Hypericum Perforatum L

The small mountainous country of Armenia has a rich flora of ca. 3600 species of vascular plants, which makes about half of entire Caucasian flora, distributed across desert and semi-desert, steppe, forest and alpine landscape. Anthropogenic threats to this biodiversity such as overpopulation, deforestation and urbanization have simultaneously hindered research and increased the need for it. Of the ca. 500 species in the Armenian flora with a record of medicinal and/or economic use, ca. 50 species are used in the folk medicine and include both wild-collected (Crataegus sp., Hypericum perforatum, Artemisia absinthium) and cultivated (Chamomilla recutita, Mentha piperita, Crocus sativus) species (1). Only limited information on the genetic biodiversity, population location, structure and size, and conservation status of most of these species is, however, at this time available. During 2007-2009, field studies were conducted to re-locate populations of wild Hypericum perforatum L. (common St. Johnswort, Hypericaceae) on the basis of historical (i.e. herbarium voucher, (2)) records, and to discover new populations. The plants habitat and phenological characteristics were estimated growing in different populations. GPS map of population distribution was created and its overall sizes were assessed. According to historical records this species had been widely distributed in the south regions of Armenia, however almost half of the populations no longer existed in the cited locations. However, 2 new populations were loacated in the south east regions. Evidence that the abundance and distributional range of H. perforatum is expanding in the north region was collected. This research provided baseline data that can be used for the development of further ex situ and in vitro strategies to conserve unique genotypes of this important medicinal and culinary species in Armenia.

Anthropogenic Threats

Armenia has a strong interest in examining the biodiversity of native plant species and assessing their conservation status. Anthropogenic threats to this biodiversity such as overpopulation, deforestation and urbanization have simultaneously hindered research and increased the need for it. Only limited information on the genetic biodiversity, population location, structure and size, and conservation status of most of these species is, however, at this time available. During 2006-2009, field studies were conducted to re-locate populations of wild Melissa officinalis L. on the basis of historical (i.e. herbarium voucher) records, and to discover new populations. The growth, phenological and habitat characteristics of the plant, and overall populations size were assessed. GPS map of present and past population distribution were created. This research provided baseline data that can be used for the development of further ex situ and in vitro strategies to conserve unique genotypes, as well as to assess the sustainability of wild populations with regard to the IUCN Red Book Criteria, of this important medicinal and culinary species in Armenia.

Botanical Exploration

Cibodas Botanic Gardens (CBG) shall keep performing botanical exploration and ex situ conservation as part of the effort to rescue tropical montane rainforest plants, which tend to decrease in their natural habitat. Pasir Banteng and Pasir Pogor, Mount Gede Pangrango, were selected due to the potential threat and limited information on plants collected from these sites. The objectives of this study were to collect valuable plants, which have a conservation value and explore their potential usefulness. The study has begun by establishing a list of collectible plants. Then, the field activities were conducted by a plant collection explorative method along the hiking route, from 750 to 1,500 m asl, low-mid mountain as height as CBG, with no specific sampling point (found and collected). These plants have field treatment, were delivered to CBG, and would later be maintained in the garden. The study has obtained 31 species collected from Pasir Banteng and 20 species from Pasir Pogor. There were 35 families, with Orchidaceae being the most collectible. Some crucial findings were nine species included as least concern (LC) and a species as endangered (EN), based on their conservation status. At least six new species were identified as the garden enrichment of the CBG. In addition, at least fifteen species have potential utilization as construction materials, 29 species as ornamental plants, twelve species as medicinal plants, and some plants possessing multi-utilization. The results were significant in adding the collection’s richness and enhancing the conservation value of the plants conserved by CBG. It was also contributed to describing the plant species information of these sites. Keywords: botanical exploration, ex-situ, Pasir Banteng, Pasir Pogor, plant conservation

Crocus Sativus L

As plantas medicinais têm sido amplamente empregadas em formulações para diversas indicações terapêuticas. Algumas espécies têm sido estudadas para o tratamento de transtornos psíquicos como a depressão, dentre elas estão Rhodiola rosea L., Crocus sativus L. e Hypericum perforoatum L. A procura de terapias à base de plantas medicinais tem aumentado, o que denota o crescente aumento da relevância desta área. Este artigo possui objetivo de identificar a atividade das espécies em destaque como alternativas naturais no tratamento da depressão através de uma revisão de literatura envolvendo artigos entre 2010 e 2020 retirados da plataforma Pubmed, Scielo e Lilacs. Das espécies em estudo utilizadas para o tratamento alternativo da depressão, três estão em maior evidencia, destas sendo: o Hypericum perforatum L., também conhecida como Erva de São João; Rhodiola rosea L., para estados de depressão em adultos, há alguns estudos em animais e humanos que sugerem uma putativa ação antidepressiva; e o Crocus sativus L., sendo uma das especiarias mais caras do mundo, devido ao seu cultivo e forma como é colhido. Conclui-se que as espécies estudadas possuem extensa possibilidade de inserção no tratamento da depressão, seja em adolescente, adultos, idosos e até mesmo mulheres amamentando ou em depressão pós-menopausa. Assim, espera-se que tais resultados contribuam com o direcionamento de novos estudos sobre as espécies em questão, orientando pesquisas em outras áreas que possam ainda não terem sido exploradas bem como outros compostos extraídos que possam se mostrar promissores para a comunidade científica como alternativa terapêutica.

Induction Of Apoptosis

This study was carried out to test the possibility of hexavalent chromium administration through drinking water to induce the structural damage in rat�s adrenal glands and the possibility of Hypericum perforatum extract to faith against chromium aggression. Chromium induced cellular stress was determined by the expression level assessment of the Bcl2 genes family, known to modulate the apoptotic pathway. Obtained results showed that exposure to chromium altered adrenal glands morphology, by induction of apoptosis. When Hypericum perforatum extract was administered expression level of Bcl2 genes and histological lesions in adrenal glands were significantly reduced.
