Species ofPicramniagenus are used in folk medicine to treat or prevent skin disorders, but only few species have been studied for biological activity and chemical composition.P. gracilisTul. is a native species from Central and South America and although its fruits are edible, phytochemical analysis or medicinal uses of this species are not known. In the search of candidates to antileishmanial drugs, this work aimed to evaluate the antileishmanial activity ofP. gracilisTul. inin vitroandin vivostudies. Only ethanolic extract of fruits showed leishmanicidal activity. The majoritarian metabolite was5,3′-hydroxy-7,4′-dimethoxyflavanoneether that exhibited high activity againstL. (V.) panamensis(EC5017.0 + 2.8 mg/mL, 53.7 μM) and low toxicity on mammalian U-937 cells, with an index of selectivity >11.8.In vivostudies showed that the flavanone administered in solution (2 mg/kg/day) or cream (2%) induces clinical improvement and no toxicity in hamsters with CL. In conclusion, this is the first report about isolation of5,3′-hydroxy-7,4′-dimethoxyflavanoneofP. gracilisTul. The leishmanicidal activity attributed to this flavanone is also reported for the first time. Finally, thein vitroandin vivoleishmanicidal activity reported here for5,3′-hydroxy-7,4′-dimethoxyflavanoneoffers a greater prospect towards antileishmanial drug discovery and development.

Physalis peruviana calyces are used extensively in folk medicine. The crude ethanolic extract and some fractions of calyces were evaluated in order to explore antioxidant and anti-inflammatory activities. The anti-inflammatory activity was evaluated by the TPA-induced ear edema model. The antioxidant in vitro activity was measured by means of the superoxide and nitric oxide scavenging activity of the extracts and fractions. The butanolic fraction was found to be promising due to its anti-inflammatory and antioxidant activities. Therefore, a bio-assay guided approach was employed to isolate and identify rutin (1) and nicotoflorin (2) from their NMR spectroscopic and MS data. The identification of rutin in calyces of P. peruviana supports the possible use of this waste material for phytotherapeutic, nutraceutical and cosmetic preparations.

Artemisia ludoviciana Nutt. (Asteraceae) is widely used in Mexican folk medicine for treating inflammation, diabetes and painful complaints. The in vivo antinociceptive, antiinflammatory and antihyperalgesic activities of an aqueous extract (AE) of the plant were investigated using well-known animal models. AE reduced the licking time in the formalin test in healthy and NA-STZ mice; the activity was better during the inflammatory phase; accordingly, it displayed significant antiinflammatory when tested at the same doses using the carrageenan-induced oedema model. AE also produced a significant dose-dependent antinociceptive effect in the hot plate test at 100 and 316 mg/kg (p.o.). Phytochemical analysis of the non-polar fraction of AE resulted in the isolation of two major lactones [achillin (1) and dehydroleucodin (2)], which showed antiinflammatory effect, being 2 the most active at 17.7 mg/kg. A suitable analytical method was successfully developed and validated to quantify 1 and 2. Altogether, these results tend to support the medicinal uses of the plant.

Mitracarpus Scaber

Some plants have been reported to be of medicinal values and reserve some antimicrobial properties. One of such plants is Mitracarpus scaber and its effect on bacterial growth is evaluated. The study aimed at evaluating the phytochemical analyses and antimicrobial potentials of Mitracarpus scaber against aquatic bacteria including Aeromonas, Bacillus, Vibrio and Staphylococcus Spp. Leaves of Mitracarpus scaber were collected, washed and air dried and phytochemical analysis and antimicrobial investigation of ethanolic and aqueous extracts of the leaves were carried out against a panel of bacteria isolated from diseased catfish from various farms. The phytoconstituents detected include saponins, tannins, flavonoids, tarpenoids, steroids, anthraquinones and alkaloids in both aqueous and ethanolic extracts. Both aqueous and ethanolic extracts of M. scaber showed varying degree of antibacterial activities but ethanolic extract showed a higher activity against the pathogens tested. The ethanolic extract had zones of inhibition similar to that of standard antibiotics (enrofloxacin) across all tested microbes.  The lowest minimum inhibitory concentration of ethanolic extract of M. scaber was against Bacillus sp with 10mg/ml while the highest was 85mg/ml against Staphylococcus species. The results of the assays showed promising evidences that M. scaber is a potential antibacterial agent against aquatic microbes.  However, further studies are recommended to fractionate its constituents and determine the in vitro and in vivo anti-microbial activities and the exact mechanism of action of the constituents.

