The aerial parts of Scorzonera aristata Ramond ex DC., collected in the South Tyrolean Dolomites, yielded the flavonoids quercetin 3- O-glucoside, rutin, and isoorientin, and the caffeic acid derivatives chlorogenic acid, 4,5-dicaffeoyl quinic acid, and 3,5-dicaffeoyl quinic acid. Sub-aerial parts contained caffeic acid methyl ester, 3,5-dicaffeoyl quinic acid, and the triterpenes 3α-hydroxyolean-5-ene, lupeol, and magnificol. Chemosystematic implications of the isolated compounds are discussed briefly.

Many different natural materials are used in complementary medicine. Among natural products, herbal materials are used quite a lot. Centaurea rigida Willd. was used as material in this study. The antioxidant and oxidant potential of the plant was determined. The aerial parts of the plant sample were extracted with ethanol in a soxhlet device. Antioxidant and oxidant potentials were measured with Rel Assay kits. As a result of the studies, the total antioxidant value of the plant was determined as 3.522±0.166, the total oxidant value as 15.424±0.281 and the oxidative stress index as 0.440±0.020. It was determined that the plant has antioxidant potential, but its oxidant values are high. As a result, it was determined that C. rigida could be used as a natural antioxidant source.

AbstractMany natural product chemists are working to identify a wide variety of novel secondary metabolites from natural materials and are eager to avoid repeatedly discovering known compounds. Here, we developed liquid chromatography/mass spectrometry (LC/MS) data-processing protocols for assessing high-throughput spectral data from natural sources and scoring the novelty of unknown metabolites from natural products. This approach automatically produces representative MS spectra (RMSs) corresponding to single secondary metabolites in natural sources. In this study, we used the RMSs of Agrimonia pilosa roots and aerial parts as models to reveal the structural similarities of their secondary metabolites and identify novel compounds, as well as isolation of three types of nine new compounds including three pilosanidin- and four pilosanol-type molecules and two 3-hydroxy-3-methylglutaryl (HMG)-conjugated chromones. Furthermore, we devised a new scoring system, the Fresh Compound Index (FCI), which grades the novelty of single secondary metabolites from a natural material using an in-house database constructed from 466 representative medicinal plants from East Asian countries. We expect that the FCIs of RMSs in a sample will help natural product chemists to discover other compounds of interest with similar chemical scaffolds or novel compounds and will provide insights relevant to the structural diversity and novelty of secondary metabolites in natural products.

Trail Resistance

TRAIL selectively kills cancer cells without harming most normal cells. However, TRAIL resistance is a major problem for its therapeutic use. Developing a strategy to overcome resistance is crucial for the successful use of TRAIL as an antitumor agent. In our screening program of natural products that can abrogate TRAIL resistance, four germacranolides (1–4) were isolated from the aerial parts of Enhydra fluctuans. All compounds exhibited potent TRAIL-resistance overcoming activity against TRAIL-resistant human gastric adenocarcinoma (AGS) cells.

Ten guaianolides, including three previously unreported natural products, were isolated from the aerial parts of Cichorium intybus (Asteraceae), more commonly known as chicory. Two of the new compounds ( 8 and 9) were analogues of lactupicrin and 11/β,13-dihydrolactupicrin, respectively, with the C-15 oxidized to the aldehyde state. The third new natural product, which we have called mtybulide A (10), is an isomer of lactucin with the lactone closed to the C-8 oxygen rather than the C-6

AbstractThe present review gives an overview about the status of research on seasonal variation of natural products in herbs growing in or grown in Europe. Due to pronounced differences in weather patterns, papers covering plants from the Mediterranean, the temperate, and the cold climate zones are reviewed separately. Apart from trying to give an overview of the existing newer literature after the year 2000, we try to identify some repeatedly found seasonal trends and discuss some possible explanations for these trends. Moreover, some suggestions, which encompass both research bias and desirable quality standards concerning experimental designs for future studies, are given. The covered investigations are mainly focused on aerial parts and leaves. Some publications are also dealing with flowers and roots. The composition of essential oils of aromatic plants are particularly well investigated. Phenolics are the most often studied compound class, including different types of phenolic acids, flavonoids, and tannins. Additionally, some papers assess the seasonal variation of alkaloids and lipophilic compounds.

Radical Scavenging Ability

Heracleum lasiopetalum belongs to the Apiaceae family and is native to Iran. The fruits and seeds of the herb are used as spices and food additives. The genus has significant pharmacological activities. In order to study the phytochemicals of H. lasiopetalum, aerial parts of the plant were conducted to a separation process. Different chromatographic techniques were employed for the purification of its natural products. The chemical structure of the isolated metabolites was determined using spectroscopic methods such as NMR and IR as well as elemental analysis. Moreover, the essential oil composition of roots and aerial parts of the herb were characterized using GC-MS analysis. The purified compounds were elucidated as beta-sitosterol (plant steroid) and suberosin (coumarin). Identification of essential oil composition showed that 17 and 12 volatile compounds were present in the aerial parts and roots of the herb, respectively. Germacrene D, falcarinol, farnesol, and octanal were found as the major components. Findings showed that H. lasiopetalum contains important natural products such as steroids, coumarins, monoterpenoids, and sesquiterpenoids. According to its bioactive products, this herb could be considered for more applications in the cosmetics and pharmaceutical industries.
