Fruit peels are generally underutilized byproducts of the food industry, although they valuable sources bioactive compounds. The aim this study is to evaluate a new application for three

Peucedanum ostruthium (L.) W. D. J. Koch (Apiaceae) is a worldwide perennial herb native to the mountains of central Southern Europe. The rhizome has long tradition in popular medicine, while ethnobotanical surveys have revealed local uses leaves for superficial injuries. To experimentally validate these uses, plant material was collected Gran Paradiso National Park, Aosta Valley, Italy, and were micromorphologically phytochemically characterized. Polyphenol-enriched hydroalcoholic leaf...

Himantoglossum robertianum (Loisel.) P. Delforge is a Mediterranean orchid whose propagation in vitro has been achieved, making it eligible as source of bioactive substances. Flowers were analyzed by light and SEM microscopy used to obtain polyphenol-rich, hydroalcoholic flower extract (HFE). HFE was characterized for total phenols, flavonoids proanthocyanidins, polyphenol profile RP-LC-DAD. Antioxidant assays, collagenase elastase inhibition, MTT cell motility assays on HaCaT keratinocytes...

A detailed chemical composition of Dendrobium essential oil has been only reported for a few main species. This article is the first to evaluate composition, obtained by steam distillation, five Indian species: chrysotoxum Lindl., harveyanum Rchb.f., and wardianum R.Warner (section Dendrobium), amabile (Lour.) O’Brien, chrysanthum Wall. ex Lindl. Densiflora). We investigate fresh flower GC/FID GC/MS. Several compounds are identified, with peculiar distribution in Saturated hydrocarbons...

Melanin is the main pigment of human skin, playing primary role protection from ultraviolet radiation. Alteration melanin production may lead to hyperpigmentation diseases, with both aesthetic and health consequences. Thus, suppressors melanogenesis are considered useful tools for medical cosmetic treatments. A great interest focused on natural sources, aimed at finding safe quantitatively available depigmenting substances. Lichens thought be possible sources this kind compounds, as...

Abstract Over half of angiosperms have self-incompatibility systems to avoid self-pollination and inbreeding depression. Many members Orchidaceae are self-compatible, but they may be prone negative consequences self-pollination. We investigated the effects both within-flower (autogamy) within-plant (geitonogamy) self-pollination, cross-pollination on fruit set, seed quality, germination rates in 11 related orchid taxa subtribe Orchidinae. hand-pollinated flowers measured set estimate pre-...

Mertensia maritima is a commercially interesting herb with edible leaves and flowers, characterized by oyster flavor taste. Plant propagation traditional cultivation are challenging for this species. Therefore, the main purpose of present study was to establish successful protocols aimed at ensuring plant shoot propagation, rooting in vivo acclimatization. Both micropropagation were tested, comparing vitro solid substrate jar vs. liquid culture temporary immersion system (TIS) bioreactor...

In the context of a symbiotic plant-fungus interaction study concerning Cattleya purpurata, we focused on some aspects seed morphology and biology, early stages seedling development. Seed was characterized using light scanning electron microscopy. vitro germination capability evaluated, comparing asymbiotic methods. The seeds overall comparable to that other congeneric species, showing classical adaptations related aerodynamic properties wettability seeds, but calcium oxalate druses were...

Hybridization can often lead to the formation of novel taxa which have traits that resemble either or both parental species. Determining similarity hybrid is particularly important in plant conservation, as hybrids form between rare and common may more closely a species, thereby putting taxon at further risk extinction via increased backcrossing introgression. We investigated floral (morphological chemical) orchid mycorrhizal (OrM) fungal associations endangered Orchis patens, its sister...

Due to the high demand, orchid propagation by in vitro techniques has lately increased, with an emphasis on ways improve germination and seedling development. In this work we compare efficiency of three classic media for a newly formulated medium supplemented almond milk. Our target species responded differently both supplement. However, exception Bulbophyllum plumatum that did not show statistical differences most common media, beneficial effect development growing new was observed...

Abstract Onobrychis carduchorum (Fabaceae) is a plant widely employed in Kurdish traditional medicine to cure wounds, inflammations, and other skin diseases. We could isolate ten different polyphenols from the acetone extract of this plant: 1–4 are isoflavones, having genistein skeleton; 5–7 flavanones, naringenin 8–10 prenylated dihydro-stilbenes. In particular, have been isolated, so far, only Glycyrrhiza glabra (liquorice). Many above phenols showed significant toxicity on some human...

Orchids are among the most widely distributed plants but also threatened by biotic and abiotic factors.Their interactions with specific symbiotic fungi during germination in natural environments make their propagation challenging for conservation biologists.In this study, framework of European project LIFEorchids, protocol endangered Mediterranean species Orchis patens was optimised, effect controlled constant temperature growth chambers fluctuations occurring compared.Seed viability...

Summary Ophrys apifera ( BEE ORCHID ) is illustrated here (Plate 1106). It a widespread species, occurring in southern and western Europe (absent from most of Scotland Scandinavia), extending into south‐western Asia North Africa. A detailed description provided, with notes on habitat cultivation. Given its wide distribution, it not threatened; however, collection the eastern Mediterranean for salep production may lead to decline populations region.

Summary Anacamptis pyramidalis ( pyramidal orchid ) is illustrated here. It a widespread, mostly temperate European species (absent from northern Scotland and much of Scandinavia), extending into south‐western Asia North Africa. A detailed description provided, with notes on cytology, habitat cultivation. collected in the eastern Mediterranean for salep production, but, given its wide distribution, this harvest unlikely to have an impact global conservation status.

Summary Platanthera chlorantha ( greater butterfly orchid ) is illustrated here (Plate 1102). It a widespread, temperate European and western Asian species. A detailed description provided, with notes on habitat. Given its wide distribution the diverse range of habitats where it occurs, conservation status Least Concern in Europe. occasionally available for sale, but due to cultivation requirements should be regarded as plant grown by specialists.

Introduction Petunia × hybrida and Verbena bonariensis are two herbaceous taxa with edible flowers originating from South America. Despite the well-known ornamental value of these taxa, their potential as a food source remains underexplored. Methods Therefore, in our study, P. V. obtained plants grown organically greenhouse were identified via DNA barcoding analysis investigated to characterize micromorphological features, composition nutrients, nutraceutical compounds, spontaneous emission...

Geographic isolation is one of the primary drivers speciation, but islands remain a reservoir overlooked and understudied endemic species. In this study, we collected seed micromorphological data from Orchis canariensis (Orchidaceae), declining species occurring only on Canary Islands (Spain), whose taxonomy was debated in past decades. The aim study to detect traits support delimitation by means light scanning electron microscopy. Seeds population Tenerife resulted be clavate with cell...
