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...

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...

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.

Background Essential oils are complex systems which consist mainly of volatile compounds of lipophilic source, as terpenes, sesquiterpenes and some non-terpenes [1]. Resulting from secondary metabolism, essential oil from Croton argyrophyllus (EOCA) is commonly extracted from its leaves. It is known that the essential oils from Croton species exhibit good antioxidant activity against DPPH free ...

The Greek colonial foundations along the Ionian Sea coast of southern Italy may generally be divided into Achaian and non-Achaian cities (fig. 1). Of the Achaian cities, Sybaris and Croton were founded first, towards the end of the 8 century BC, followed by Caulonia to the south and Metapontum to the north. These latter cities were settled by Croton and Sybaris in order to create a buffer with ...
