TL;DR: A review on the analytical methodologies, which includes the extraction methods and the analysis of bioactive compounds present in the plant extracts through the various techniques involving the applications of chromatographic techniques such as HPLC (High Performance Liquid Chromatography), TLC (Thin Layer Chromatography) and OPLC (Optimum Performance Laminar Chromatography).
Abstract: Plants are recognized in the pharmaceutical industry due to their broad spectrum of structural diversity and their wide range of pharmacological activities. The biological active compounds that are present in plants referred as phytochemicals. These phytochemicals derived from different parts of plants such as leaves, barks, seed, seed coat, flowers, roots and pulps and thereby used as sources of direct medicinal agents. Phytochemistry describes the large number of secondary metabolic compounds present in the plants. The plants are the reservoirs of naturally occurring chemical compounds and of structurally diverse bioactive molecules. The extraction of bioactive compounds from the plants and their quantitative and qualitative estimation is important for exploration of new biomolecules to be used by pharmaceutical and agrochemical industry directly or can be used as a lead molecule to synthesize more potent molecules. This review mostly highlighted on the analytical methodologies, which includes the extraction methods and the analysis of bioactive compounds present in the plant extracts through the various techniques involving the applications of chromatographic techniques such as HPLC (High Performance Liquid Chromatography), TLC (Thin Layer Chromatography), HPTLC (High Performance Thin Layer Chromatography), OPLC (Optimum Performance Laminar Chromatography), GC (Gas Chromatography), PC (Paper Chromatography), CC (Column Chromatography) and it’s detection through Fourier Transform Infra-Red spectroscopy (FTIR), Nuclear Magnetic Resonance (NMR), and Mass Spectrometry (MS).

TL;DR: Characterizing the phytochemical content and therapeutic value of two Lebanese plant species suggests a promising potential for Crataegus azarolus L and Ephedra campylopoda during treatment of diseases associated with oxidative stress, aberrant inflammatory responses or uncontrolled cell proliferation.
Abstract: Plants have long been known for their natural arsenal, serving as an important source of nutrients and therapeutic components. Since about 600,000 years ago, humans used plants as medicines. Plant medicines correspond to the preparations issued from those plants. Today, plant medicines are widely worldwide where about 80% of the world's population uses herbs as primary medicines. This medicinal value is mainly attributed to the fact that plants are rich inbioactive phytochemicals. Lebanon, due to its geographical location and important environmental characteristics, is endowed with a rich flora. Hundreds of Lebanese plants have been defined in terms of their chemical composition and medicinal value where many other species are yet to be characterized.In this study, we aimed at characterizing the phytochemical content and therapeutic value of two Lebanese plant species, Crataegus azarolus L and Ephedra campylopoda. Fresh leaves, derived from each plant species, were dissolved in three different solvents distilled water, ethanol, and methanol. The phytochemical composition of different extracts issued from the two plant species was examined using high performance liquid chromatography (HPLC) and the essential oil content was determined by gas chromatography (GC) coupled with mass spectrometry (MS). DPPH radical scavenging and Fe2+ chelating activity assays were used to assess the antioxidant potential. Anti-inflammatory potential was evaluated by measuring the secreted amounts of the pro-inflammatory mediator PGE2 using ELISA technique, as well as by assaying the mRNA levels of the pro-inflammatory cytokines (IL-α, IL-β and IL-6), chemokines (CCL3 and CCL4) and inflammation-sensitive COX-2 and iNOS using quantitative RT-PCR (qRT-PCR). XTT viability assay was carried out to determine the anti-proliferative effect of each extract. For both plant species, we observed an important phytochemical content with thealcoholic (methanol and ethanol) extracts being more rich in bioactive molecules. In parallel, the two plant species exhibited significant biological activities with the alcoholic extracts exerting important, in vitro, antioxidant, anti-inflammatory and anti-proliferative effects.Collectively, our observations suggest a promising potential for Crataegus azarolus L and Ephedra campylopoda during treatment of diseases associated with oxidative stress, aberrant inflammatory responses or uncontrolled cell proliferation. However, further in vivo characterization of these effects is indispensable.

Abstract: Although phenanthrenes are considered
to constitute a relatively
small group of natural products, discovering new phenanthrene derivatives
and evaluating their prospective biological activities have become
of great interest to many research groups worldwide. Based on 160
references, this review covers the phytochemistry and pharmacology
of 213 naturally occurring phenanthrenes that have been isolated between
2008 and 2016. More than 40% of the 450 currently known naturally
occurring phenanthrenes were identified during this period. The family
Orchidaceae is the most abundant source of these compounds, although
several new plant families and genera have been involved in the search
for phenanthrenes. The presence of certain substituent patterns may
be restricted to specific families; vinyl-substituted phenanthrenes
were reported only from Juncaceae plants, and prenylated derivatives
occur mainly in Euphorbiaceae species. Therefore, these compounds
also can serve as chemotaxonomic markers. Almost all of the newly
isolated compounds have been studied for their biological activities
(e.g., potential cytotoxic, antimicrobial, anti-inflammatory, and
antioxidant effects), and many of them showed multiple activities.
According to the accumulated data, denbinobin, with a novel mechanism
of action, has great potential as a lead compound for the development
of a new anticancer agent.
