Chemical composition and biological potential of plants from the genusBauhinia

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.

Human And Animal Diseases

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.

Medicinal plants have been used since time immemorial to fight against diseases. The biological activities of these plants may be due to the presence of bioactive compounds such as essential oils. The aim of this study was to determine the chemical composition of three Yemen medicinal plants, and e evaluate their antibacterial and antioxidant activities. The chemical composition of essential oils was determined using gas chromatography–mass spectrometry (GC–MS) analysis. The antibacterial effect was evaluated against pathogenic bacterial strains using the micro-platoon method and the antioxidant activity was estimated by DPPH (2,2-diphenyl-1-picrylhydrazyl) scanning radical assay. Essential oils (EOs) are rich in phenolic compound. Carvotanacetone is the main compound of Pulicaria jaubertii (PJ) essential oil (82.35%) and β-maaliene (64.94%) is the major compound of Plectranthus montanus Benth (PMB) essential oil, while, Tarchonanthus camphoratus (TC) essential oil possesses several main compounds such as fenchol (14.5%), α-pinene (12.43%), and α-terpineol (8.58%). Essential oils of PJ and PMB showed remarkable antibacterial effect against Staphylococcus aureus (minimum inhibitory concentration, MIC = 0.25% [v/v]), and PJEO against Escherichia coli (MIC = 0.25%[v/v]); the lowestMBC (minimum bactericidal concentration) values was obtained with PJEO against Staphylococcus aureus (CMI = 0.25% [v/v]). TCEO interestingly showed capacity while scanning the DPPH radical (6.32 mg E Trolox). These findings showed the biological potential of Yemeni aromatic medicinal plants as antibacterial and antioxidant agents. However, further investigations are needed to determine the antibacterial and antioxidant mechanisms of these oils.

Phytochemical Studies

Background: The Himalayan region has been reported as rich accumulation of natural wealth, particularly of aromatic and medicinal plants. Indian Ajuga species (Ajuga brachystemon, Ajuga integrifolia, Ajuga macrosperma and Ajuga parviflora) belonging to Lamiaceae family have been reported from different parts of Uttarakhand. Phytochemical studies revealed presence of various bioactive compounds including neo-clerodane diterpenoids, steroids, phytoecdysteroids, sphingolipids, triterpenoids, flavonoids, fatty acids, iridoids, triglycerides, withanolides, phenylethanoid glycosides and quinols. Modern pharmacological activities of Ajuga species including anti-inflammatory, anti plasmodial activity, anti-platelet activity, antioxidant activity, analgesic assay, anti diabetic activity, antifungal activity, insecticidal activity and cytotoxity have been published by various researchers. Objective: The present study is aimed to explore chemical composition, pharmacological and biological activities of Ajuga species as worked out by researchers and scientific community. Due to excessive use of Ajuga species it needs to be conserved and requires important measures for its conservation. Methods: The analysis of essential oils and plant extract has been reported through solvent extraction, steam distillation method, GC-MS analysis and HPLC. Results: Literature survey revealed reports of Ajuga L. to be used against various ailments such as stomach-ache, dermatitis, malaria, snake-bite, ear-ache, arthritis, bleeding, wounds, asthma, pneumonia, respiratory problems, fever, dysentery, and joint pain. Conclusion: The detailed description would be helpful in future studies. Recent biotechnological approaches have been reported useful to conserve A. bracteosa due to over exploitation for research purpose whereas A. brachystemon and A. macrosperma have been reported rarely in the wild.
