Angelica keiskei Koidzumi (A. keiskei), as a Japanese edible herbal plant, enjoys a variety of biological activities due to the presence of numerous active compounds, especially flavonoids. This study aims for the optimization of ultrasound-assisted extraction (UAE) for flavonoids in
This study was performed to examine the feeding effects of Angelica keiskei Koidz (AK) and its processed products on serum, liver, and body fat content and the expression of antioxidant genes in rats fed a high fat diet. AK and its processed products were added at 3-5% to a high fat diet and fed to
Epidemiological studies indicate that consumption of green-yellow vegetables rich in chlorophyll, vitamin C, vitamin E, and carotenoids reduce the risk of cancer. We sought to examine the antigenotoxic and antioxidant properties of chlorophyll-rich methanol extracts of Angelica keiskei, Oenanthe
Angelica keiskei Koidzumi, or ashitaba, is a popular botanical medicine in Japan containing diverse bioactive components including prenylated chalcones, linear and angular coumarins, and flavanones. This review provides an overview of the current knowledge of ashitaba metabolites and their
OBJECTIVE
Angelica keiskei is a green leafy vegetable rich in plant pigment phytochemicals such as flavonoids and carotenoids. This study examined bioavailability of flavonoids and carotenoids in Angelica keiskei and the alteration of the antioxidant performance in vivo.
METHODS
Absorption kinetics
In our effort to find new whitening agents, we evaluated the effects of representative chalcones [4-hydroxyderricin (1), xanthoangelol (2), xanthoangelol H (3), deoxyxanthoangelol H (4), and deoxydihydroxanthoangelol H (5)] contained in the stem of Angelica keiskei on tyrosinase and melanin
Neuroblastoma is the most common solid tumor in children. Despite aggressive chemotherapy, the prognosis of patients with advanced neuroblastoma is still very poor. Our recent study showed that xanthoangelol, a major chalcone constituent of the stem exudates of Angelica keiskei, induced
The folk medicine Angelica keiskei (Ashitaba) exhibits antitumor, antioxidant and antidiabetic activities and it has recently attracted attention as a health food. Ashitaba is thought to have antithrombotic properties, but this has not yet been scientifically proven. The elevation of plasma
Angelica keiskei has been shown to exhibit antitumor, antioxidant, and antidiabetic activities, and the fresh leaves and dry powder are used for health food. In spite of several beneficial effects, however, the molecular mechanism or mechanisms behind anti-inflammatory activities of A. keiskei
Alcohol induces oxidative stress and inflammatory response, which can lead to hepatitis and cirrhosis. Previous studies reported that the extracts of Angelica keiskei Koidzumi (AKE) have antioxidant and anti-inflammatory properties, suggesting that AKE could improve abnormalities associated with
Oxidative stress is involved in the pathogenesis of Helicobacter pylori-associated gastric ulceration and carcinogenesis. The oxidant-sensitive transcription factor, nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB), regulates expression of inflammatory mediators such as interferon
Recently, gradual decline in human sperm production has become a serious worldwide concern because it leads to increased rates of infertility. Endocrine disrupters, lifestyle changes, and varicocele, all of which elevate testicular temperature, are thought to be the main causes of this decline. The

Angelica keiskei contains many bioactive components with anti-oxidative and anti-inflammatory effects. It is also effective for the treatment of diabetes mellitus, hypertension, and arteriosclerosis, but the relationships between these effects and the active components in the herb have Propolis collected on Jeju Island, Korea, contains characteristic components not present in propolis from other regions. Hence, the plant origin of the propolis from Jeju Island can be expected to be a novel plant. To identify the plant origin of this propolis, first we observed honeybee behavior,
