This work studies the effects of water deficit and heat, as well as the involvement of chlororespiration and the ferredoxin-mediated cyclic pathway, on the tolerance of photosynthesis to high light intensity in Hibiscus rosa-sinensis plants. Drought and heat resulted in the down-regulation of
Partial leaf shedding induced by hydraulic failure under prolonged drought can prevent excess water consumption, resulting in delayed recovery of carbon productivity following rainfall. To understand the manner of water use of invasive species in oceanic island forests under a fluctuating water
Graded concentrations (0.1-100 mg/mL reaction mixture) of the methanolic extract of the flowers of Hibiscus rosa-sinensis Linn., its water-soluble fraction as well as compounds isolated from this fraction were tested for their inhibitory effect on alkaline phosphatase enzyme activity in vitro. Both
Many plants are known to possess antifertility activity. However, limited attempts have been made to scientifically evaluate these claims. Hibiscus rosa-sinensis flowers have been shown to possess antifertility and abortifacient activity. In this report, antiimplantation activity of water extract of
Microgeographic genetic variation in populations of a wetland macrophyte, Hibiscus moscheutos L. (Malvaceae), was investigated using allozyme polymorphism. The species is a self-compatible insect-pollinated perennial, and seeds are water dispersed (hydrochory). Six hundred plants were analyzed from
The effects of ultrasonic power, extraction time, extraction temperature, and the water-to-raw material ratio on extraction yield of crude polysaccharide from the leaf of Hibiscus rosa-sinensis (HRLP) were optimized by statistical analysis using response surface methodology. The response surface
Exposure of skin to UVB radiation is associated with skin thickening, erythema, deep wrinkles, and marked losses of elasticity, resilience, and hydration. To find effective anti-aging materials, scientists have studied not only natural nutritional sources, but also biotransformed metabolites.
A greenhouse experiment was conducted to examine the photosynthetic and physiological responses of two-year-old cuttings of Hibiscus hamabo to the drought stress (20 days) and subsequent rewatering (21 days). The results showed that after 20-day drought, all individuals were survived in spite of the
Hibiscus rosa sinensis (H rosa sinensis), a plant product, has been used for the treatment of a variety of diseases as well as to promote wound healing. The wound-healing activity of the ethanol extract of H rosa sinensis flower was determined in rats, using excision, incision, and dead space wound
The seeds from ten Hibiscus hamabo provenance families were treated with concentrated sulfuric acid for different durations (0, 10, 15, and 20 min) , and the seed germination rate, germination energy, and germination index, as well as the seed relative water adsorption rate, soluble sugar and starch
In this work, using the EPR and PAM-fluorometry methods, we have studied induction events of photosynthetic electron transport in Hibiscus rosa-sinensis leaves. The methods used are complementary, providing efficient tools for in situ monitoring of P700 redox transients and photochemical activity of
Hibiscus acetosella was shown to exert beneficial effects in humans and animal models however, the effects of this plant on DNA are unknown. The aim of this study was to determine the antigenotoxic and antimutagenic effects of H. acetosella extracts on alkylating agent methyl methanesulfonate (MMS)
Zinc toxicity in secretory cells caused a range of effects, mainly depending on metal concentration. Low concentrations activated nectary function increasing nectar secretion but secretion was greatly inhibited or stopped entirely by ongoing concentration. Water loss rate of zinc treated flower
OBJECTIVE
The purpose of this study was to evaluate the anticancer activity of 10 selected traditional Chinese medicinal plants on 4 cancer cell lines, namely MCF-7 (breast carcinoma), BALL-1 (acute lymphoblastic leukemia), Huh-7 (hepatocellular carcinoma), HeLa (cervical carcinoma) and their
Recent studies reported the detection of numerous emerging and active pharmaceutical constituents in the ground and surface water. To address these issues, the present study reported the ultrasound-assisted synthesis of zero-valent copper (Cu0) nanoparticles using Hibiscus rosa-sinensis
