The Reseda genus is found in the Mediterranean and the Southwestern Asian areas [1]. In Algeria, there are twenty two species and subspecies [2, 3]. Eight flavones [4–9], sixteen flavonols [7, 8, 10–16], and one isoflavone [13] have been reported from the genus Reseda. R. villosa (Resedaceae) is an endemic species [1] collected from Ghardaia (Septentrional(More)
The essential oils obtained from Origanum glandulosum Desf., collected from two different localities of north-eastern Algeria, Constantine and Jijel, and from O. syriacum var. syriacum grown at El-Aghwar (northern Jordan) and El-Shubak (southern Jordan), were analyzed by GC-MS. p-Cymene (6.6% and 7.5%) and gamma-terpinene (13.4% and 14.5%) were found in O.(More)
The genus Eryngium belongs to the Apiaceae family (Umbelliferae), subfamily Saniculoideae, which consists of about 300 species [1]. Plants of this genus have shown various activities such as anti-inflammatory [2], antimalaria and antifungal [3], antioxidant and antimicrobial [4], antidiabetic [5], and analgesic properties [6]. Air-dried and powdered aerial(More)

Convolvulus is a fairly large genus with 250 species, almost cosmopolitan in distribution 1 . Various biological activities such as anticancer [2], antinociceptive [3], antidiarrhea [4], and antifungal [5] have been reported for Convolvulus species, which are characterized by the presence of phenolic compounds and alkaloids [6–9]. Algerian flora is(More)
A pentacyclic triterpene, named salvibuchanic acid (1), together with five known compounds, were isolated from the roots of Salvia buchananii Hedge (Lamiaceae). The structural characterisation of all compounds was performed by spectroscopic analyses, including 1D and 2D NMR and HRESIMS experiments. The lupane triterpene (1) and hyptadienic acid (2) were(More)
A previously undescribed phenolic sulphate ester, potassium 34-dihydroxy-3-methoxybenzoic acid methyl ester-5-sulphate (1), along with nine known flavonoids, kaempferol-3-O-potassium sulphate-4',7-dimethyl ether (2), kaempferol-4',7-dimethyl ether (3), rhamnocitrin-3-O-potassium sulphate (4), rhamnocitrin (5), kaempferol (6), quercetin (7), afzelin (8),(More)
A new 2-alkylhydroquinone glucoside, 1-O-β-d-glucopyranosyl-1,4-dihydroxy-2-((E) 2-oxo-3-butenyl)benzene (1), in addition to nine known compounds were isolated from the aerial parts of Phagnalon saxatile (L.) Cass. (Asteraceae). Their structures were identified based on spectroscopic methods including 1D and 2D NMR, mass spectrometry (HR-ESI-MS), UV(More)
