Podophyllotoxins represent an important and unique position among natural products. They serve as the starting material for the semi-synthetic anticancer drugs etopside and teniposide, so considerable attention has focused on the availability of these aryltetralin lignans. Linum is one of the genera, with some reports on the presence of podophyllotoxin and related compounds, such as L. album, L...

In present study, biochemical compositions (ash, lipid and protein) of five different macroalgae ((Green Macroalgae-GMA (Chaetomorpha linum Caulerpa prolifera), Red Macroalgae-RMA (Pterocladiella capi-lacea), Brown Macroalgae-BMA (Sargassum vulgare Ericaria amentacea)) Angiosperm/Seagrass (Hal-ophila stipulacea) collected from Iskenderun Bay were investigated. The differences observed between s...

Two species of the genus Dynoides Barnard, 1914 (D. crenulatus Carvacho and Haasmann, 1984; D. saldanai Carvacho and Haasmann, 1984) not reported since their description were rediscovered during an intensive sampling program in the intertidal and shallow subtidal of the Mexican Pacific. Both species are abundant in the area and inhabit among the algae Jania adherens Lamouroux, 1816, Amphiroa mi...

The percentage of podophyllotoxin (PTOX) and its congener lignans were measured by HPLC in Linum mucronatum ssp. mucronatum (Linaceae) fresh plant organs. The highest amounts of PTOX (0.595 +/- 0.060% g/g dry wt) and 6-methoxypodophyllotoxin (MPTOX) (1.491 +/- 0.125% g/g dry wt) were found in the plant sexual organs. Whereas, the highest levels of beta-peltatin, 5'-demethoxy-MPTOX and yatein we...

linum persicum is an endangered plant native to iran, from linaceae family. phytochemical analysis has shown that l. persicum in vitro cultures contain podophyllotoxin (ptox), the pharmacological precursor for anticancer drugs such as etoposide, etopophos, and teniposide. shoot culture of l. persicum was established from callus cultures in ms medium containing ga3. a study was designed to inves...

background: linum album, a herbaceous and medicinal plant, has been shown to accumulate anti-tumor podophyllotoxin (ptox) and related lignans. objective: in this study, we have verified the time-course of cell growth, lignan production in cells treated with chitosan and chitin oligomers. to study mechanism of chitosan and chitin oligomers action, expression of phenylalanine ammonio-lyase (pal),...

The selected parts of four medicinal plants, Achillea millefolium, Hibiscus rosasinensis, Linum usitatissimum and Pluchea lanceolata were extracted in absolute methanol to determine their analgesic activity. Analgesic activity was assessed on intact mice by tail flick latency via the tail immersion method. The analgesic activities of these plant extracts were compared with acetylsalicylic a...
