Objective: Plant-derived bioactive molecules are providing infinite opportunities for new drug development as they possess a wide range of actions against diseases with lesser side effects. The present study is made to analyze the qualitative phytochemicals and to evaluate in vitro antiproliferative and anti-inflammatory potentials of leaf extracts of Thespesia populnea. Methods: T. populnea leaf extracts were prepared sequentially according to the increasing polarity of the solvents, i.e., petroleum ether, chloroform, ethyl acetate, and methanol. Qualitative phytochemical analysis was performed to identify the chemical constituents of the extracts, and antiproliferative properties were evaluated against different cell lines using the 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide assay. Bovine serum albumin anti-denaturation assay was done to identify the anti-inflammatory activity.Results: Phytochemical analysis of the extracts revealed the presence of alkaloids, terpenoids, glycosides, tannins, flavonoids, and phenolics. The chloroform extract (CHFE) of T. populnea has a dose-dependent antiproliferative effect against acute T-cell leukemia (Jurkat E6-1), prostate Grade IV adenocarcinoma (PC-3), mouse fibroblast (L-929), and monkey kidney normal (Vero) cells. Their inhibitory concentration 50% (IC50) values were found to be 35.73±0.94 μg/ml for Jurkat E6-1, 60.79±1.84 μg/ml for PC-3, 60.88±1.45 μg/ml for L-929, and 83.482±2.05 μg/ml for Vero, respectively. CHFE also displayed the anti-inflammatory potential.Conclusion: The chloroform leaf extract of T. populnea possesses potent antiproliferative and anti-inflammatory activity. These properties present in leaf extract may be explained by the presence of biologically active constituents.

AbstractThe leaves of Piliostigma thonningii are used in traditional medicine in Benin to treat inflammatory skin diseases and infections. So far, pharmacological studies of the anti-inflammatory and anti-infective effects of phytochemically characterized extracts of P. thonningii have been very limited. Therefore, we investigated the in vitro anti-inflammatory and antimicrobial effect of P. thonningii leaf extracts and analyzed the phytochemical composition of extracts of different polarities (water, 50% ethanol, and n-hexane). Quercetin-3-O-rhamnoside was confirmed as the main flavonoid in the polar extracts. GC-MS analysis identified 20 constituents of the aqueous extract and 28 lipophilic compounds of the n-hexane extract by comparison with authentic standards and spectral library data. The aqueous P. thonningii leaf extract inhibited the IL-8 and IL-6 secretion in TNF-α-stimulated HaCaT cells in a concentration-dependent manner with IC50 values of 74 µg/mL for IL-8 and 89 µg/mL for IL-6. However, an inhibitory effect of the identified quercetin-3-O-rhamnoside and its aglycone, quercetin, on the release of IL-8 and IL-6 could not be demonstrated. In the antimicrobial screening, inhibition zones for a 50% EtOH leaf extract of P. thonningii were found for Staphylococcus epidermidis, Staphylococcus aureus, methicillin-resistant Staphylococcus aureus, and Escherichia coli. For none of the microbial strains, however, the MIC was below 500 µg/mL, so that the antibacterial activity must be classified as low. As a result, our investigations primarily support the ethnomedical use of P. thonningii leaf extracts in topical inflammatory conditions. Further studies are required to identify the compounds responsible for the in vitro anti-inflammatory effects.

Plants from the genus Sanguisorba have been treated as medicinal ingredients for over 2000 years. This paper reviews advances in the botanical, phytochemical and pharmacological studies of the genus. To date, more than 120 chemical constituents have been isolated and identified from these plants, especially from S. officinalis and S. minor. Among these compounds, triterpenoids, phenols and flavonoids are the primary biologically active constituents. Triterpenoids can be used as quality control markers to determine the quality of medicinal materials and their preparations. In vivo and in vitro studies have shown that plants from the genus Sanguisorba exhibit a wide range of pharmacological properties, including hemostatic, antibacterial, antitumor, neuroprotective and hypoglycemic activities. In Chinese medical practice, many drugs (e.g., tablets and powders) that contain S. officinalis roots have been used to treat leukopenia, hemorrhaging and burns. However, there is still a multitude of Sanguisorba species that have garnered little or no attention. Indeed, there are few reports concerning the clinical use and toxic effects of these plants. Further attention should be focused on the study of these species in order to gather information on their respective toxicology data, any relevant quality-control measures, and the clinical value of the crude extracts, active compounds, and bioactive metabolites from Genus Sanguisorba.

Thrombotic disorders like myocardial and cerebral infarction are fatal blood clotting related diseases. Synthetic therapeutics used in such disorders has serious adverse effects, so there is a need to investigate some more safe natural thrombolytic agents. Present study is a preliminary work towards such endeavors. During this study analysis of thrombolytic activity and anti-inflammatory activity of Thespesia populnea leaf extract using a simple and quick in vitro clot lysis assay was performed. Various concentrations of leaf extract i.e. 200μg/ml; 400μg/ml and 600μg/ml were tested at various time intervals including; 24, 48 and 72 hours duration of incubation at 37°C for observing maximum clot lysis. The result findings indicated that concentrations of leaf extract enhanced the percentage of clot lysis in dose dependent manner along with the incubation time factor. However; streptokinase SK a reference standard and water were used as a positive and negative control showed clot lysis maximum 96.35% and 35.22% in 72 hours of incubation respectively. Alcohol extract of whole plant of Thespesia populnea (Family: Malvaceae) was assessed for its anti-inflammatory activity by in vitro methods. In vitro anti-inflammatory activity was evaluated using albumin denaturation assay at different concentrations. Diclofenac sodium was used as standard drug. The results showed that Thespesia populnea alcohol extract at a concentration range of 400-1600μl significantly protects from protein denaturation.

