This study aimed to determine the effect of growth regulators addition on cuttings from several types croton plants. was designed using a factorial Randomized Block Design (RBD) consisting 2 factors. The first factor is type puring which consists golok kuning (P1), emping (P2), raja (P3), jet (P4), (P5), cokwe (P6). second without (Zo), Rootone-F (Z1) and coconut water (Z2). results showed that...

(cocarcinogenic) materials labeled A and C from the seeds of Croton tiglium L. were summarized (10, 11). The chemical constitution of a polyhydroxyphenolic ester, m.p. 96°C, obtained by the catalytic hydrogenation of a biologically active fraction and referred to as croton resin, was also described (10). The present report concerns long-term biologic testing of the active materials A and C, th...

Clinical and experimental studies have consistently incriminated the medicinal plant germander (Teucrium chamaedrys L.) in epidemic and sporadic cases of liver diseases. The sacaca (Croton cajucara Benth), a common plant in Brazilian Amazon region also comes being incriminated in similar clinical cases. Of both plants were isolated diterpenoid coumpounds with similar chemical structures. Key-wo...

Charles River mice were painted once with dimethylbenz(a)anthracene (tumor initiation), followed by repeated applications of croton oil (tumor promotion). The i.v. injection of Bacillus Calmette-Guérin(BCG) 3 weeks prior to the initiation of croton oil treatment reduced the incidence and rate of appearance of both benign and malignant skin tumors. After 50 applications of croton oil, (2/week f...

A total of 30 chloroform and methanol extracts from the following endemic Soqotran plants Acridocarpus socotranus Olive, Boswellia socotranao Balf.fil, Boswellia elongata Balf. fil., Caralluma socotrana N. Br, Cephalocroton socotranus Balf.f, Croton socotranus Balf. fil.., Dendrosicycos socotrana Balf.f., Dorstenia gigas Schweinf. ex Balf. fil., Eureiandra balfourii Cogn. & Balf. fil., Kalancho...

The genus Croton belongs to the family Euphorbiaceae and comprises well over 1300 species growing as trees, shrubs, and herbs in tropical and subtropical regions of both hemispheres [1]. One of its species is Croton sparsiflorus (syn. C. bonplandianus) which is a shrub growing in sandy clay soil in Asia and South America [2]. It is used as a potent hypotensive agent [3] and for the treatment of...

Four nutraceuticals, sugar beet roots, cucumber fruits, New Zealand spinach leaves, and turmeric rhizomes, were evaluated for their comparative effectiveness against dimethylbenz[a]anthracene (DMBA)-initiated and croton oil-promoted skin tumors. Three different protocols were used. The most effective protocol (Protocol 2) is the topical application of the nutraceuticals 1 h before croton oil. T...

The objective of this study was to evaluate the larvicidal activity of essential oil aqueous solutions (hydrolates) obtained by steam distillation of stalks and leaves of Croton argyrophylloides, Croton nepetaefolius, Croton sonderianus and Croton zehntneri against Aedes aegypti larvae. Twenty-five larvae of third instar were placed in plastic beckers, containing the hydrolates (50 mL), in a fo...

Henna (Lawsonia inermis) inhibited inflammatory responses triggered by croton oil in mice ears and skin. Topical application of 0.5 or 1 mg henna extract (HE) to mice ears prior to application of 0.8 mg croton oil inhibited edema significantly (P < 0.02). The average weight of inflammated ear punches decreased by 64 and 87 %. Application of HE (5 or 10 mg) reduced, significantly (P < 0.05), Hyp...
