Curcuma is an important genus used in Traditional Medicine in the world. Due to similar morphological characters and same Sinhalese vernacular names of Curcuma species, adulteration or substitution takes place. The current study was conducted to understand the similarities in morphological and microscopic characters by analyzing data using multivariate test on five species available in Sri Lanka; C. albiflora, C. aromatic, C. longa, C. oligantha, and C. zedoaria. Whole plants of Curcuma species were collected in 2016, from wet and dry zones of Sri Lanka. Voucher specimens of the plants were authenticated from National Herbarium, Peradeniya, Sri Lanka. Morphological characters of five Curcuma species and microscopic characters of five Curcuma species using 5 observations of each plant were analyzed. An experiment was conducted as per WHO guidelines and other published data. Statistical tests were performed using Minitab 17. Multivariate test was used to determine the complex relationship among variables by simple correspondence analysis. Analyses examined the relationships between the 25 observations and the associations between variables in two dimensions...

Nature has been a source of medicinal agents since times immemorial. The importance of herbs in the management of human ailments cannot be overemphasized. Different extracts from traditional medicinal plants have been tested to identify the source of the therapeutic effects. As a result, some natural products have been approved as new antibacterial drugs. The objective of this research is to find out the potent antibacterial agents from the selected medicinal plants: Mangifera indica and Osyris lanceolata of Rupandehi, and Palpa districts of Nepal. The Bark and Leaves of the plants Mangifera indica and Osyris lanceolata respectively were subjected to extraction by maceration process using solvent methanol. Screening of antibacterial activity was done by disc diffusion method against the microorganisms Staphylococcus aureus and Escherichia coli at three different concentrations (1 mg/disc, 2 mg/disc, and 4 mg/disc). Both plants showed potent antibacterial activity. Minimum inhibitory concentration (MIC) assay was determined for the two extracts against these bacterias. The concentration 4 mg/disc of M. indica showed maximum activity against both E....

Lantana indica Roxb. (Verbenaceae) is grown as an ornamental plant in tropical and subtropical regions of the world. The plant is used to treat asthma, abdominal disorders, bilious fever, cancer, catarrhal infections, chicken pox, eczema, hypertension, malaria, measles, swelling, rheumatism, tetanus, and ulcers. Phytochemical investigation of a methanolic extract of the leaves led to isolating three new chemical constituents characterized n-heneitriacont-4-en-16β, 17β, 18β-triol (n-heneitriacontenol, 3), 6, 4′- dimethoxy- 7, 3′- dihydroxy flavone- 7- O- β-D-glucopyranoside (lantanaflavone 7-O-β-D-glucoside, 6), urs-12-en-3β-ol-28-oic acid 3β-D-glucopyranosyl-6´-octadecanoate (ursolic acid 3-O-β-D-glucosyl-6′-oleate, 8) along with five known compounds characterized as n- hexadecanyl oleate (1), n-octadecanyl oleate (2), oleanolic acid (4), ursolic acid (5) and oleanolic acid 3-O-β-D-glucopyranoside (7). The structures of all the isolated phytoconstituents have been established on the basis of spectral data analysis and chemical...

Teucrium polium L. is a member of the Lamiaceae family and is represented in the Flora of Syria by two variety: Teucrium polium var. angusti folium and Teucrium polium var. mollissimum. Teucrium polium is a wild-growing flowering plant, found abundantly in Syria, and it is used traditional medicine for it’s diuretic, antipyretic, antispasmodic, tonic, anti-inflammatory, antihypertensive, anorexic, analgesic, antibacterial and antidiabetic effects. Several reports have demonstrated a wide range of beneficial biological and pharmacological activities of the phenylethanoid, phenylpropanoid, and flavonoid components, while the furano neo-clerodane diterpenoids present in germander have been implicated in the in-vivo hepatotoxicity of this botanical. Phytochemical studies of this plant have been carried out. Aerial parts of the plant were extracted with petroleum ether at room temperature, and then extract with methanol in Soxhlet, and finally extract with aqueous methanol at room temperature successively. Fractionation of the methanol extract by column chromatography and purification by crystallization yielded three known flavonoids Cirsimartin 2, Cirsiliol 3, and Apigenin 4. The aqueous methanolic extract yielded one new...

Anxiety is an obnoxious condition of inner disorder, often accompanied by thoughts, somatic complaints, and nervous behavior. Anxiety is initiated by external stimuli. It may be as a consequence of any underline disease condition such as Parkinson’s disease, rheumatoid arthritis, or diabetes. There are different types of anxiety which are a social anxiety disorder, selective mutism, agoraphobia, specific phobia, panic attack, and separation anxiety disorder. In this study anxiolytic activity of methanolic and ethanolic extract of Leaves of Trachyspermum ammi has been determined. For this purpose methanolic and ethanolic extract of Trachyspermum ammi leaves were prepared and evaluate anxiolytic activity in-vivo on mice by using light and dark model of anxiety. Data analysis by using two way ANOVA gives highly significant results, i.e. (P<0.000) for both methanolic and ethanolic extract of Trachyspermum ammi...
