alpha hederin/クロタネソウ属

We have previously reported the in vitro cytotoxic activity of column fraction 5 (CC-5) of an ethanolic extract of Nigella sativa seeds. In this study, the effect of CC-5 was evaluated for its in vivo antitumor activity against i.p. (intraperitoneally) implanted murine P388 leukemia and s.c.

In the present study, the preventive effect of two different concentrations of α-hederin, the active constituent of Nigella sativa, on lung inflammation and blood cytokines in ovalbumin sensitized guinea pigs was examined. Forty eight male adult guinea pigs were divided into control (C), sensitized

Many investigations have demonstrated the prophylactic effect of Nigella sativa on asthma disease. One of its active constituents is α-hederin. In the present study, the preventive effect of two different concentrations of α-hederin on tracheal responsiveness and lung inflammation in

OBJECTIVE In previous studies the therapeutic effects of Nigella sativa have been demonstrated on asthmatic animals. In the present study, the preventive effect of single dose of alpha-hederin, its active constituent, has been evaluated on lung inflammation and some inflammatory mediators in lungs

Our previous studies on active constituents of Nigella sativa have indicated that cell death induced by thymoquinone and alpha-hederin was dose- and time-dependent, in a range of four cancer cell lines. Both compounds elicited necrosis and apoptosis with a higher incidence of the latter induced by

The separate effects of alpha-hederin and thymoquinone, the two principal bioactive constituents of Nigella sativa, on four human cancer cell lines [A549 (lung carcinoma), HEp-2 (larynx epidermoid carcinoma), HT-29 (colon adenocarcinoma) and MIA PaCa-2 (pancreas carcinoma)] were investigated.

Alpha-hederin (α-HN), a pentacyclic triterpene saponin, has recently been identified as one of the active compounds of Nigella sativa, as a potential anticancer agent. However, no extensive studies on α-HN have been done as yet, as it was in the case of thymoquinone-the main ingredient of the

OBJECTIVE To investigate the chemical constituents in the seeds of Nigella glandulifera. METHODS The chemical constituents were isolated and repeatedly purified on silica gel column. They were identified and structurally elucidated by means of physio-chemical constants and spectral

Black cumin (Nigella sativa L., Ranunculaceae) is an annual herb commonly used in the Middle East, India and nowadays gaining worldwide acceptance. Historical and traditional uses are extensively documented in ancient texts and historical documents. Black cumin seeds and oil are commonly used as a

Natural product studies explore potential and interesting new compounds to discover innovative drugs. Nigella sativa (N. sativa) (Ranunculaceae) is traditionally used to treat diabetes. Flavonoids and triterpenoid mostly show anti-diabetic activity. The current study aim to identify

Hydroponically cultivated Nigella sativa L. plants treated with methyl jasmonate (MeJA) showed a twelve-fold increase in levels of the monodesmosidic triterpene saponins alpha-hederin and kalopanaxsaponin I (KsI) in the leaves. We will demonstrate that these two saponins accounted for approximately

Background: Coronaviruses are responsible for several human diseases such as the pandemic infectious disease 2019 (COVID-19) which is caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Nigella sativa (NS)

Nigella sativa (N. sativa) seed has been an important nutritional flavoring agent and natural remedy for many ailments for centuries in ancient systems of medicine, e.g. Unani, Ayurveda, Chinese and Arabic Medicines. Many active components have been isolated from N. sativa, including thymoquinone,

BACKGROUND The pharmacological properties of Nigella sativa L. are well attributed to the presence of bioactive compounds, mainly, thymoquinone (TQ), thymol (THY) and α hederin and their antioxidant effects. TQ, THY and alpha-hederin (α-hederin) provide protection to liver from injury via different

It is estimated by the World Health Organization (WHO) that most of the world's population depends on herbal medicine for their health care. Nigella sativa (N. sativa), also known as black-caraway and as "Kalonji," is a well-known seed all over the world. It is one of the most common medicinal
