“…In the recent years, on-line HPLC-2,2, diphenyl-1-picrylhydrazyl radical (DPPH•) assay had been additionally used to effectively screen for the fast identification of antioxidant compounds from herbal extracts [ 83 , 84 ]. A simultaneous detection and quantification of compounds in complex plant matrices with high antioxidant potentials have also been investigated through on-line HPLC-UV-DPPH• analysis [ 2 , 3 ]. This technique was used by Damašius et al [ 2 ] on extracts from different species of Lamiaceae family ( Table 2 ).…”

“…Concerns over possible adverse health effects of commonly used synthetic antioxidants such as butylated hydroxytoluene (BHT) or butylated hydroxyanisole (BHA) have driven research interests towards finding antioxidants from natural sources, mainly from commonly consumed foods [ 1 , 2 ]. Terrestrial plants constitute one of the most valuable sources of natural antioxidants in addition to other health-promoting phytochemicals [ 3 ]. In particular, herbs and spices have shown strong antioxidant activities owing to their high content of polyphenols [ 2 , 4 ].…”

“…Considerable attention has been paid to the bioactive compounds in herbs and spices in an effort to reveal their potential contribution to health and the preservation of food quality [ 5 , 6 ]. Several previous studies have suggested that polyphenols from natural sources could be a potential alternative to the use of synthetic antioxidants [ 3 , 4 ]. These antioxidants have many advantages over their synthetic equivalents including consumer acceptance, and the reduced regulatory requirements based on their safety [ 7 ].…”

“…Epidemiological findings as well as scientific data have shown that a diet rich in polyphenols, such as flavonoids and hydroxycinnamic acids, has effective health effects [ 10 , 11 , 12 , 13 ] and could confer protection against the risks of degenerative diseases, e.g., cardiovascular diseases [ 12 ]. Therefore, further studies are essential in streamlining the various stages of novel functional food formulations, through improving their health benefits and assuring antioxidant and antimicrobial safety [ 3 , 14 ].…”

“…Several thousand polyphenols have been reported in higher plants [ 15 ] and this structural diversity is one of the factors contributing to the complexity of their analysis [ 17 ]. Compounded to this is the huge variation in the levels of these compounds in different plant species [ 3 ]. The need for sensitive and accurate methods for the analysis of polyphenols is essential, as knowledge of dosage are prerequisites in evaluating health claims of food components.…”

Lamiaceae species are promising potential sources of natural antioxidants, owing to their high polyphenol content. In addition, increasing scientific and epidemiological evidence have associated consumption of foods rich in polyphenols with health benefits such as decreased risk of cardiovascular diseases mediated through anti-inflammatory effects. The complex and diverse nature of polyphenols and the huge variation in their levels in commonly consumed herbs make their analysis challenging. Innovative robust analytical tools are constantly developing to meet these challenges. In this review, we present advances in the state of the art for the identification and quantification of polyphenols in Lamiaceae species. Novel chromatographic techniques that have been employed in the past decades are discussed, ranging from ultra-high-pressure liquid chromatography to hyphenated spectroscopic methods, whereas performance characteristics such as selectivity and specificity are also summarized.

Panzerina lanata is a Chinese medicine with the bioactivity of detumescence and detoxification. In this study, novel qualitative and quantitative methods were established by ultra‐high performance liquid chromatography‐quadrupole time‐of‐flight mass spectrometry and ultra‐high‐performance liquid chromatography‐triple quadrupole linear ion trap mass spectrometry, respectively. As a result, 20 compounds were identified or tentatively characterized including flavonoids, organic acids, alkaloids, and lignans, five of which were identified for the first time based on the reference standards. The quantitative approach exhibited good linearity (R2 > 0.995), precision (RSDs < 4.97%), stability (RSDs < 4.77%), and recovery (96.04‐104.14%). Afterward, this method was implemented to determine 11 flavonoids in four batches of P. lanata. Among them, seven compounds were quantified for the first time. Narcissin was abundant in each batch of P. lanata (average of 10.890‐14.230 mg/g) with the highest quantities. The results provide valuable information for quality evaluation.

Rationale: The main feature of the fragmentation of [M − H] − ions of methoxylated flavonoids is the loss of methyl radical (formation of the [M − H − CH 3 ] −• product ion). Subsequent decomposition of [M − H − CH 3 ] −• product ions may be useful for identification of a given compound by HPLC/MS. This paper describes how the selected diagnostic fragment ions can be useful during HPLC/MS(−) analysis of methoxylated flavonoids. Methods: Product ion spectra (ESI-CID-MS/MS spectra) of [M − H] − ions of 17 methoxylated flavonoids (flavones, isoflavones and flavonols) were obtained with a Q-TOF mass spectrometer. Full scan mass spectra (ESI-MS) were obtained with a single quadrupole type of instrument. Results: A number of product ions were recognized as useful from the point of view of structural elucidation. In most cases they were diagnostic product ions, formed as a result of C ring breaking. Conclusions: The most important conclusions drawn from this study are: the product ion at m/z 132 indicates that the analysed compound is an isoflavone; the product ion at m/z 117 indicates the presence of one hydroxy group at ring B or at the 3-position; biochanin A and prunetin can be differentiated by their 'in-source' fragmentation, by the relative abundances of product ions at m/z 195, 183 and 167; loss of mass 102 from the [M − H − CH 3 ] −• ion indicates that ring B is not substituted and there is no hydroxy group at the 3-position; and rhamnetin can be detected using three diagnostic product ions, namely at m/z 121, 165 and 193.
