DIVERSIDAD GENÉTICA Y MEJORAMIENTO DE PLANTAS MEDICINALES= Medicinal plants and improvement of medicinal herbs:

The genetic and chem. variability of raspberry growing wild in Poland was detd.  HPLC was applied for detn. of phenolic compds.  The RAPD anal. indicated genetic variability of investigated populations.  Chem. anal. revealed differences in the total content of flavonoids, phenolic acids and tannins in the leaves and roots.  Flavonoids, namely quercetin, hyperoside, rutin, kaempferol, and isorhamnetin derivs. (isorhamnetin-3-glucoside and isorhamnetin-3-rutinoside) were found only in the leaves.  Five phenolic acids were also identified, i.e., caffeic, chlorogenic, ellagic, rosmarinic and gentisic acids.  Roots of red raspberry were richer in phenolic acids than leaves.

ÚLTIMOS AVANCES EN LA QUÍMICA Y ACTIVIDADES BACTERIOLÓGICAS EN LAS PLANTAS MEDICINALES= Medicinal plants, last advances on chemistry and bacteria activities on the medicinal herbs


1)
Antioxidant phytochem. differences among cultivars and changes after storage have not been explored in primocane raspberries grown in a hot, dry climate.  It was hypothesized that significant differences would be detected in total phenolics and antioxidant capacity [oxygen radical absorbance capacity (ORAC)] between cultivars and over time.  'Autumn Bliss' had the highest ORAC and phenolic content, whereas 'Caroline' had the lowest ORAC and phenolic content when fresh.  Averaging all cultivars and pickings, refrigerated berries had a significantly higher total phenolic content than fresh or frozen berries, although some moisture loss occurred during std. refrigeration.  Antioxidant capacity and total phenolic content of primocane raspberries grown in hot, dry conditions vary between cultivars, on av. do not change significantly after storage, are higher later in the season, and are higher than supermarket cultivars.

2) We investigated some of the chem. properties and antioxidant capacities of 14 wild red raspberry accessions selected from northern Turkey.  In addn., the cultivars Heritage and Tulameen were included in the study to det. the variation between wild and cultivated raspberries.  Total phenolics (TP), total monomeric anthocyanins (TMA), sol. solids (TSS), individual org. acids and sugars in the fruit were examd.  Antioxidant capacity of fruits was detd. by both ferric reducing ability of plasma (FRAP) and trolox equiv. antioxidant capacity (TEAC) assays.  The fruit color and wt. were detd. as well.  The result of this study indicated that some of the wild accessions of red raspberries have higher antioxidant capacity and phytonutrient content than existing domesticated cultivars.  Moreover, significant variability was found for antioxidant capacity, TP, TMA, org. acids and sugars of wild raspberries.  Principle component anal. showed that the accessions were divided into three groups: A2, A9, A12, A14 formed the first group with high phytonutrient properties; the cultivars Heritage and Tulameen grouped together with high phytonutrients but low color values; and the rest of the accessions formed the final group.  The antioxidant capacity among samples averaged 14.6 and 14.1 mmol TE/gfw using FRAP and TEAC methods, resp.

3) The biosynthesis of the monoterpenes (-)-a-pinene, linalool, and the norisoprenoids a- and b-ionone in raspberry fruits (Rubus idaeus L.) was investigated by in vivo feeding expts. with [5,5-2H2]-mevalonic acid lactone and [5,5-2H2]-1-deoxy-D-xylulose.  The volatile compds. were extd. by stirbar sorptive extn. and analyzed using thermal desorption-multidimensional gas chromatog.-mass spectrometry (TD-enantio-MDGC-MS).  The feeding expts. demonstrate that (-)-a-pinene and (S)-linalool are exclusively synthesized via the cytosolic mevalonic acid pathway.  In contrast, 2H-labeled (R)-(E)-a-ionone and 2H-labeled (E)-b-ionone are detectable after application of d2-1-deoxy-D-xylulose and d2-mevalonic acid lactone, resp.  However, (R)-linalool reveals no incorporation of either one of the fed precursors, even though this enantiomer is detectable in the fruit tissue.

A new and distinct floricane fruiting red raspberry, Rubus idaeus L., variety is described.  The variety results from selection among a population of seedlings derived from the controlled pollination crossing of the raspberry varieties known as HR101 (not patented) and 'Willamette' (not patented).  The new variety is distinguished from others by the dwarfing nature of the plant which tends to produce many canes that do not grow more than approximately 600 mm in height.  The plant is not suited to commercial fruit production but is very suited to ornamental uses such as in the home garden and containers where it produces attractive foliage and edible raspberry fruit comparable in size to those of taller growing varieties.
