Resveratrol, which occurs in two isomeric forms, trans and cis, is a phytoalexin with numerous pharmacological activities, such as anti-cancer, antiviral, neuroprotective and anti-aging. Red wine is the main source of the compound and an easy way of including resveratrol in the human diet. In this study, the most popular commercial Serbian wines (red, white and ros?-type) were analyzed for their content of trans- and cis-resveratrol. The analysis was performed by HPLC with a UV detector. Prior to the injection, phenolic compounds were extracted onto a LiChrolut RP18 bonded silica cartridge. The concentration of trans-resveratrol ranged from 0.11 to 1.69 mg L-1 and cis-resveratrol from 0.12 to 1.49 mg L-1.

Background: Quercetin, one of the most beneficial flavonoids, has been included in the human diet due to its therapeutic effect on health. Recently, Quercetin is gaining scientific attraction for its multifarious activities, including anti-oxidant, anti-inflammatory, antiviral, anti-diabetic, anti-cancer, anti-arthritic, as well as function to ease some cardiovascular diseases. However, these applications of quercetin in the pharmaceutical field are limited due to its poor aqueous solubility and poor permeability. Objective: The present review summarizes various pharmacological activities of quercetin, analyses the barriers like solubility and permeability, which restrict the therapeutic efficiency of quercetin, and also discusses novel approaches to enhance aqueous solubility and permeability of quercetin for its effective clinical use. Methods: The current review information sources were peer-reviewed relevant scientific articles of recognized journals from scientific engines and databases (Scopus, Web of Science, PubMed, Science Direct, Google Scholar) using different key words related to quercetin pharmacological effects, mechanism, solubility, permeability, absorption barriers, and formulation approaches. Results: Various novel approaches, including solid dispersions, inclusion complex, pro-drugs, nanoemulsion, micelles, liposomes, SNEEDS, and microspheres, have been developed to overcome the solubility and permeability barriers for efficient quercetin delivery. Conclusion: This review revealed that the multifaceted pharmacological activities of quercetin for management of various disease are enormously dependent on the development of novel and safe drug delivery systems of quercetin.

Mucuna pruriens seeds are noted to be a natural source of L-DOPA and are also used as a substitute for the synthetic L-DOPA. In the present study; attempts are made to develop suitable method(s) for extraction of L-DOPA from the powdered seeds of Mucuna pruriens using different solvents and conditions. The Seed powder was subjected to 7 different extraction methods and Method 1 was subjected to various solvent concentrations. Some methods used de-fatting procedure, either the method was cold maceration or in high temperature. Soxhlet extraction was also used in one of the extraction methods. All the extracts were analyzed using RP-HPLC. Mobile Phase used was Water: Methanol: AcetoNitrile (100:60:40) (v/v) containing 0.2% Triethylamine, pH = 3.3 and monitored at 280 nm with variable wavelength UV detector. The extraction was best with Methanol Water mixture in a cold maceration technique and overall gives good extraction efficiency of 13.36 % L-DOPA and id the best method giving highest extraction efficiency. The De-fatting method was the 2nd best methods giving approximately 8.8% L-DOPA and Method 5 viz, heat reflux method gives 8.7% L-DOPA making it the 3rd best method. There are not many studies done for optimization of extraction technique for L-DOPA despite an extensive work is reported for isolation, identification and pharmacological activities of L-DOPA from various plant sources. Keeping this in view, present investigation was done to study the extraction efficiency of various extraction methods of L-DOPA content in seed extracts of Mucuna pruriens and compare it.

AbstractChrysin has been shown to exert several beneficial pharmacological activities. Chrysin has anti-cancer, anti-viral, anti-diabetic, neuroprotective, cardioprotective, hepatoprotective, and renoprotective as well as gastrointestinal, respiratory, reproductive, ocular, and skin protective effects through modulating signaling pathway involved in apoptosis, oxidative stress, and inflammation. In the current review, we discussed the emerging cellular and molecular mechanisms underlying therapeutic indications of chrysin in various cancers. Online databases comprising Scopus, PubMed, Embase, ProQuest, Science Direct, Web of Science, and the search engine Google Scholar were searched for available and eligible research articles. The search was conducted by using MeSH terms and keywords in title, abstract, and keywords. In conclusion, experimental studies indicated that chrysin could ameliorate cancers of the breast, gastrointestinal tract, liver and hepatocytes, bladder, male and female reproductive systems, choroid, respiratory tract, thyroid, skin, eye, brain, blood cells, leukemia, osteoblast, and lymph. However, more studies are needed to enhance the bioavailability of chrysin and evaluate this agent in clinical trial studies. Graphic abstract

Phytochemical Constituents

The study is intended to evaluate the pharmacological activities, isolation and characterization of the bioactive phytochemical constituents from the crude leaf extract of Sterculia urens Roxb. The extraction of the phytochemicals from the leaves was carried on Soxhlet extraction apparatus using solvents like hexane, ethyl acetate, methanol and water. Pharmacological activities such as DPPH free radical scavenging assay (antioxidant), α-amylase inhibition assay (antidiabetic), albumin denaturation assay (antiinflammatory), blood clot lysis method (thrombolytic) and well diffusion method (antibacterial) of the crude extracts were evaluated and then the semi-preparative HPLC analysis followed by spectral studies was carried for the purification and identification of bioactive compounds. The methanolic extract showed high DPPH radical scavenging activity, α-amylase inhibition activity and albumin denaturation inhibition activity with IC50 values of 29.51±0.11, 146.85±0.18 and 149.91±0.19 μg/mL respectively. The % clot lysis of the methanolic extract was found higher than the other extracts and all the extracts have potential inhibition on the growth of the bacterial studied. From the leaf methanolic extract, 4 phenolic compounds (2,4-dihydroxybenzoic acid, methyl 4- hydroxycinnamate, p-coumaric acid and stercurensin) and 3 phenolic compounds (gossypetin, farrerol and quercetin 5,7,3',4'-tetramethyl ether) were isolated and characterised. Based on the results observed, it can be concluded that the leaf extracts of Sterculia urens Roxb are having rich phytochemical constituents with prominent pharmacological activities.
