Morphological and flavonoid pattern variations within some Euphorbia cyparissias L. populations

The leafy spurge Euphorbia cyparissias L. is a very common and adaptive plant species in Europe. It prefers the xeroterm areas. Eleven populations of this plant were studied in Hungary at different ecological habitats: forest and road edge, swamp field and lime stone rock grass. These areas were exposed to sun to various degree and have different base stones and soil types. Populations have different phenotypes: various stem and cyma height, leaf length and number of branches. We detected two main and other flavonoid components of this plant by TLC and HPLC in different quantity. Altogether 18 flavonoid compounds were detected in the populations by HPLC with very different flavonoid patterns. Plants living at shadowy habitats were higher, they had more leafy branches, leaves and more (9-13) flavonoid constituents. Populations living at sunny areas had smaller stem and leaves, and only 4-9 flavonoid compounds. According to the different morphology and flavonoid pattern the populations were classified into ecotype groups which can be related to the studied ecological habitats. These results prove that Euphorbia cyparissias L. is a very polymorph plant species

Some phytochemical and morphophysiological characteristics of Euphorbia cyparissias L. populations

Perennial plants are able to adapt to different ecological habitats with their morphological and physiological characteristics. In this study some population of cyparissias L. were investigated. This stress tolerant species can adapt to its environment with morphological and reproductive marks. Differences were not detected in the presence of the investigated phytochemical compounds, only in their respective quantity, considering the extracts from Stem, leaf and inflorescence

Etnobotanikai kutatások Erdélyben az 1960-as évektől napjainkig

The traditional ethnobotanical knowledge about the plant usage is due to the archaic folklore system in Transylvania, underlining the importance of vari-ous applications, home treatments and special local terminology in each settle-ment. This summary represents ethnobotanical data about single regions, some plant species and varieties as monographs, and linguistic works reported in sev-eral books, book chapters and papers, in most cases in Hungarian. These valu-able data are connected to some plant beliefs and usage in the folk medicine, in construction and as household tools, food or fodder in different regions of Transylvania since 1960th years, based on traditional observations and experi-ences. These collection trips are carried out and continued nowadays, focusing on the study of new plant taxa for further laboratorical researches, too. However, the archaic knowledge of the informants has clearly decreased, therefore the con-servation, documentation and prevention of these data from disappearance has a primary importance nowadays

A review of nutritional value and putative health-effects of quince (Cydonia oblonga Mill.) fruit

Quince (Cydonia oblonga Mill.) has been long regarded to be a health-promoting fruit. Although it is mainly consumed in processed form, its relatively heat-stable polyphenolics were confirmed to be responsible for most of the beneficial effects. This review aims to show basic nutritional information on quince fruit such as carbohydrate, fibre, pectin and mineral element contents. In addition, vitamin and polyphenolic contents and composition as well as the physiological effects of quince consumption were also surveyed. Information on presumable protective effects against several diseases including inflammation, atopic dermatitis, ulcers and cancer is summarized. Potential antibacterial effects of quince polyphenolics were also considered. Polyphenolics are supposed to be responsible for the major part of beneficial health-effects, and phenolic compounds predominantly accumulate in peel. There exists a considerable extent of genetic variation in phytochemical composition among cultivars, which might be exploited in designing future breeding programs for quince improvement and opening new ways for health-related uses
