<p><em>Carica pubescens Lenne &amp; K. Koch is a tropical species that adapt to the plateau environment and low temperatures. In East Java, the plant is found in Cangar and Bromo region. Morphological, chemical content, and analysis of protein banding pattern on C. pubescens has been done, but more on the analysis of active compounds for pharmaceutical raw materials and its accumulation in the body of the plant has not been widely studied. Saponins on C. pubescens potential as a raw material of natural medicine in the treatment of Diabetes Mellitus (DM). This study aims to determine the content of saponin in leaf and petiole of C. pubescens in terms of absorbance values. Saponins were analyzed by qualitative form the foam test, color test, Thin Layer Chromatography (TLC) analytical and preparative. Quantitative test in the form of UV-Vis spectrophotometry results preparative TLC. This research was done at the Laboratory of Department of Biology and Chemistry UIN Maulana Malik Ibrahim Malang. The results showed that the leaf and petiole of C. pubescens positive for the saponins with the formation of stable foam for 60 seconds at 1.5 cm - 1.7 cm. The third positive samples containing saponins triterpene the ring test produces a brownish color. Isolation saponin by TLC shows the best ratio of eluent chloroform: methanol: water (14: 6: 1) compounds can be separated perfectly. Saponin absorbance values obtained three samples as follows: petiole samples from the region Cangar amounted to 0.852, leaf samples from the region Cangar amounted to 0.686, and leaf samples from Bromo region amounted to 0,629.

Introduced livestock may indirectly affect bird species by decreasing vegetation structure and affecting the selection of nesting sites. This is especially true for birds that use shrubs as the raw material for nest construction or for nest placement. Nesting in inadequate supporting structures or the use of inadequate raw material for nest building may increase nest vulnerability (e.g. increasing structure weakness, falling and nest exposure to predation). Accordingly, bird species show a great variation in the selectivity of nesting sites and the raw material they use. Furnariidae family members exhibit an extraordinary diversity in nest placement and structure, which allows them to survive in different arid environments. I report here on a study of nest site selection of two common furnariid species, Leptasthenura aegithaloides and Pseudoseisura gutturalis, across a grazing gradient composed by nine independent paddocks within the same arid habitat. These species use large closed-nests (&gt;40 cm long) built with thorny branches, placed on spiny shrubs. I measured nest abundance and supporting plants characteristics, vegetation structure, browsing intensity and compared the plants selected by the birds with the surrounding vegetation. These bird species used only few plant species for nest building and location. Livestock significantly reduced vegetation cover of the species used to build and place the nests, affecting nest site selection and reducing nest abundance. As livestock density increased, both species selected aggregated plants and the tallest plants for nesting, which may increase nest exposure. Therefore, livestock may indirectly affect nest-site selection of birds ultimately affecting their nesting ecology. This work illustrates how domestic livestock, through decreasing plant cover, may affect native biota with consequences on key species within an ecosystem.

Floral morpho-anatomy of the Milla complex genera (Themidaceae) was studied with the aim to confirm the occurrence of a gynophore in Dandya, to determine if there are anatomical characters that allow to distinguish Dandya from the rest of genera of the complex (Behria, Bessera, Jaimehintonia, Milla, and Petronymphe), and to understand their evolution. Floral buds of ten species of the Milla complex were studied through the standard paraffin microtechnique. The results demonstrated the presence of a gynophore without pith in Dandya, while the other genera have a gynophore with pith. In addition, Dandya differs from the other genera of the complex by a closed-stigma with external papillae, nectary cavities of horned-shape with tabular epidermal cells, and filaments with 4-strata of parenchyma cells. Behria and Bessera share characters such as connated stamens and an ovary with the external epidermis papillose. Attributes like gynophore with pith, percentage of adnnation between ovary and floral tube of 20-30%, stigma with an open ending, and nectary cavities with discoidal shape are probably ancestral conditions in the Milla complex, from which transformation of character states occurred mostly in Dandya.

Skin diseases are numerous and a frequently occurring health problem affecting all ages from the neonates to the elderly and cause harm in number of ways. Maintaining healthy skin is important for a healthy body. Many people may develop skin diseases that affect the skin, including cancer, herpes and cellulitis. Some wild plants and their parts are frequently used to treat these diseases. The use of plants is as old as the mankind. Natural treatment is cheap and claimed to be safe. It is also suitable raw material for production of new synthetic agents. A review of some plants for the treatment of skin diseases is provided that summarizes the recent studies. Natural drugs from the plants are gaining popularity because of several advantages such as often having fewer side-effects, better patient tolerance, being relatively less expensive and acceptable due to a long history of use. Besides herbal medicines provide rational means for the treatment of many diseases that are obstinate and incurable in other systems of medicine. For these reasons several plants have been investigated for treatment of skin diseases ranging from itching to skin cancer. So far 31 plants have been reported to be effective in various skin diseases during the past 17 years (1995-2012) of research work, which are mentioned below.

