  • The present communication attempts to evaluate the physicochemical and preliminary phytochemical studies on the fruit of Terminalia chebula Retz. Combretaceae family. Haritaki is one of the most celebrated herbs in the Indian traditional medicine system, Ayurveda. Terminalia chebula is known to exhibit different properties like anticancer, anti-inflammatory, anti-protozoal, antimicrobial, antioxidant, hepato and renal protective activities, and in the management of metabolic syndrome. As there is no detailed standardisation work reported on fruit, the physicochemical parameters, preliminary phytochemical constants, heavy metals, analysis are carried out. The phytochemical screening indicated the presence Tannin, Alkaloid, Phenol, Carbohydrate, Steroids, Protein and Resin compounds in CO2 extract of Haritaki. The present investigation will helpful in assessing the quality and purity of a crude drug. Thus, the study provides facts that CO2 extract of Haritaki contains medicinally important bioactive phytochemical compounds which justifies the use of plant species as conventional medicine for treatment of many diseases.

  • Twelve species of Ipomoea were investigated for allelopathic behavior. Seed extracts of I. quamoclit, I. nil and I. pes-tigridis showed significant allelopathy over germination of other seeds. Investigation on seed extracts of I. quamoclit, revealed the presence of several phytochemical components viz., n-triacontanol, sitosterol, stigmasterol, ${\alpha}-amyrin$, taraxerone, taraxerol, erythrodiol, cucurbitacin-G. Seed fat of twelve species were also analyzed.

  • Phytochemical study of the methanolic extract of Flaveria trinervia (Asteraceae) leaves has led to the isolation of three constituents characterised as 3,5,7,4' tetrahydroxy-6-methoxy flavone (6-methoxy kaempferol), oleanolic acid and ${\beta}-sitosterol-{\beta}-D-glucoside$. The identities of the compounds were confirmed by the physical and spectroscopic data and by comparison with authentic samples.

  • Phytochemical investigation of the aerial parts of Conyza discoridis (L.) Desf. resulted in the isolation of the new sesquiterpene dilactone ester vernomenin-6-(2-hydroxymethyl)-acrylate (4) and two known sesquiterpene dilactones vernolepin (1) and vernomenin (3). Two known flavonols, 3-O-methylquercetin (2) and transilin (3-O-methylquercetin 7-O-${\beta}$-D-glucopyranoside) (5), were also identified. The structures were determined utilizing physical, chemical and spectral methods.

  • The utility of Lepidium sativum Linn (Garden cress) as a medicinal plant has increased many fold over a period of time. A survey of literature relating to the medicinal uses of L.sativum reveals it to be one of the widely used medicinal plants. It finds place in folklore medicine, Ayurveda, Unani and other indigenous systems of medicine. Following a large number of claims on the wide range of traditional medicinal properties of the plant, considerable efforts have been made to verify its efficacy as a curative agent through pharmacological investigations and clinical trials. In this article, a comprehensive account of the traditional uses, phytochemical investigation and therapeutic potential of Lepidium sativum is presented.

  • Hexane, ethyl acetate and methanol extracts of whole plant of Boerhavia diffusa were screened for phytochemical and biological activities. Qualitative phytochemical screening via colorimetric method and the quantitative estimation of phenolic and flavonoid content were performed. Antioxidant assay using DPPH scavenging method was studied. Antimicrobial screening of plant extracts was done by cup diffusion technique. Cytotoxic activity of B. diffusa was studied by brine shrimp bioassay and anthelminthic activity was evaluated in vitro in Pheretima posthuma. This study revealed B. diffusa as a source of various phyto-constituents such as alkaloids, glycosides, saponins, tannins, carbohydrates, cardiac glycosides, flavonoids and terpenoids. Quantitative estimation of total phenol was found to be maximum in BEE i.e. $29.73{\pm}0.88$, BME $19.8{\pm}2.02$ and in BHE $9.15{\pm}0.304mgGAE/g$. Similarly, the total flavonoid content was found to be $17.44{\pm}0.75$ in BEE, $14.43{\pm}0.23$ in BHE and 3.678 mg QE/g in BME. Ethyl acetate extract showed its antibacterial activity against all tested pathogens except Escherichia coli whereas Staphylococcus aureus and Salmonella Typhi were resistant to methanol and hexane extract. The zone of inhibition (ZOI) of ethyl acetate extract against S. Typhi and B. cereus was found to be 18 mm and 14 mm respectively. The MIC value of BEE in S. Typhi was $3.125{\mu}g/ml$ and in B. cereus was $12.5{\mu}g/ml$. The preliminary screening of anticancer property of B. diffusa i.e. BSLT in methanol was found to be $165.19{\mu}g/ml$. B. diffusa was also found to contain anthelmintic property. The study helped in further exploration of medicinal properties of B. diffusa by phytochemical screening and biological activities paving the path for study and investigation in this plant.

  • A phytochemical investigation of Spergularia marina (L.) Griseb. growing in Egypt, has been carried out, which resulted in the isolation of seven compounds from the different extracts of the plant namely; ${\beta}$-sitosterol glucoside, tricin (1) dihydroferulic acid (2), vanillic acid (3), 4-hydroxybenzoic acid (4), uracil (5) and 8-hydroxy cuminoic acid (6) Structure elucidation of the isolated compounds was carried out using different spectroscopic techniques. This is the first report for the isolation of these compounds from genus Spergularia. Furthermore, 8-Hydroxy cuminoic acid and uracil were isolated for the first time from family Caryophyllaceae. The chemical composition of the volatile components present in the petroleum ether extract of Spergularia marina (L.) Griseb. using combined gas chromatography-mass spectrometry (GC-MS) is reported here for the first time. Of the 97 components present, 59 were identified including three sulfur containing compounds which represented about 1.8% of the volatiles of the total petroleum ether extract. This prompted us to study and report its possible antimicrobial activity. In addition, the antibacterial and antifungal screening of different extracts of Spergularia marina (L.) Griseb. as well as some isolates have been performed using agar diffusion method.
