An examination of the Euphorbiaceae of Hong Kong. II. The occurrence of epitaraxerol and other triterpenoids

Chemical and antioxidant evaluation of Indian gooseberry (emblica officinalis gaertn., syn. phyllanthus emblica L.) supplements

“…Indian gooseberry has been reported to contain a wide spectrum of components, including alkaloids (Khanna and Bansal, 1975), benzenoids (El-Mekkawy et al, 1995;Pozharitskaya et al, 2007), carbohydrates (Nizzamuddin et al, 1982), coumarins (Desai et al, 1977), diterpenes (Ram and Raja, 1978), flavonoids (Anila and Vijayalakshmi, 2002;Khanna et al, 1982), furanolactones (Basa and Srinivasulu, 1987), triterpenes (Desai et al, 1977;Hui and Sung, 1968) and steroids (Hui and Sung, 1968). Therefore, it should not be surprising that a wide range of health-promoting properties have been ascribed to Indian gooseberry extracts.…”

Antiproliferative Activity of the Main Constituents from Phyllanthus emblica

“…Although many studies have so far been carried out on the chemical components of P. emblica, [13][14][15][16][17][18] its detailed active principles are generally not well known. This paper deals with the inhibitory activity of 19 together with the 18 main constituents 1-18 isolated previously from P. emblica on the proliferation of B16F10 (murine melanoma), HeLa (human uterine carcinoma), and MK-1 (human gastric adenocarcinoma) cells to determine their roles in the anticancer uses of this plant.…”

“…Elaeocarpusin (10) and putranjivain A (11) were the other two main ellagitannins obtained from the fruit juice. Moreover, seven other tannins and flavonoids, geraniin (12), phyllanemblinins C and E (13 and 14), prodelphinidin B 1 (15), prodelphinidin B 2 (16) (18) were the main phenolic compounds isolated from the branches and leaves of the plant (Figs. 1, 2).…”

“…Among them, the major phenolic compounds corilagin (8) and geraniin (12) as well as hydrolysable tannin elaeocarpusin (10) and condensed tannin prodelphinidins B 1 and B 2 (15,16) showed the highest activity (GI 50 at 2 mg/ml for 12, 15, 16, and 3 mg/ml for 8, 10) against B16F10, while 15 and 16 had the highest inhibitory activity (GI 50 9 mg/ml) against HeLa, and (Ϫ)-epigallocatechin 3-O-gallate (17), known as the active constituent in green tea, showed the highest activity (4 mg/ml) against MK-1.…”

A Review of Common Medicinal Plants in Chin State, Myanmar

“…As a traditional remedy, it has been used for curing fever, smallpox, measles, intestinal and liver diseases, and as a blood purifier [140]. In the few chemical investigations performed on O. scandens the presence of a saponin, olaxoside (18), has been reported [141]. The plant has displayed acute anti-inflammatory [141] and laxative activities [141][142], acute toxicity [142], and antimicrobial [143], antioxidant [144], and antipyretic effects [145].…”
