Biological Actions

Our study compares the content in polyphenolic compounds and hypericin, in four species of Hypericum - H. perforatum L., H. maculatum Cr., H. hirsutum L., H. tetrapterum Fr. (syn. Hypericumacutum Mnch.) harvested from spontaneous flora in the north-western area of Transylvania, Romania. These species represent an important source of such compounds with different biological actions. After making the extracts, they were subjected to HPLC-SM analysis. The presence of rutoside in the largest amount (462.82 mg %) in the H. perforatum extract was observed, this containing most of the flavonoid heterosides. For the species H. maculatum, the presence in a much higher amount of the hyperoside (976.36 mg %) is characteristic compared to the other species. Quercetol is the best represented of the flavonoid aglycons, its concentration being the highest in H. hirsutum (659.66 mg %). The hypericin content ranges from 0.2171 g % in the H. tetrapterum extract, to 0.0314 g % in the methanol extract of H. maculatum.The highest antioxidant properties measured by FRAP method were recorded in the case of H. perforatum and H. maculatum.

Data for 12 crops, 1927 to 1938, have been used to examine the protein contents of Grades 1, 2, and 3 Northern drawn from the northern and north-western area, and from the central and southern area, of Western Canada. The boundary between the areas was taken as that dividing zones averaging over and under 13% protein. Grades 1, 2, and 3 Northern from the southern area averaged 14.2, 14.0, and 14.0% protein; those from the northern area averaged 12.8, 12.0, and 11.6% protein; and the average difference between zones for all three grades was 2.0%. The reasons for the increase in the spread between zones with decreasing grade are discussed. For the 12 yr. period, the average protein content of shipments of Western Canadian wheat is estimated as 13.5%. If no wheat had been shipped from the northern zone the average protein level would have been increased by about 0.5 per cent.

Previous to the voyage of the Endurance in 1914–1915, the depth and extent of the Weddell Sea were either based on or surmised from the deep-sea soundings made on the Scotia by Dr Bruce in 1903 and 1904; on Dr Otto Nordenskjöld's ship Antarctic in 1901–1902; and on the German Expedition ship Deutschland under the leadership of Lieut. Filchner in 1912–1913. The first set are confined to the eastern and north-eastern portion, and may be said to run diagonally across the mouth of the sea; the second set were made in the extreme north-western area; whilst those of the Deutschland are disposed right down the centre of the sea, and consist mainly of a south-to-north series approximately along the meridian of 43° W.

In a previous communication an account was given of the sedimentary series exposed along the eastern coast-line of the Shetlands from Rova Head to Sumburgh Head. Fossil evidence was adduced which enabled the position of these beds in the Old Red System to be fixed more definitely than had hitherto been the case; they were shown to be partly of Middle, partly of Upper Old Red Sandstone age, the base of the Rova Head Conglomerate being taken as the dividing line. Since the publication of that paper additional fossils have to be recorded. Examination of the numerous specimens of the Microbrachius from the fish-beds of Shetland fails to reveal any specific distinction between that form and Microbrachius dicki Traq. occurring in the John o' Groat's Sandstone Group, and the Eday Sandstones; it is therefore an important addition to the chain of evidence linking up the Shetland horizon with those of Orkney and the Mainland. An additional record of little stratigraphical value is that of Coccosteus (sp. indet.), a single plate of which was found by Professor W. H. Lang at a horizon slightly below the fish-bed at Shingly Geo, Dunrossness.
