Moso bamboo can rapidly complete its growth in both height and diameter within only 35-40 days after shoot emergence. However, the underlying mechanism for this "explosive growth" remains poorly understood. We investigated the dynamics of non-structural carbohydrates (NSCs) in shoots and attached mature bamboos over a 20-month period. The results showed that Moso bamboos rapidly completed their...

Alpinia officinarum has been confirmed to possess bioactivities against some pests. In this work, a sample was obtained from A. officinarum rhizomes by supercritical fluid CO₂ extraction (SFE). According to GC-MS analysis, the main chemical components for SFE-sample included benzylacetone (26.77%), 1,7-diphenyl-5-hydroxy-3-heptanone (17.78%), guaiacylacetone (10.03%) and benzenepropanal (7.42%)...

The concentration of three metals, zinc, copper and chromium in roots, rhizomes, stems and leaves of Phragmites australis (common reed) and Scirpus maritimus, and in the corresponding sediment and water samples from Lia industrial area (Qazvin, Iran) were investigated to determine difference in distribution among plant organs. Data were collected at during 1-year period. Results showed that met...

BACKGROUND AND AIMS Dryopteris crassirhizoma is a semi-evergreen fern growing on the floor of deciduous forests. The present study aimed to clarify the photosynthetic and storage functions of overwintering leaves in this species. METHODS A 2-year experiment with defoliation and shading of overwintering leaves was conducted. Photosynthetic light response was measured in early spring (for overw...

Dioscorea quinqueloba has been used for food substances, as well as in herbal medicines for allergic diseases such as asthma. This study aimed to investigate the anti-atopic dermatitis (AD) effects of the total extract of D. quinqueloba rhizomes and active fractionson murine oxazolone- and 2,4-dinitrochlorobenzene-induced models of AD. Specific AD symptoms, such as erythema, ear swelling, and e...

Wild berries of the genus Vaccinium have become increasingly popular in human health promotion due to their nutritional and medicinal properties. Some striking divergence of opinion about the content of triterpenoids in these plants still exists, meanwhile, this very large class of natural isoprenoids exhibits a wide range of biological activities and hence is of growing research interest. An i...

Six new and fourteen known sesquiterpenoids of diverse types were isolated from the rhizomes Acorus calamus.

The implementation of community service aims to increase the knowledge and skills participants in processing rhizomes into a fresh healthy drink, rhizome types are believed have benefits efficacy help improve health. Improving can be done by providing training through demonstrations mentoring giving opportunity try making drinks made from rhizomes. this activity was attended PKK members Sidorej...

An investigation was carried out to reveal the changes in the concentration of soluble carbohydrates under tuber dormancy in food yam (Dioscorea esculenta) tubers and in an economically important spice cum medicinal plant turmeric (Curcuma longa) rhizomes under storage. Harvested, fully matured tubers of yam and rhizomes of turmeric were stored in wooden boxes under the conditions of 28 ? 2?C t...

White turmeric has underground stems that develop rhizomes. It been used as an Eastern traditional herb for a long time. As with many other monocotyledons, the growth of white is mainly due to presence primary thickening meristem. Currently, study meristem, radial growth, and accumulation secondary material essential oil in rhizomes, including turmeric, still limited. In this study, we observed...
