GERMINATION CHARACTERISTICS OF TEDERA (BITUMINARIA BITUMINOSA VAR. BITUMINOSA)

Erybraedin C, a natural compound from the plant Bituminaria bituminosa, inhibits both the cleavage and religation activities of human topoisomerase I.

The interaction of human topoisomerase I and erybraedin C, a pterocarpan purified from the plant Bituminaria bituminosa, that was shown to have an antitumour activity, was investigated through enzymatic activity assays and molecular docking procedures. Erybraedin C is able to inhibit both the cleavage and the religation steps of the enzyme reaction. In both cases, pre-incubation of the drug wit...

Volatile constituents throughout Brassica oleracea L. Var. acephala germination.

In this work, the volatile composition of kale ( Brassica oleracea L. var. acephala) and its variation during germination were monitored during the first 9 days of seedling development by headspace solid-phase microextraction (HS-SPME) combined with gas chromatography/ion trap-mass spectrometry (GC/IT-MS). Differences were found among the materials in the distinct analyzed periods. A total of 6...

The ethnopharmacology of Madeira and Porto Santo Islands, a review.

The ethnopharmacology of Madeira and Porto Santo Islands is extremely interesting because of the cultural and biogeographic features of this region, which make it a centre of medicinal plant diversity (richness of endemic flora, geographical isolation in the Atlantic sea, crosscultural influences, and past abundance of local healers). The medicinal flora of Madeira is composed of 259 species. S...

Effect of Temperature and Light on Germination Characteristics of Japanese Morning Glory (Ipomoea nil): Determination of Cardinal Temperatures of Germination

DOR: 98.1000/2383-1251.1398.6.115.11.1.1575.1610 Extended Abstract Introduction: In recent years, Japanese morning glory has been recognized as a new weed in some soybean cultivation areas in the Province of Golestan. Japanese morning glory, an annual herbaceous plant, belongs to Convolvulaceae family. Germination is the first step in the competitiveness of a weed in an ecological niche. ...
