The objective of this study was to evaluate the free radical scavenging potential and high performance thin layer chromatography (HPTLC) fingerprinting of (). Phytochemical analysis was carried out using standard methods, and free radical scavenging activity of the plant was determined using 2,2-diphenyl-1-picrylhydrazy (DPPH), nitric oxide (NO) and superoxide anion ([Formula: see text]) radical scavenging capacities. HPTLC plate was kept in CAMAG TLC Scanner 3 and the Rf values at fingerprint data were recorded by WINCATS software. Aqueous extract of reliably showed the total phenolics (267.2±2.42 mg/g), flavonoids (75.43±3.36 mg/g) and antioxidants (349.11±8.04 mg/g). The extract was found to have DPPH (52.08%), NO (23.12%) and [Formula: see text] (26.79%) scavenging activities at the concentration of 250 μg/mL and the results were statistically significant compared with ascorbic acid standard (<0.05). HPTLC results confirmed that the extract contained several potential active components such as phenols, flavonoids, saponins and terpenoids as the slides revealed multi-colored bands of varying intensities. This study confirmed that the plant had multipotential antioxidant and free radicals scavenging activities.
本研究的目的是评估()的自由基清除潜力和高效薄层色谱(HPTLC)指纹图谱。采用标准方法进行植物化学分析,并使用2,2-二苯基-1-苦基肼(DPPH)、一氧化氮(NO)和超氧阴离子([公式:见正文])自由基清除能力来测定该植物的自由基清除活性。将HPTLC板置于CAMAG TLC Scanner 3中,并通过WINCATS软件记录指纹数据的比移值(Rf)。()的水提取物可靠地显示出总酚含量(267.2±2.42毫克/克)、黄酮类化合物含量(75.43±3.36毫克/克)和抗氧化剂含量(349.11±8.04毫克/克)。在250微克/毫升的浓度下,发现该提取物具有DPPH清除活性(52.08%)、NO清除活性(23.12%)和[公式:见正文]清除活性(26.79%),与抗坏血酸标准品相比,结果具有统计学意义(<0.05)。HPTLC结果证实,该提取物含有几种潜在的活性成分,如酚类、黄酮类、皂苷类和萜类,因为薄层板显示出不同强度的多色条带。本研究证实该植物具有多种抗氧化和自由基清除活性。
