti-inflammatory properties.
Tóm tắt
Trong nghiên cứu này, nguyên liệu được sử dụng là củ nghệ trắng (Aromatica Salisb extracts) được trồng và thu hoạch tại huyện Prông Pắk, tỉnh Đắk Lắk. Bột nguyên liệu được chiết flavonoid bằng 4 loại dung môi (ethyl acetate, ethanol, acetone và petroleum ether) bằng phương pháp ngâm để thu được cao chiết tương ứng. Tiếp theo đó, cao chiết có hàm lượng flavonoid cao nhất được xác định hoạt tính sinh học, bao gồm: hoạt tính kháng oxy hóa, kháng vi sinh vật và kháng viêm. Kết quả khảo sát hoạt tính kháng oxy hóa bằng phương pháp DPPH cho thấy cao chiết củ nghệ trắng có khả năng kháng gốc tự do DPPH với giá trị IC50 = 837,06 ± 1,34 µg.mL-1. Kết quả khảo sát hoạt tính kháng vi sinh vật của cao chiết củ nghệ trắng bằng phương pháp khuếch tán qua đĩa thạch cho thấy cao chiết có khả năng ức chế 7 loại vi sinh vật gây bệnh. Tuy nhiên, cao chiết nghệ trắng có tính kháng viêm yếu.
