Characterization of Polyphenols and Volatile Compounds from Understudied Algerian Pallenis spinosa by HS-SPME-GC-MS, NMR and HPLC-MSn
Abstract: Pallenis spinosa (L.) Cass. is a widespread plant in the Mediterranean region. Traditionally, it is used as a medicinal species to treat several ailments, from inflammation to skin injuries. Although the phytochemical content of this plant has already been investigated, there is currently limited data on Algerian P. spinosa. In this work, we focused on volatile compounds and non-volatile secondary metabolites extracted using HS-SPME and methanol from the aerial parts of P. spinosa collected from Northeast Algeria. Volatile constituents were analyzed by GC-MS, while non-volatile compounds were analyzed by NMR and HPLC-MSn . In total, 48 volatile compounds were identified, including sesquiterpene hydrocarbons (65.8%), monoterpene hydrocarbons (16.9%), and oxygenated monoterpenes and sesquiterpenes (8.3% and 6.5%, respectively). β-Chamigrene (16.2%), α-selinene (12.8%), β-pinene (10.6%), and β-caryophyllene (9.2%) were assessed as the main constituents. Concerning non-volatile metabolites, 23 polyphenols were identified (7.26 mg/g DW), and phenolic acids were predominant (5.83 mg/g DW). Tricaffeoylhexaric acid (1.76 mg/g DW), tetracaffeoylhexaric acid (1.41 mg/g DW), 3,5-dicaffeoylquinic acid (1.04 mg/g DW), caffeoyl dihexoside (0.35 mg/g DW), and chlorogenic acid (0.29 mg/g DW) were the most abundant ones. Several known flavonoids, such as tricin and patuletin glycosides, kaempferol, and apigenin, were also identified, and myricetin hexoside was detected in P. spinosa for the first time. Overall, our work is the first to report an exhaustive characterization of volatile and non-volatile secondary metabolites from Algerian P. spinosa. The results represent a step forward in revealing the chemistry of this widespread plant species. Furthermore, they may contribute to rationalizing its traditional medicinal applications and preserve the biodiversity of Algerian flora. Keywords: Pallenis spinosa; secondary metabolites; terpenes; polyphenols; headspace analysis; mass spectrometry

IRIDOIDS AND FLAVONOIDS PRESENT IN DECOCTIONS FROM AERIAL PARTS OF VERBASCUM BETONICIFOLIUM
Introduction: Verbascum L. is the largest genus of the Scrophulariaceae family, which comprises more than 300 species of wild growing plants, Verbascum betonicifolium (V. betonicifolium) is a plant used in traditional medicine for several ailments. The objective of this study was to determine the first phytochemical characterization of aqueous extracts from aerial parts. Methods: The compounds present in the aerial part aqueous extract were identified by high performance liquid chromatography, coupled to a diode-array detector (HPLC-DAD) and by high-resolution mass spectrometry (HRMS), using LC–MS/MS analyses. Results: Six types of plant metabolites were found: primary metabolites like malic, gluconic and citric acids, representing 36 % of the identified compounds; secondary metabolites like flavonoid derivatives (apigenin, luteolin) and several glycosylated derivatives, representing 27 % of the identified compounds; caffeic acid derivatives (chlorogenic acid) and several flavonoid derivatives representing 9 % of the identified compounds; iridoids like methylscutelloside, scropheanoside, saccatoside and so on, representing 30 % of the identified compounds; one lignan and a lactone sesquiterpenoid were also tentatively suggested.Conclusions: These results show for the first time the richness of phytochemicals of V. betonicifolium and that the aqueous extract could be used as new natural sources of bioactive molecules.

Effects of pre-treatment on seeds germination in vitro and in soil of some medicinal plants
Actuellement, les plantes médicinales (PM) représentent une source considérable et permanente pour les principes actifs. Parmi les plantes médicinales industrialisées et commercialisées en Algérie, on trouve le Cuminum cyminum, Ocimum basilicum, Pimpinella anisum et Mentha pulegium. Parmi les mesures qui pourraient contribuer au redressement de ce secteur, nous citons l’instauration des surfaces cultivées des plantes médicinales. Ainsi, le semis, le bouturage et la culture in vitro qui pourraient être un moyen de production et d’approvisionnement en plantes médicinales. Ce travail expérimental sur la performance germinative des graines de C. cyminum, O. basilicum et P. anisum, dans le but de déterminer le taux de germination et la croissance dans 5semaines sans traitement dans la serre et avec traitement in vitro. Selon les espèces, les taux de germination presque sont homogènes dans les 2 compartiments de P. anisum et C. cyminum obtenu pour une durée de germination de 2 à 5 semaine tandis que l’O. basilicum a montré un retard dans la germination au cours de 3 premières semaines dans la serre, contrairement in vitro,ou il’a montré dès la 1ère semaine, et cela indique la nécessité de traiter les graines pour raccourcir le temps de germination. Ce travail expérimental aussi, a pour but la multiplication de M. pulegium par bouturage et culture in vitro, la culture in vitro donne des bons résultats concernant la multiplication de M. pulegium selon les paramètres de croissance (tige, racine, feuille et nœud) par rapport au bouturage.
