“…Overall, D. maritima aerial parts extracts showed higher flavonoid content compared to bulbs, particularly for anthocyanins and flavones, which were best extracted in water and methanol solvents. The results were in agreement with Vega and Martin [ 30 ], who found cyanidin-3-monoglucoside as the most abundant anthocyanin in the aerial parts of Urginea maritima Baker. In accordance to the literature, the OPLS-DA model of the D. maritima aerial parts reported classes of flavonoid and anthocyanin compounds (e.g., pelargonidin, apigenin, and isorhamnetin 3- O -glucuronide), to be the best discriminants in D. maritima extracts [ 22 , 31 ].…”

Drimia maritima (L.) Stearn (squill), belonging to the Asparagaceae family, is acknowledged as a medicinally valuable species from the Drimia genera. In this study, water, methanol, and ethyl acetate extracts of D. maritima aerial parts and bulbs were investigated for their polyphenols profile and evaluated for their antioxidant and enzyme inhibition properties. Phenolics were profiled through an untargeted metabolomics approach using an ultra-high pressure liquid chromatograph coupled to quadrupole-time-of-flight mass spectrometry (UHPLC-QTOF-MS). This analysis revealed an enrichment of low molecular weight phenolics and flavonoids in the aerial parts of D. maritima, while lignans mainly characterized bulb extracts. Antioxidant capacity was investigated by different assays, including phosphomolybdenum assays, radical scavenging (DPPH: 2,2-diphenyl-1-picrylhydrazyl; ABTS: 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)), as well as reducing ability (CUPRAC: cupric reducing antioxidant capacity; FRAP: ferric reducing antioxidant power), and metal chelating. In radical scavenging and reducing power assays, the water extract of aerial parts exhibited the strongest ability (DPPH: 36.99 mg trolox equivalent (TE)/g; ABTS: 85.96 mg TE/g; CUPRAC: 87.37 mg TE/g; FRAP: 55.43 mg TE/g). In general, the ethyl acetate extracts from aerial parts and bulbs provided the weakest antioxidant capacity. Concerning enzyme inhibitory activities, the water extracts of the bulb were poorly active, while the ethyl acetate extracts from both plant portions displayed the best α-amylase inhibitory abilities. The best acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) abilities were recorded by ethyl acetate extract of aerial parts (2.36 mg galantamine equivalent (GALAE)/g) and bulbs (5.10 mg GALAE/g), respectively. Overall, these results support the medicinal aptitude of D. maritima and its possible use as a natural source of antioxidants and enzyme inhibitors with functional potential.

“…Table 3) Anthocyanins Compound 7 showed an absorption maximum at around 514 nm. Mass spectrometric experiments revealed a molecular ion at m/z 447 in the negative ionization mode, and MS 2 data showed a fragment ion at m/z 285, corresponding to the mass spectrometric behavior of cyanidin-3-O-glucoside (chrysanthemin) [14]. Compound 7 was found in the outer fresh scales, pads, and roots.…”

“…Unfortunately, co-extracted compounds like flavonoids were separated by precipitation and were not considered in these studies. However, emanating from the intense color of red sea squill, anthocyanins and other flavonoids have been analyzed in further studies by paper chromatography and thin layer chromatography (TLC) [12][13][14]. Due to the lack of more sophisticated analytical tools at those times, these studies should now be critically reviewed.…”

Mediterranean sea squill (Drimia maritima (L.) Stearn) is used in the production of medicinal products. Current HPLC methods comprise tedious sample clean-up and have been merely focused on the analysis of cardiac glycosides, whereas a thorough characterization of D. maritima considering both the latter compound class and more hydrophilic secondary metabolites in one HPLC run has not been performed so far. Consequently, a novel HPLC-DAD-MS(n) method has been developed allowing the simultaneous determination of both cardiac glycosides and phenolic compounds, which is characterized by simplified sample preparation. This method was applied to characterize sea squill, revealing a complex profile of its extractive compounds derived from the two classes. Furthermore, the potential of the method reported here to quantitate the predominant compounds, i.e., dihydroquercetin derivatives and bufadienolides, was demonstrated. The occurrence of phenolic compounds, not described for sea squill so far, and of characteristic compounds specific to individual plant parts or vegetation stages was further addressed. The data revealed that classification of various vegetation phases based on quantitative evaluation of bufadienolides and dihydroquercetin derivatives applying principal component analysis (PCA) appears possible. Thus, the methodology presented here forms the basis for future routine application in quality control of raw materials and pharmaceutical preparations derived from sea squill. This will allow systematic comparison of different plant parts, vegetation stages and origins based on an extended sample set.
