solidago ptarmicoides/carbohydrate

Polyphenolic-polysaccharide-protein complex has been isolated from flowers of Solidago canadensis L. by hot alkaline extraction procedure. Compositional analyses of S canadensis complex revealed the presence of carbohydrates (43 wt%), protein (27 wt%), phenolics (12 wt%), uronic acids (10 wt%) and

Four new bisdesmosidic saponins each containing eight carbohydrate units were isolated from Solidago canadensis. GC, GC-MS, FABMS analysis and mainly the use of 2D NMR techniques allowed their identification as bayogeninglycosides (canadensissaponins 1-4) 3-O-

Glycosides of polygalacic acid (2 beta,3 beta,16 alpha,23-tetrahydroxy-olean-12-ene-28-oic acid) is isolated from the aerial parts of Solidago virgaurea L. subsp. virgaurea, Heteropappus altaicus (Willd.) Novopokr. and Heteropappus biennis (Ldb.) Tamamsch. or produced by degradation of these genuine

Genuine saponins from Solidago virgaurea L., Heteropappus altaicus (Willd.) Novopokr., H. biennis (Ldb.) Tamamsch., and Helianthus annuus L. (Asteraceae) as well as related carbohydrate modified glycosides of polygalacic acid and echinocystic acid were investigated in view of their structure related

Derelict contaminated sites are often colonized spontaneously by plant species leading to a vegetal cover thought to limit particle dispersal and polluted water infiltration. Those plants must cope with soil pollutants through tolerance mechanisms that are not yet fully understood. Here, we focused

Triterpenoid glycosides obtained from Solidago virgaurea L. and Bellis perennis L. (Asteraceae) inhibit the growth of human-pathogenic yeasts (Candida and Cryptococcus species). First results are given of the investigations on the mode of action and the relationships between structure and activity

Genuine saponins of Solidago virgaurea L., Heteropappus altaicus (Willd.) Novopokr., Heteropappus biennis (Ldb.) Tamamsch. and Helianthus annuus L. (Asteraceae) as well as related carbohydrate modified glycosides of polygalacic acid and echinocystic acid and some commercial available triterpenoid

Dissecting complex connections between cytogenetic traits (ploidy levels) and plant invasiveness has emerged as a popular research subject in the field of invasion biology. Although recent work suggests that polyploids are more likely to be invasive than their corresponding diploids, the molecular

Third-instar larvae of the goldenrod gall fly Eurosta solidaginis (Diptera: Tephritidae) from populations in northern North America transition from freeze-susceptible to freeze-tolerant just prior to the onset of winter. While studies have documented the accumulation of carbohydrate cryoprotectants

Bagasse, corn husk, and switchgrass were pretreated with ammonia water to enhance enzymatic hydrolysis. The sample (2 g) was mixed with 1-6 mL ammonia water (25-28% ammonia) and autoclaved at 120 degreesC for 20 min. After treatment, the product was vacuum-dried to remove ammonia gas. The dried
