Plantago major L. in Vietnam was investigated for its chemical composition and also evaluated the biological activities against enzyme α- glucosidase and free radicals activities. The powder mixture of dried leave and roots of this species was extracted separately by three solvents: dichloromethane, water, water:alcohol (50:50, v:v). The chemical composition of dichloromethane extract was analyzed by GC-MS system to identify eighteen components, out of which eight biologically active compounds viz. 5-hydroxymethylfurfural, n-hecxadecanoic acid, 9,12-octadecadienoic acid (Z,Z)-methyl ester, allogibberic acid, β-tocopherol, campesterol, γ-sitosterol, lup-20(29)-en-3-ol and friedenlan-3-one were presented. The concentration of radical scavenging activity DPPH expressed by IC50 for water, water:alcohol (50:50, v:v) and dichloromethane with 208.7, 89.3 and 62.05 μg/mL, respectively. The dichloromethane, water and water:alcohol (50:50, v:v) extract of Plantago major exhibited α-glucosidase inhibitory activity with IC50 values of 116.4, 302.7, 195.9 μg/mL, respectively, which was comparable with acarbose (98.4 μg/mL). Plantago major L. in Vietnam may be effective inhibitors as the antidiabetic candidate and helpful to reduce the postprandial glucose levels.

There is a growing search in the chemical composition of essential oils, as they have biological and pharmacological activities. Among the plants with homogeneous composition in essential oils stands out the species Eremanthus arboreus (Gardner) MacLeish, (Asteraceae) popularly known as the “candeeiro”. This plant species is native to Chapada of Araripe - Ceará, Brazil. The objective was to characterize chemically the constituents of the essential oil (OE) of E. arboreus by means of Gas Chromatography and perform a review of its biological and pharmacological activities. The botanical material was collected in Chapada of Araripe, Barbalha - CE, Brazil, in April 2014, the extraction and collection of OE was done in Clevenger apparatus. The chemical composition of the OE was performed by Gas Chromatography coupled to Mass Spectrometry (CG/MS). As for the review, specialized scientific bases (Scopus, Scielo and Web of Science) were consulted. According to the results, 8 constituents were identified, where α-Bisabolol is mentioned as being the main component of the essential oil of this species. As for the biological and pharmacological activities of the OE, it was demonstrated that the species has the following activities: antimicrobial, larvicide, anti-inflammatory and antinociceptive. Eremanthus arboreus is a species with great pharmaceutical potential and also an alternative for industries that target products based on the constituent α-Bisabolol.

Flacourtiaceae plants are widely used as folk medicines in traditional medicine systems for its chemical diversity and pharmacological activities. In many different areas, Flacourtiaceae plants are used as traditional medicines for the treatment of ulcers, malaria, rheumatism. The Flacourtiaceae plants contain a very plentiful chemical composition, and phytochemical studies show that the Flacourtiaceae plants contained terpenoids, aromatic glycosides, flavnoids, phenylpropanoids, alkaloids, fatty hydrocarbon, and other compounds. In pharmacological studies, various extract and isolated individual compounds exhibited antitumor, anti-oxidation, and anti-inflammatory activities. In this review, the literature data on the chemical constituents and pharmacological investigations of the Flacourtiaceae plants are summarized, to provide information about a more comprehensive chemical composition and detailed pharmacological activities of Flacourtiaceae plants, with a view of further development of clinical medication. However, research on quantitative analysis, toxicity, and drug safety in vitro and in vivo is still insufficient, and further research is required.

Protium heptaphyllum is a plant widely distributed in Brazilian ecosystems that produce a resin which has pharmacological activities. In this study, the chemical composition, antimicrobial and antibiofilm activity, and the possible mechanism of action against the bacterium V. parahaemolyticus of essential oil from P. heptaphyllum (EOPH) were investigated. Twenty-two components were detected in EOPH, and β-phellandrene (60.68%) had the majority. The inhibition halo, MIC, and MBC values were 11 mm, 2 mg/mL, and 8 mg/mL, respectively. Biofilm biomass inhibition and biomass reduction of the preformed biofilm were detected at 4 mg/mL EOPH concentration. The assays of cell constituent release and membrane permeability indicated that EOPH may disrupt the cell membrane, leading to leakage of intracellular constituent as reducing sugars and materials with an absorbance of 260 nm.

Paeoniae Radix

The Paeoniae Radix Alba-Atractylodis Macrocephalae Rhizoma herbal pair is mainly used for regulating the functions of liver and spleen, benefitingqi, and nourishing blood. However, the bioactive compounds for the pharmacological activities of the crude and processed Paeoniae Radix Alba-Atractylodis Macrocephalae Rhizoma herbal pair extracts are still unclear to date. In the present study, Q Exactive high-performance benchtop quadrupole-Orbitrap LC-MS/MS was applied to identify the complicated components from crude and processed Paeoniae Radix Alba, crude and processed Atractylodis Macrocephalae Rhizoma, and their crude and processed herbal pair extracts. 123 and 101 compounds were identified in crude and processed Paeoniae Radix Alba samples, respectively. Meanwhile, 32 and 26 compounds were identified in crude and processed Atractylodis Macrocephalae Rhizoma samples, respectively. In the crude and processed Paeoniae Radix Alba-Atractylodis Macrocephalae Rhizoma herbal pair extracts, co-decoction could significantly change the chemical composition of Paeoniae Radix Alba and Atractylodis Macrocephalae Rhizoma in solution. The developed method may provide a scientific foundation for deeply elucidating the processing and compatibility mechanism of Paeoniae Radix Alba and Atractylodis Macrocephalae Rhizoma.

Current Review

The Willows (genus Salix), with more than 330–500 species and 200 hybrids, are trees, shrubs or prostrate plants that are widely distributed in Africa, North America, Europe, and Asia. The genus is traditionally used in folk medicine and represents a valuable source of biologically active compounds among them salicin, a prodrug for salicylic acid. Altogether, 322 secondary metabolites were characterized in the genus including flavonoids 94) (flavonols, flavones, flavanones, isoflavones, flavan-3-ols (catechins and procyanidins), chalcones, dihydrochalcone, anthocyanins, dihydroflavonols), phenolic glycosides (76), organic acids (28), and non-phenolic glycosides (17), sterols and terpenes (17), simple phenolics 13) and lignans 7) in addition to volatiles and fatty acids (69). Furthermore, willows exert analgesic, anti-inflammatory, antioxidant, anticancer, cytotoxic, antidiabetic, antimicrobial, antiobesity, neuroprotective and hepatoprotective activities. The current review provides an updated summary of the importance of willows, their chemical composition and pharmacological activities.
