Four compounds β-sitosterol, β-sitosterol-3-O-β-d-glucopyranoside, ursolic acid and 4′,5,6-trihydroxy-3′, 7-dimethoxyflavone were characterized from the dichloromethane extract of the aerial parts ofSatureja khuzistanica(Lamiaceae), a native medicinal plant growing in Iran, on the basis of spectral analysis and comparing with the data in literature. The natural occurrence of these compounds can be conclusive for the chemotaxonomic characterization of the genusSatureja.

Spilarctia Obliqua

Blepharispermum subsessile DC. (Asteraceae) is a less explored folklore medicinal plant of India. It is found in the moist deciduous forests of Odisha, Madhya Pradesh, Chhattisgarh, Karnataka and Maharastra etc. It is locally known as Rasnajhadi in Odisha. The whole plant is used as Rasna, a potent Ayurvedic drug. Ethnomedicinally it is used for the treatment of diarrhea, skin diseases, eye troubles, backache and rheumatism, menstrual disorder, common cold and rhinitis. Reports suggest its use as a wormicidal and as tonic. The rhizome has an aromatic odour and is used in havan samagri. Its pharmacological activities include anti-microbial activity, oviposition deterent activity against potato tuber moth, anti-fertility, anti-implantation activity and anti-feedant activity against larvae of Spilarctia obliqua. Many different chromenes were isolated from the aerial parts and rhizomes of B. subsessile such as Desmethyl isoencecalin, 8-methoxy-2, 2-dimethyl chromene, desmethylisoencecalin, 5-hydroxy-6-acetyl-2-hydroxymethyl-2-methyl chromene and (-)-artemesinol. Besides chromenes the plant contains 1.2% essential oil, carvacrol, Ursolic acid acetate and β-sitosterol. The present work aims at presenting a comprehensive of the plant such as its botany, ethnomedicinal uses, chemical constituents, pharmacognostic and pharmacological uses. The information reported in this work contributes scientifically to recognizing the importance of Blepharispermum subsessile as a target in the search for new biotechnological investments.

Objective: This investigation involves the extraction, isolation, and characterization of chemical constituents from a Barringtonia family plant, Barringtonia asiatica followed by Antibacterial, cytotoxicity and evaluation of its antioxidant principles. Methods: The dried stem-bark powders were subjected to sequential soaking with polar and nonpolar solvents and extraction using rota-vap. Dichloromethane extract reveals the presence of significant amount of phytochemicals. The dichloromethane extract was subjected to isolation using column chromatographic analysis with solvents such as, dichloromethane, chloroform, hexane, ethyl acetate and methanol. Further, the isolated compound was subjected to thin layer chromatography technique and spectral analysis such as infrared, 1H-NMR, 13C-NMR, FT-IR, and mass spectroscopy. The antibacterial using agar disc method. Results: The compound was isolated in hexane: ethyl acetate (9:1) and dichloromethane: ethyl acetate in the solvent system in the ratio of 9:1 and 7:3, respectively using column chromatographic technique. On the basis of phytochemical, chromatographic, and spectral analysis, the isolated compounds were identified as Nerolidiol and Heneicosane. Conclusion: This compound was isolated for the first time from the stem-bark of Barringtonia asiatica. The in vitro antioxidant assay of isolated compounds has shown a dose-dependent increase in free radical scavenging activity using DPPH, the antibacterial and artemia salina cytotoxicity testing showed a significant result. The chromatographic separation led to the isolation of Nerolidiol (1) and Heneicosane (2). Their structures were determined by 1H-NMR, 13CNMR, IR and MS data analysis as well as by comparison of their data with the published values.

Important Medicinal Plant

Barleria cristata is an important medicinal plant of Bangladesh. Many compounds of diverse biological activities were isolated from different Barleria species, including irridoids, flavonoids and phenylethanoid derivatives in addition to other groups of chemical constituents. This paper presents the chemical investigation of the whole plants of B.cristata. Classic phytochemical investigation of organic extracts of the whole plants of B. cristata together with spectroscopic methods led to the isolation and characterization of 4-hydroxy-trans-cinnamate derivatives (1-3) and a triterpene, namely oleanolic acid (4).

The Galium verum herb, (Rubiaceae family) is well represented in the spontaneous Romanian flora. She is one of the most used plants in traditional medicine. Our research aimed to investigate the chemical volatile profile in fresh, dried and essential oil of Gallium verum using SPME and hydrodistillation techniques, followed by GC-MS analysis. Characterization of volatile compounds composition by SPME �GC-MS technique presented din this paper is the first study on fresh and dried of Galium verum plant to our knowledge. Galium verum fresh flower floral bouquet is given by monoterpenes (73,5%), sesquiterpenes (10,16%), esters (10,26%) and others(5.87%). The floral bouquet of Gallium verum dried flower, contains mainly: aldehydes (35.48%) monoterpenes (35.48%), alcohols (11.96%), sesquiterpenes, (3.71%), esters (3.14%) and others (10.11%). Sixty components were identified in the galium essential oil.
