Justicidin B, an arylnaphthalene lignan, has strong cytotoxicity on chronic myeloid and chronic lymphoid leukemia cell lines. The first report of the production of justicidin B in a Linum species concerned in vitro culture of Linum austriacum. Therefore, culture characterization and presence of arylnaphthalene-type lignans in calli and plantlets of Linum tenuifolium from section Linastrum, Linu...
جنس linum از خانوادهlinaceae ، گیاهانی علفی و چندین ساله هستند که گونه زراعی این جنس از 2000 سال پیش در ایران کشت شده است. این گیاه چند منظوره و در صنایع غذایی، دارویی، بهداشتی و صنعتی کاربرد فراوان دارد. ریشه گونه های وحشی یا خودرو این جنس دارای یک نوع لیگنان مفیدی بنام پدوفیلوتوکسین است که لیگنان مذکور به عنوان ماده اولیه در دارو های ضد سرطان استفاده می شود. در پژوهش حاضر، ابتدا جوانه زنی چند...
Linum album Ky. ex Boiss.، یکی از گونههای انحصاری در ایران است که ترکیبهای لیگنانی مهمی را ازجمله پودوفیلوتوکسین (PTOX) تولید میکند. این ترکیب پیشساز سه نوع داروی مهم ضدسرطان به نامهای تنیپوساید، اتوپوساید و اتوپوفوز میباشد. سنتز شیمیایی این ترکیبها بسیار پیچیده است و از نظر تجاری تولید آن مقرون بهصرفه نیست. در افزایش سنتز پودوفیلوتوکسین از راهبردهای گوناگونی مانند تغییر رژیم غذایی، بکا...
Background and objectives: To date, thousands of secondary metabolites have been isolated from plants and microorganisms and there is an unprecedented attention towards potential biomedical applications of natural compounds. In this study, cytotoxic properties of methanol extracts of Stachys obtusicrena, Aristolochia olivieri, Linum album, Dionysia sawyeri, Ajuga chamaecist...
A qualified estimate for pretreatment of the macroalgae Chaetomorpha linum for ethanol production was given, based on the experience of pretreatment of land-based biomass. C. linum was subjected to hydrothermal pretreatment (HTT), wet oxidation (WO), steam explosion (STEX), plasma-assisted pretreatment (PAP) and ball milling (BM), to determine effects of the pretreatment methods on the conversi...
BACKGROUND Flax (Linum usitatissimum) seeds are increasingly used in bread and as laxatives. Hypersensitivity to linseeds has been infrequently described, and we report a case of anaphylaxis induced by linseed ingestion in a 39-year-old woman. METHODS AND RESULTS The clinical course, as well as positive skin prick tests and histamine release tests performed with linseed extracts, suggested a ...
The aim of current study was to isolate and evaluate the starch from Chenopodium album (LP) and Chenopodium album (LS) varieties for its physicochemical, particle size analysis, and textural properties. The starch isolated from C. album (LP) and C. album (LS) showed yield values of 37.59 and 47.30%, while amylose content of the mentioned varieties was found to be 16.75 and 19.11%, respectively....
Chenopodium album L. ssp. album is a common plant species worldwide, especially in humid areas. Sun exposure after oral intake of the plant can lead to sunburn-like rashes owing to its furocoumarin content. In this article, we reported nine patients who developed dermatitis with edema, erythema and necrosis on the face and dorsum of the hands. Each was exposed to sunlight after eating selemez (...
Understanding the interactions between the hemiparasite Santalum album L. and its hosts has theoretical and practical significance in sandalwood plantations. In a pot study, we tested the effects of two non-N2-fixing (Bischofia polycarpa (Levl.) Airy Shaw and Dracontomelon duperreranum Pierre) and two N2-fixing hosts (Acacia confusa Merr. and Dalbergia odorifera T. Chen) on the growth character...