Datura innoxia is an important species of Solanaceae family with several purposes in folk medicine. This study intends to explore the cytotoxic effect of D. innoxia on various cancer cell proliferation. D. innoxia ethanolic extract’s effect on the progression of the cell cycle and the induction of apoptosis were investigated by flow cytometry. Further, real-time PCR was employed to confirm apoptosis initiation. In addition, active phytochemicals of D. innoxia was identified by gas chromatography–mass spectroscopy (GC-MS). The cell viability study revealed that the ethanolic extract of D. innoxia demonstrated potent cytotoxicity, with an IC50 value of 10 μg/mL against LoVo colon cancer cells. Cell cycle staining with propidium iodide revealed that D. innoxia treatment leads to cell accumulation in the sub-G1 phase. Using the Annexin V-FITC/PI assay, the ethanolic extract was found to cause a dose-dependent increase in early and late apoptosis when compared to control cells. Apoptosis as the mode of cell death was also confirmed by the increased expression of p53, bax and caspase-8, -9, and -3 along with downregulation of Bcl-2. GC-MS analysis displayed that 3,5-Dihydroxybenzoic acid (16.53%), heneicosyl formate (14.14%), 2,3-dimethyl-3-pentanol (12.89%), 2-hydroxy-4-methyl pentanoic acid (5.19%) were the main phytoconstituents. These findings conclude that D. innoxia causes cell death through apoptosis, suggesting more attention should be paid to further exploration of the active components from D. innoxia responsible for the observed activities.

Perilla frutescens (L.) Britt. (PF) is an annual herbal medicinal, aromatic, functional food and ornamental plant that belongs to the mint family, Lamiaceae. The origin of perilla traces back to East Asian countries (China, Japan, Korea, Taiwan, Vietnam and India), where it has been used as a valuable source of culinary and traditional medicinal uses. Leaves, seeds and stems of P. frutescens are used for various therapeutic applications in folk medicine. In the absence of comprehensive review regarding all aspects of perilla, thus this review aims to present an overview pertaining to the botanical drug, ethnobotany, phytochemistry and biological activity. It was found that the taxonomic classification of perilla species is quite confused, and the number of species is vague. Perilla has traditionally been prescribed to treat depression-related disease, anxiety, asthma, chest stuffiness, vomiting, cough, cold, flus, phlegm, tumour, allergy, intoxication, fever, headache, stuffy nose, constipation, abdominal pain, indigestion, analgesic, anti-abortive agent, and sedative. Until now, 271 natural molecules have been identified in perilla organs including; polyphenols, flavonoids, essential oils, triterpenes, carotenoids, phytosterols, fatty acids, tocopherols and policosanols. In addition to solvent extracts, these individual compounds (rosmarinic acid, perillaldehyde, luteolin, apigenin, tormentic acid, isoegomaketone) have attracted researchers' interest for pharmacological properties. Its bioactivity showed antioxidant, antimicrobial, anti-allergic, antidepressant, anti-inflammatory, anticancer, neuroprotection activity. Although the results are promising in preclinical studies (in vitro and in vivo) as well, clinical studies are insufficient, therefore further study needs to be done to validate its therapeutic effects and to ensure its safety and efficacy.

Conventional or synthetic drugs used in the treatment of inflammatory diseases are inadequate, it sometimes have serious side effects. So, number of herbal medicines is recommended for the treatment of inflammation that has no side effects. Hence our study focused to investigate the physicochemical, qualitative phytochemical analysis of bioactive compounds and In-vitro and In-vivo anti-inflammatory activity of Plumeria indica Linn (P. Indica) flowers extract which has boundless medicinal properties. The physicochemical evaluations carried out in terms of loss on drying, ash value, extractive values and acid insoluble ash value ect. Qualitative analysis of various phytochemical constituents was determined by the well-known test protocol available in the literature. The aqueous and ethanolic extract of P. Indica flowers was screened for in-vivo anti-inflammatory activity by carrageenan induced paw edema in rat model and in-vitro anti-inflammatory activity by human red blood cell membrane stabilization method. Phytochemical analysis revealed the presence of phenols, flavonoids, tannins, saponins, alkaloids ect. Ethanolic extract showed best in vitro anti-inflammatory activity was screened for in vivo anti-inflammatory activity at the dose level of 250 and 500mg/kg. Indomethacin at the dose level of 10 mg/kg was used as reference standard drug. Both the extracts showed a dose dependent anti-inflammatory potential which provide scientific basis for the traditional claims of P. Indica flowers as an anti-inflammatory drug.