Garcinia mangostana L. is medicinal plant. Its fruit, the mangosteen contains many bioactive xanthones. This study investigates the potential of organic leaf extracts of G. mangostana grown in Ivory Coast. We tested two organic leaf extracts: G. mangostana aqueous ethanolic leaf extract (ethanol: water, 80:20 v/v) (GMLE) and dichloromethane leaf extract (GMLD). We measured total phenolic and total Flavonoids. We analysed the in vitro anti-inflammatory, anti-radical and anti-proliferative activities of leaf extracts. Ethanol leaf extract showed a considerable amount of phenolic content (328.78±34.32 mg GAE/g) and moderate flavonoids content (43.60±1.48 mg QE/g), Dichloromethane extract had low values of phenolic (70.31±4.55 mg GAE/g) and flavonoids (8.49±0.69 mg QE/g). However, GMLD extract gave a significant anti-inflammatory activity (IC50=152.79±3.34 µg/mL), comparable to the standard drug diclofenac sodium (IC50=142.30±1.22 µg/mL), contrary to GMLE extract (IC50=652.33±12.23 µg/mL). The radical scavenging assay showed a very significant ability of ethanol leaf extract to reduce the DPPH radical (IC50=33.40±0.67 µg/mL) compared to references molecules such as Trolox (IC50=43.72±0.31 µg/mL) and acid ascorbic (IC50=27.20±0.17 µg/mL), dichloromethane extract results showed lowest activity (IC50 = 580.00±23.03 µg/mL). All the organic leaf extracts of G. mangostana had moderate anti-proliferative activity on L20B, RD and VS cell lines studied with IC50 values ranging from 110.89 ±4.82 µg/mL to 860.60±25.78 µg/mL). Our results prove the high potential of the G. mangostana leave extracts as anti-inflammatory and anti-oxidative stress drugs. However, further studies are to determine and validate all the medicinal properties of G. mangostana leaves extracts.

Rhizome Buds

This study aimed to establish a rapid in vitro plant regeneration method from rhizome buds of Kaempferia parviflora to obtain the valuable secondary metabolites with antioxidant and enzyme inhibition properties. The disinfection effect of silver oxide nanoparticles (AgO NPs) on rhizome and effects of plant growth regulators on shoot multiplication and subsequent rooting were investigated. Surface sterilization of rhizome buds with sodium hypochlorite was insufficient to control contamination. However, immersing rhizome buds in 100 mg L−1 AgO NPs for 60 min eliminated contamination without affecting the survival of explants. The number of shoots (12.2) produced per rhizome bud was higher in Murashige and Skoog (MS) medium containing 8 µM of 6-Benzyladenine (6-BA) and 0.5 µM of Thidiazuron (TDZ) than other treatments. The highest number of roots (24), with a mean root length of 7.8 cm and the maximum shoot length (9.8 cm), were obtained on medium MS with 2 µM of Indole-3-butyric acid (IBA). A survival rate of 98% was attained when plantlets of K. parviflora were acclimatized in a growth room. Liquid chromatography with tandem mass spectrometry (LC-MS/MS) was used to determine the chemical profile of K. parviflora leaf extracts. Results showed that several biologically active flavonoids reported in rhizomes were also present in leaf tissues of both in vitro cultured and ex vitro (greenhouse-grown) plantlets of K. parviflora. We found 40 and 36 compounds in in vitro cultured and ex vitro grown leaf samples, respectively. Greenhouse leaves exhibited more potent antioxidant activities than leaves from in vitro cultures. A higher acetylcholinesterase inhibitory ability was obtained for greenhouse leaves (1.07 mg/mL). However, leaves from in vitro cultures exhibited stronger butyrylcholinesterase inhibitory abilities. These results suggest that leaves of K. parviflora, as major byproducts of black ginger cultivation, could be used as valuable alternative sources for extracting bioactive compounds.

A method was developed for identification and quantification of polyphenols in the leaves ofXimenia caffrausing HPLC/UV/MS. Based on analyzing the MS and UV data and in comparison to the authentic standards, a total of 10 polyphenols were identified and quantified, including gallic acid, catechin, quercetin, kaempferol, and their derivatives. The total content of these compounds was found to be approximately 19.45 mg/g in the leaf and the most abundant is quercetin-rutinoside (9.08 mg/g). The total phenolic content as measured by Folin-Ciocalteu assay was 261.87 ± 7.11 mg GAE/g and the total antioxidant capacity as measuredin vitrowas 1.46 ± 0.01 mmol Trolox/g. The antiproliferative effect of the leaf extract was measured by MTS assay with IC50value of 239.0 ± 44.5 μg/mL. Cell-based assays show that the leaf extract inhibits the mRNA expression of proinflammatory genes (IL-6, iNOS, and TNF-α) by using RT-qPCR, implying its anti-inflammatory effects. It was further demonstrated that the underlying therapeutic mechanism involves the suppression of NF-κB, a shared pathway between cell death and inflammation.
