Twenty new polyoxygenated labdane diterpenoids (1-20) were isolated from the aerial parts of Leonurus macranthus. Their structures were elucidated on the basis of spectroscopic and spectrometric data (1D and 2D NMR, IR, and HRESIMS). The absolute configurations of macranthin A (1) and

The methanolic extract of Leonurus sibiricus aerial parts injected intraperitoneally at dose of 250 and 500 mg/kg showed a significant analgesic effect in acetic acid-induced writhing in mice. Moreover, when given orally to rats at dose of 200 and 400 mg/kg, it showed a significant anti-inflammatory

Seven undescribed labdane diterpenoids, japonicones A-G, were isolated from the aerial parts of Leonurus japonicus Houtt. Japonicones C-G contained two keto carbonyl groups in their structures attached to C-3 and C-7, which are rare for labdane diterpenoids. The structures and absolute

Motherwort (MW), a Korean folk medicine, has been applied to treat inflammatory disease. However, its effect on inflammatory cytokine release from mast cells is not well known. We investigated the anti- inflammatory effect of MW on the secretion of inflammatory cytokine such as tumor necrosis factor

OBJECTIVE Marrubiin and an organic extract of Leonotis leonurus were tested in vitro and in vivo for their antidiabetic and anti-inflammatory activities. METHODS INS-1 cells were cultured under normo- and hyperglycemic conditions conditions. An in vivo animal model confirmed the biological

Objectives: Two labdane diterpenoids, leojapone B and heteronone B, were isolated from Leonurus japonicus Houtt., and their biological activity were evaluated in this study. Methods:

Ten highly oxygenated diterpenoids (nine undescribed ones) were isolated from the aerial parts of Leonurus japonicus Houtt. 14,15-Dinor-labd-5,8-dien-3,13-dione was a 14,15-dinor-labdane diterpenoid possessing a C₁₈ skeleton. 7β,9α-Dihydroxy-6-oxo-labd-13-en-15,16-amide represented a rare

Leonurus cardiaca is a perennial plant indigenous to central Europe and Scandinavia, but it is also found in the area spanning temperate Russia to central Asia. It has been introduced to North America and has become established locally in the wild. Motherwort (Leonuri cardiacae herba) consists of

Bronchial asthma is believed to be provoked by the interaction between airway inflammation and remodeling. Airway remodeling is a complex and poorly-understood process, and controlling it appears key for halting the progression of asthma and other obstructive lung diseases. Plants synthesize a

BACKGROUND Leonotis leonurus L. (Lamiaceae) is used as a traditional medicine for a variety of ailments in South Africa. The diterpene marrubiin is the major product constituent in specimens of this plant occurring in South Africa. METHODS Marrubiin isolated from South African specimens of L.

Two new labdane diterpenoids, Leojaponin E (1) and F (2), together with three known compounds were isolated from the dried herb of Leonurus japonicus Houtt., Lamiaceae. Their structures were determined based on extensive spectroscopic analyses. The absolute configurations of 1 and 2 were elucidated

BACKGROUND Leonurus sibiricus L. (Lamiaceae), popularly known as motherwort, or "erva-de-macaé" or "rubim" in Brazil, is a plant used for the treatment of inflammatory conditions, but few studies have evaluated this anti-inflammatory activity or other activities that may be relevant. OBJECTIVE This

Leonurus sibiricus L. (LS) is a medicinal plant used in East Asia, Europe and the USA. LS is primarily used in the treatment of gynecological diseases, and recent studies have demonstrated that it exerts anti‑inflammatory and antioxidant effects. To the best of our knowledge, the present study

The immunomodulatory activity of Leonurus cardiaca L. polyphenol-rich extract (LCE) was tested in vitro on HUVECs to explore its potential therapeutic usefulness in the treatment of inflammatory lesions. The phytochemical composition of LCE, its antioxidant and cytotoxic activity, and the influence

Plants belonging to the genus Leonurus, also named motherwort, are traditionally used for anti-gynecological disorder in East Asia, and for sedative in Europe. Chemical investigation of the genus Leonurus not only enriched the natural products library, but also enlarged the pharmacological
