The Eugenia genus is rich in bioactive substances with biological potential. Mollicutes are bacteria without cell walls, which are responsible for various human and animal diseases. The aim of this study was to evaluate the chemical composition and antimollicute activity of Eugenia mattosii. Leaves and stems were extracted with methanol, partitioned into fractions of different polarities, and submitted to column chromatography in order to isolate major compounds. Identification and quantification of isolated substances in extracts and fractions were performed by UPLC-PDA/ESI+ - QTOF. Methanolic extracts, ethyl acetate and chloroform fractions and isolated substances were screened for antimycoplasmic activity against five Mycoplasma strains. The methanolic extracts of leaves and stems showed moderate antimycoplasmic activity (MICs = 250-500 μg.mL-1). The fractions exhibited better effect, with MICs = 125-1000 μg.mL-1, especially the ethyl acetate fraction of the leaves, which presented MICs of 125-250 μg.mL-1 for all strains tested. Phytochemical analyses evidenced the presence of some phenolic compounds, including pinostrobin, cryptostrobin and catechin, the first showing promising antimycoplasmic activity. Quantification of the compounds demonstrated higher concentrations of pinostrobin and cryptostrobin in the chloroform fraction. In conclusion, E. mattosii presented antimycoplasmic activity related, at least in part, to the presence of pinostrobin.

Positive Results

Thelechitonia trilobata is regarded as a troublesome weed that grows to form a dense blanket over the soil preventing the growth of other crops in farmland. Although the plant is regarded as a notorious, invasive plant, its chemical composition and biological potential have not been reported. The essential oil was isolated from the fresh leaves of T. trilobata using hydrodistillation. α-Pinene (21.6%), α-phellendrene (21.0%), limonene (12.8%) and germacrene D (7.5%) were the major constituents of the oil. The essential oil was screened against agricultural pests. The anti-tick properties were tested on Ripicephalus e. ervertsi found on sheep, while repellency, fumigation, and contact toxicity tests were carried out with maize weevils. Except for the contact toxicity test, all other bioassays gave positive results.

Continuous Use

This mini review focuses on the ethnopharmacology, phytochemical, and biological/pharmacological activity and toxicology of the medicinal plant, Bauhinia forficata reported during 2012–2016. The results confirmed the continuous use of this plant, especially the leaves, for medicinal purposes, particularly as remedies for the treatment of diabetes and other ailments. Other new biological potential was evidenced, including anti-ulcerogenic, hypocholesterolemic, hepatoprotective and diuretic effects. Clinical and toxicological studies have advanced gradually, requiring more detailed experiments, to ensure the safe use of this plant for medication. Some new flavonoids were detected in this species, but significant differences were observed when comparing the chemical composition of its sub-species.

Shed Light

There are many motives to study alkaloids within Crassulaceae family, such as chemotaxonomic consideration of alkaloid distribution and evaluation of their biological potential. Data on alkaloids from Sedum telephium (syn. H. telephium) aroused interest for further alkaloid investigation within the genus Hylotelephium H. Ohba. Thus, the aim of this study was to investigate and characterize other plant sources of alkaloids from the same genus. An alkaloid extract (AE-HS) was isolated from fresh aerial parts of a cultivated hybrid H. spectabile x telephium. The chemical composition of AE-HS was determined by GC-MS (gas chromatography - mass spectrometry) method. Eight components were identified, which made up 91.8% of the sample. The most present component of AE-HS was g-crotonolactone (78.6%) followed by 3-methyl-2-butenal (8.6%) and (E)-coniferyl alcohol (2.8%). Nicotine was identified as the only alkaloid in the AE-HS (0.4%). Along with many non-alkaloid compounds, a previous study found six alkaloids in AE of S. telephium (~7%), suggesting differences from our results. Additionally, alkaloid distribution is limited within other genera of the family and belonging to the same genus does not mean a uniform qualitative composition. Further analyzes of AEs of Hylotelephium taxa would certainly shed light on the pattern of alkaloid distribution.
