Polysaccharide (DOPA) from the stem of D. officinale, as well as two fractions (DOPA-1 and DOPA-2) of it, were isolated and purified by DEAE cellulose-52 and Sephacryl S-300 chromatography, and their structural characteristics and bioactivities were investigated. The average molecular weights of DOPA-1 and DOPA-2 were 394 kDa and 362 kDa, respectively. They were mainly composed of d-mannose, d-...

BACKGROUND Nasturtium officinale is a traditional herb that is used for diuresis. OBJECTIVES The aim of this study is to determine the effects of hydrophilic extract of Nasturtium officinale on ethylene glycol-induced renal stone in male Wistar rats. MATERIALS AND METHODS In this study 32 male Wistar rats were randomly divided in six groups and studied during 30 days. Two groups of negative...

Is physiological performance a suitable proxy of fitness in plants? Although, several studies have been conducted to measure some fitness-related traits and physiological performance, direct assessments are seldom found in the literature. Here, we assessed the physiology-fitness relationship using second-generation individuals of the invasive plant species Taraxacum officinale from 17 localitie...

BACKGROUND A disruption of the balance between the water content of the stratum corneum (SC) and skin surface lipids may lead to the clinical manifestation of dryness of skin in patients with atopic dermatitis (AD). OBJECTIVE To determine whether supplementation of gromwell (Lithospermum erythrorhizon), one of herbs used in East Asia in remedies for various abnormal skin conditions, may impro...

In the present review, we give a short introduction into the history, philosophy and traditional diagnosis and therapy of Kampo, which has its origins in traditional Chinese medicine. The main focus is on pharmacogenomics of natural products derived from Kampo medicinal plants, with special emphasis on cancer treatment. One of these natural products with profound cytotoxicity against tumor cell...

Pigmented naphthoquinone derivatives of shikonin are produced at specific times and in specific cells of Lithospermum erythrorhizon roots. Normal pigment development is limited to root hairs and root border cells in hairy roots grown on "noninducing" medium, whereas induction of additional pigment production by abiotic (CuSO4) or biotic (fungal elicitor) factors increases the amount of total pi...

Growth-promoting Sphingomonas paucimobilis ZJSH1, associated with Dendrobium officinale, a traditional Chinese medicinal plant, was characterized. At 90 days post-inoculation, strain ZJSH1 significantly promoted the growth of D. officinale seedlings, with increases of stems by 8.6% and fresh weight by 7.5%. Interestingly, the polysaccharide content extracted from the inoculated seedlings was 0....

Wild plants are important in terms of human nutrition and folk medicine in Turkey. Especially the ones collected from rural areas and sold in the market are rich sources of dietary fiber important for human health. In this study, the dietary fiber contents of 13 different plants consumed frequently were determined by enzymatic-gravimetric method. The lowest amounts of insoluble fiber was found ...
