BACKGROUND Although ferns are often known under collective names in Norway, e.g. blom, a substantial number of vernacular names for individual fern species are known, in particular for useful or poisonous taxa. In the past, the rhizomes (Norwegian: moldfôr) of selected species were collected for fodder. Only scattered records of such use are available from southern Norway, and the tradition's c...

ginger plant, zingiber officinale roscoe, is an important tropical plant used as spices and well known for its medicinal properties. it has a pungent and aromatic rhizome rich of zingiberen and gingerols. many secondary metabolites are known to accumulate in the plant cell culture systems. so, in this research, gingerols and zingiberene production of callus cultures were compared with regenerat...

Identification and isolation of (R(S)R(C))-S-(methylthiomethyl)cysteine-4-oxide from rhizomes of Tulbaghia violacea Harv. is reported. The structure and absolute configuration of the amino acid have been determined by NMR, MALDI-HRMS, IR, and CD spectroscopy. Its content varied in different parts of the plant (rhizomes, leaves, and stems) between 0.12 and 0.24 mg g(-1) fr. wt, being almost equa...

Kaempferia parviflora Wall. ex Baker is a medicinal plant found in the upper Northeastern regions of Thailand, which belongs to Zingiberaceae family. The present study aims to investigate the standardization parameters, to analyze chemical constituents of volatile oil by gas chromatography-mass spectrometry, and to determine the content of 5,7-dimethoxyflavone in K. parviflora rhizomes by thin-...

Miscanthus × giganteus grown in cool temperate regions of North America and Europe can exhibit severe mortality in the year after planting, and poor frost tolerance of leaves. Spartina pectinata (prairie cordgrass), a productive C4 perennial grass native to North America, has been suggested as an alternative biofuel feedstock for colder regions; however, its cold tolerance relative to M. × giga...

This study determined the role of plant and microbes in arsenite (AsIII) oxidation in the growth media and the location of AsIII oxidation and arsenate (AsV) reduction in Pteris vittata tissues. P. vittata grew in 0.10-0.27mM AsV or AsIII solution under aerated or sterile condition for 1h to 14d. Arsenic speciation was conducted in the growth media, biomass (roots, rhizomes, rachis, pinnae, and...

Curcuma rhizomes are herbal remedies commonly used in oriental medicines such as Ayurveda and traditional Chinese medicine (Shishodia et al., 2005; Xia et al., 2005). During the past twenty years, curcumin, one of the key active substances of curcuma rhizomes attracted great interests in biomedical research (Shishodia et al., 2005; Anand et al., 2007). So far, thousands of research papers have ...

INTRODUCTION The risk of drug resistance and the use of medicinal plants in malaria prevention and treatment have led to the search for new antimalarial compounds with natural origin. METHODS In the current study, six extracts with different polarity from aerial parts and rhizomes of Eremostachys macrophylla Montbr. & Auch., were screened for their antimalarial properties by cell-free β-hemat...

Objective: To evaluate the hepatoprotective potential of methanol extract of roots and rhizomes of Smilax zeylanica L on carbontetrachloride (CCl4) induced hepatotoxicity in Wistar albino rats. Methods: Hepatotoxicity was induced in Wistar albino rats of either sex by administration of CCl4 0.5 ml/kg p.o. once a day for 7 days. The methanol extract of roots and rhizomes of Smilax zeylanica L we...

Six extracts with different polarity from aerial parts and rhizomes of Eremostachys azerbaijanica Rech.f., were screened for their antimalarial properties by cell free 𝛽-hematin formation assay. Dichloromethane (DCM) extracts of both parts of plant showed significant antimalarial activities with IC50 values of 0.949 ± 0.061 mg/mL in aerial parts and 0.382 ± 0.011 mg/mL in rhizomes. Bioactivity-...
