Croton oblongifolius Roxb. (Euphorbiaceae) is a weed available all over in the agricultural fields of West Bengal villages. Traditionally this plant is used as wound healing drug in the Bengal villages. As there is less number of scientific information present, an attempt has been taken to search some important phytoconstituents and their amount which may act as marker compounds. Simultaneously...

The isolation of chemically pure tumor-promoting agents from croton oil in this laboratory facilitated the exploration of a number of areas concerning their mode of action and the role of tumor-promoting agents in chemical carcinogenesis. Our recent studies have centered on the mode of action of these phorbol esters on cellular and intracellular membranes. The use of tumor-promoting agents in t...

The material was scraped off an arrow head removed from a wounded man. It was a moist earthy-looking material. An oleaginous resinous body was extracted which was soluble in alcohol (90 per cent.) and dilute acetic acid, also in ether and in chloroform, but insoluble in water. It gave the " croton oil reaction" on the tongue and in the pharynx. A little rubbed on the skin of forearm raised a cr...

The objective of this paper was to study the extraction methods of tannin constituents from Semen Cuscutae and their anti-papilloma effects. Single factor test and orthogonal design methods were used to determine the optimal extraction method; the mouse skin papilloma model induced by DMBA/croton oil was established, which was a classic two-stage carcinogenesis model being used to observe and e...

The present work evaluated the germinability and vigor of Croton urucurana seeds. 1) Seeds were sorted by color (caramel, gray and black) and were subjected to seven different pre-germination treatments followed by incubation at 20ºC, 25°C or 20/30°C. 2) Seeds were stored in cold chambers or at room temperature for up to 300 days and were subsequently incubated at 20/30ºC in a germination chamb...

A new clerodane diterpene derivative named crotonoligaketone was obtained from the stem bark of Croton oligandrum along with eight known compounds including crotonadiol, imbricatadiol, crotonzambefuran B, 7-acetoxytrachiloban-18-oic acid, 3-O-acetylaleuritolic acid, lupeol, beta-sitosterol, and stigmasterol. The structures of the isolated compounds were established on the basis of their spectra...

PURPOSE To evaluate the hepatic effect of Croton cajucara Benth (sacaca) herbal extract in rats. METHODS 60 Wistar rats (Rattus novergicus albinus) were used, weighing between 250 and 350 g. The animals were distributed randomically in 2 groups: GS - animals which received daily 0,1 ml/ 100 g of sacaca herbal extract through gavage, and GA -animals which received daily 0,1 ml/100g of distille...

El objetivo de este trabajo fue evaluar el efecto bioprotector Croton lechleri L. “sangre grado” frente a la toxicidad del meloxicam en Allium cepa “cebolla”. Se desarrollaron raices 2.5 cm quince bulbos, luego se expusieron durante cuatro horas tres tratamientos: T1 (100 ml agua destilada), T2 (meloxicam 1%), T3 1% mas 20 uL C. lechleri). Las tratadas con exhibieron aberraciones cromosomicas t...

The purpose of this work is to study the interaction croton fraction with amides – urea and thiourea develop technologies for obtaining accelerators vulcanization rubbers rubber industry.
