Project description
|
Lobelia chinensis Lour. (L. chinensis) has traditionally been used as a treatment for snake bites, high fever, jaundice, edema, and diarrhea, and modern studies have reported its anti-inflammatory, antioxidant, and antiviral activities. L. chinensis contains various compounds, such as flavonoids and coumarins, and its flavonoid components have been identified in many studies. In this study, a high-performance liquid chromatograph equipped with a photodiode array (PDA) detector and an Aegispak C18-L reverse-phase column (4.6 mm × 250 mm i.d., 5 μm) was used to simultaneously analyze four marker components in L. chinensis for standardization purposes. HPLC-PDA (detection at 340 nm), performed using a 0.1% formic acid-water/0.1% formic acid-acetonitrile gradient, separated the four marker compounds: luteolin-7-O-β-d-glucuronopyranosyl (1→2)-O-β-d-glucuronopyranoside, clerodendrin, chrysoeriol-7-O-diglucuronide, and diosmin. The developed analytical method showed excellent linearity values (r2 > 0.9991), limits of detection (LODs: 0.376–2.152 μg/mL), limits of quantification (LOQs: 1.147–6.521 μg/mL), intra- and inter-day precisions (RSD < 1.96%), and analyte recoveries (96.83–127.07%; RSD < 1.73%); thus, it was found to be suitable for the simultaneous analysis of these four marker compounds in L. chinensis.

Lobelia chinensis Lour. (L. chinensis)은 전통적으로 뱀 물림, 고열, 황달, 부종 및 설사 치료로 사용되었으며, 현대 연구에서 항염, 항산화 및 항바이러스 활성이 보고되었다. L. chinensis에는 플라보노이드와 쿠마린과 같은 다양한 화합물이 포함되어 있다. 본 연구에서는 L. chinensis의 표준화를 위해 네 개의 표지 성분을 동시에 분석하기 위해 PDA와 Aegispak C18-L 역상 칼럼 (4.6 mm × 250 mm i.d., 5 μm)이 장착된 고성능 액체 크로마토그래프가 사용되었습니다. HPLC-PDA (340 nm에서 검출), 0.1% formic acid-water/0.1% formic acid-formic acid-acetonitrile gradient를 사용하여 네 개의 표지 성분 : luteolin-7-O-β-d-glucuronopyranosyl (1→2)-O-β-d-glucuronopyranoside, clerodendrin, chrysoeriol-7-O-diglucuronide, and diosmin을 분리하였다. 개발된 분석 방법은 우수한 선형성 값 (r2 > 0.9991), 검출 한계 (LOD : 0.376-2.152 μg/mL), 정량 한계 (LOQ : 1.147-6.521 μg/mL), 일 내/간 내 정밀도 (RSD <1.96%) 및 분석 물질 회수 (96.83-127.07%; RSD <1.73%)를 보였으므로, L. chinensis의 이 네 가지 표지 성분을 동시에 분석하기에 적합한 것으로 판단된다.