The World

Since thousands years back approximately around 900 BC, medicinal plants are considered as a source of many biomolecules with therapeutic potential. Herbal medicines are considered as safer, better, physiologically compatible and costeffective. The oldest evidence of medicinal and aromatic plants depicts that with the emergence of human civilization, plants have been considered as the main source to heal and cure various serious ailments. It has been proven that the secondary metabolites e.g. alkaloid, glycosides, flavonoides, steroids etc present in the medicinal plants possesses ability to prevent occurrence of some of the diseases, means medicinal plants acts as a “preventive medicine”. Medicinal plants have a paramount importance and a great interest due to its pharmaceutical, cosmetic and nutritional values. Some plants are also considered as an important source of nutrition and are known to have a variety of compounds with potential therapeutic properties. India is the principal repository of large number of medicinal and aromatic plants or we can say India is one of the rich mega-biodiversity countries of the world. Medicinal plants are “backbone” of traditional medicinal system (TMS). Crude drugs are usually dried parts of medicinal and aromatic plants (MAPs) such as roots, stems, wood, bark, seeds, fruits, flowers, leaves, rhizomes, whole plant etc. that form the essential raw material for the production of medicines in various systems of Ayurveda, Siddha, Unani, Tibatian, Tribal and Homeopathy. According to the survey of the World Health Organization (WHO), about 80% of the world population are using herbs and other traditional medicines for their primary healthcare and have established three kinds of herbal medicines: raw plant material, processed plant material, and herbal products. Now days, variety of available herbs are used throughout the world and they continue to promote good health. As the benefits from medicinal and aromatic plants are recognized, these plants will have a special role for humans in the future. The present review on medicinal and aromatic plants revealed similar combination of studies.

Studies on the leaf epidermal characters and petiole anatomy of four species of Citrus L. viz., C. limon (L.) Burm., C. paradisi Macf., C. reticulata Blanco and C. sinensis (L.) Osbeck were carried out to establish and document their foliar anatomical characters with the aim of separating them from the modified varieties been cultivated globally. Leaf epidermal features that revealed close relationship among these taxa include hypostomatic condition, stomata shape and type, presence of secretory cavity on the adaxial surface, and polygonal shape of epidermal cells. The absence of secretory cavity on the abaxial surface separates C. limon and C. sinensis from others. Petiole anatomy revealed that the outline is flat without ribs in C. sinensis, convex with short ribs in C. reticulata, convex with long ribs in C. paradisi while in C. limon it is circular without ribs. Presence of trichomes and crystals distinguishes C. paradisi from the rest.DOI: http://dx.doi.org/10.3329/bjpt.v19i1.10938Bangladesh J. Plant Taxon. 19(1): 25-31, 2012 (June)

This work aims to characterise the morphology and anatomy of roots, stems and leaves of Calolisianthus species (Gentianaceae – Helieae) to assist in the taxonomy and understanding of some adaptive responses to high luminosity, prolonged water deficit and nutritional stress in their environment. Samples of Calolisianthus speciosus and C. pendulus were collected in campo rupestre (rocky land) and samples of C. amplissimus were collected in cerrado (savanna) areas in southeastern Brazil. The roots have a cortex with Arum-type arbuscular mycorrhizae. The three species have winged and square stems and in Calolisianthus amplissimus the stem is hollow. Calolisianthus pendulus and C. speciosus have a pair of conspicuous extrafloral nectaries at the leaf base, which are absent in C. amplissimus. Calolisianthus pendulus has a dorsiventral mesophyll and a round leaf margin with parenchymatic cells. Calolisianthus amplissimus has a homogeneous mesophyll and a leaf margin with collenchyma. Calolisianthus speciosus leaves have a homogeneous mesophyll and a margin with sclerenchyma and collenchyma. Our results demonstrate that some anatomical characters are useful for the identification of Calolisianthus species and might be used to elucidate evolutionary relationships among Calolisianthus and their adaptive responses.

Aim. The purpose of this work was to determine the dose of g- and X-ray pre-sowing irradiation of seeds of Hypericum perforatum L., causing an increase in biomass and the accumulation of flavonoids in medicinal raw materials. Methods. X-ray and g-irradiation of seeds, biometric methods, flavonoids extraction, quantification of flavonoid content in extracts using spectrophotometry, qualitative and semi-quantitative analysis of extracts using high-performance liquid chromatography (HPLC), common statistical methods for processing and analysis of data. Results. It was shown that acute X-ray pre-sowing irradiation of H. perforatum seeds at a dose of 20 Gy leads to an increase in the crop of medicinal raw material without losing its pharmaceutical value. Irradiation also increases concentration of quercetin, routine, hyperoside in herbal medicines, grown from seeds, that was chronically irradiated with g-radiation in a total dose of 1 Gy. The HPLC analysis of extracts confirmed that the qualitative composition of ethanol extracts of H. perforatum did not change due to the effect of irradiation on the seeds. Conclusions. The obtained results confirm the possibility of application of pre-sowing irradiation of seeds of H. perforatum in the range of 1–35 Gy in order to increase its productivity and increase the pharmaceutical value of the medicinal raw material. Keywords: Hypericum perforatum L., ionizing irradiation, productivity, flavonoids.
