Abstract Background Currently, although Inula nervosa Wall is well investigated, little is understood about blossoms of Inula nervosa Wall (BINW). Objective In this work, we systematically investigated the antioxidant activity of the extract from BINW by various standard assays including DPPH free radical ability, ABTS• +, and FRAP. Methods Chemical compounds are tentatively identified through an UHPLC-QTOF-MS system. Furthermore, the contents of nine compounds were detected with UHPLC method coupled with PDA. By carefully analyzing the quantitative data via clusters analysis and PCA. Results 46 compounds are tentatively identified and our results showed that 9 compound samples in 21 batches of BINW collected from different areas could be differentiated and analyzed by a heatmap visualization. In addition, the contents of nine compounds (flavonoids, phenolic acids) exhibited a total of higher amounts and better antioxidant activities from Yunnan than those from other three origins. Conclusions Our study not only developed a powerful platform to explain the difference traditional Chinese medicines (TCMs) species that in closely related through the chemometric and chemical profiling, but also presented a useful method to establish quality criteria of BINW with multiple origins. Highlights To detailly characterize the BINW, we not only performed DPPH, FRAP and ABTS assays to investigate its antioxidant activity, but also established UHPLC-QTOF-MS/MS and UHPLC-PDA based methods to comprehensively identify and qualitatively analyze its components.

Herbal medicines are the oldest and most widely used form of treatment for welfare of mankind. Herbal medicines possess strong reputation as complementary treatment across the globe due to their easy accessibility and safety. Particularly traditional Chinese medicines (TCM) are very popular due to their desirable therapeutic effects. They already have been proven for their remarkable potential in treatment of wide range of disease ailments. The major drawback in using herbal medicines is lack of standardisation aspects due to the complexity of chemical constituents. Pharmacokinetics study of such medicines helps forecast a range of events related to efficacy, safety, and toxicity profile of them. Apart from this, pharmacokinetics studies also recommended by various regulatory agencies during diverse stages of herbal drug development. Thus it is highly essential to have knowledge about the pharmacokinetic properties of any herbal drug. Thus it was thought that it will be worthwhile to compile the pharmacokinetic data of TCM which will be helpful for the researchers involved in further research on TCM. To portray entire picture about absorption, distribution, metabolism, and excretion (ADME) of some TCM, this well-designed scientific review covers the pharmacokinetic profile of 50 TCM available from 2003 and onwards.

Objective: The present work deals with the qualitative study of the phytoconstituents present in Aegialitis rotundifolia Roxb., ethanolic leaves extract and evaluate its antioxidant properties in vitro. Methods: The qualitative phytochemical analysis of the extract was performed first using preliminary phytochemical tests and then by liquid chromatography quadrupole-time-of-flight mass spectrometry (LC-Q-TOF-MS). The antioxidant properties were investigated comprehensively using seven in vitro models viz., 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, nitric oxide (NO) scavenging, hydrogen peroxide (H2O2) scavenging, superoxide (SOD) radical scavenging, lipid peroxidation (LPO) assay, reducing power (RP), and total antioxidant activity. Results: The preliminary phytochemical analysis revealed the presence of several important phytochemical groups whereas the LC-Q-TOF-MS analysis detected 25 phytoconstituents in the extract mostly belonging to flavonoids and alkaloids. The test extract showed strong dose-dependent antioxidant activity in all the seven in vitro models, however, the activity of the extracts was slightly lower compared to the reference standard ascorbic acid. Conclusion: The test extract showed strong antioxidant properties which could be possibly due to the phytoconstituents detected in the extract.
