Background and objectives: Attenuated total reflectance-inferared (ATR-IR) spectra can be used as a non-invasive fingerprinting approach in quality control of herbal samples. Methods: Twenty versatile herbal samples were subjected to attenuated total reflectance-inferared (ATR-IR) spectroscopy followed by different clustering methods in order to determine by which method more reasonable classifications would be obtained. Results: All classification methods (K-means, HCA, PCA and SOM) were able to discriminate the two medicinal seeds, <em>Hyocyamus niger</em> and <em>Peganum harmala</em> from other herbal samples. Similarly, the starch samples were clustered in a reasonable method. In HCA, one cluster included three types of starch samples:<em> Zea mays</em>, <em>Oryza sativa</em> and <em>Triticum aestivum</em>. All the four classification methods were able to separate <em>Solanum tuberosum </em>starch from other starch samples. HCA and SOM, were able to classify leaf samples <em>Origanum vulgare</em> and <em>Melissa officinalis</em> belonging to Lamiaceae family, in one category. <em>Crocus sativus</em> and its adulterant <em>Carthamus tinctorius</em> flowers were identified by PCA, HCA and SOM as different categories. Conclusion: The result of this study can be utilized for identification and quality control of traditionally used medicinal plant samples in an unknown sample powder. Such data could be the basis for preparing a data bank on Iranian medicinal samples which in turn is used as a simple, fast and reliable method for characterization of herbal powders in Pharmacopoeias.

Background and objectives: Colorectal cancer is the third most common cancer and a major cause of morbidity globally. Hepatocellular carcinoma is a leading cause of death in the world. About 80% of all anticancer drugs are somehow related to natural products. One of the most important of these natural compounds is curcumin, the main component of turmeric that has a wide range of pharmacological activities. Curcumin has been found to suppress cell proliferation and decrease cell viability in various types of cancer cells; however, owing to lack of aqueous solubility, curcumin has shown reduced bioavailability in studies. Recent studies have shown that new 400<sup>th</sup> generation of dendrosome nanoparticle can increase bioavailability of curcumin and thus enhance the cytotoxic properties. The aim of this study was to determine effectiveness of curcumin alone and in combination with 400<sup>th</sup> generation dendrosome nanoparticles (DNC) on cell viability rate in SW480 and Huh7 cells. Methods: SW480 and Huh7 cells were incubated with different concentrations of curcumin and DNC (0-50μM) for 24, 48 and 72 h. Then cytotoxicity was assessed by MTT assay and IC<sub>50</sub> was determined. Results: The results suggested that the concentration-dependent inhibitory effect of DNC was stronger than curcumin on SW480 and Huh7 cells. Conclusion: The results suggest DNC as a more effective herbal anticancer agent for colorectal and hepatocellular tumors.

Background and objectives: The genus <em>Verbascum</em>, with nearly 360 species, is one of the largest members of Schrophulariacea family. In the Flora of Iran, the genus <em>Verbascum</em> is represented by 43 species among them seventeen plants are endemic. <em>Verbascum</em> species are well known in folk medicine and are widely used for therapeutic purposes. <em>Verbascum sublobatum </em>Murb. grows wildly in north of Iran. Literature review has shown that there is no report on phytochemical investigation about <em>V. Sublobatum</em> leaves. In the present study, phytochemicals of the plants have been isolated and the antioxidant activity of the extracts from leaves of <em>Verbascum sublobatum </em>Murb. has been evaluated. Methods: Dried and powdered plant were extracted with 70% methanol and then partitioned by chloroform, ethyl acetate, and buthanol. The ethyl acetae fraction showed the strongest DPPH radical scavenging activity among the three fractions and was subjected to separation and identification. The separation and purification process were performed using various chromatographic methods. Structural elucidation was carried out on the basis of FT-IR, NMR and UV data. Results: The isolated compounds which had flavonoid structure, were identified as apigenin and luteolin. Conclusion: The isolated compounds have been previously reported from other species of <em>Verbascum</em> which demonstrates the chemotaxonomic significance of the isolated compounds.

Esters of phthalates, mainly applied as plasticizer, cause several human health and environment hazards. Phthalates are widely used in pharmaceutical products, cosmetics, as well as other plastic commercial products, and can penetrate in foods, water dusts, and air leading to ingestion and inhalation exposure followed by skin absorption for human. These compounds cause serious adverse effects on human health like destroying the endocrine system, and consequently developmental alterations and reproductive changes through induction of inflammation and oxidative stress. Some phthalates are able to bio-accumulate in water and have been isolated from aquatic organisms. Mammals and birds may be influenced by these compounds through food chain. Therefore, simple and rapid method for identification and quantification of these compounds is a debate especially for developing countries. Gas Chromatography-Mass Spectroscopy has been successfully employed to determine and measure these compounds in volatile fractions of the plant or the algal materials without more essential chemical reactions. In this article, a rapid review on phthalate toxicity and related analysis methods to detect them in herbal extracts is presented.
