“…The Et 2 O layer was partitioned between hexane and MeOH, and the MeOH layer was further chromatographed successively over Sephadex LH-20, silica gel, MCI-gel CHP 20P and Chromatorex ODS to afford 1 and 2, as well as 17 known compounds. The known ones were identified as naringenin, 6) eriodictyol, 6) kaempferol, 7) dihydrokaempferol, 8,9) quercetin, 7) naringenin 7-O-glucoside (prunin), 10) naringenin 7-O-(6Љ-O-galloyl)-glucoside, 10) naringenin 7-O-(6Љ-O-trans-p-coumaroyl)-glucoside, 11) kaempferol 3-O-rhamnoside, 7) quercetin 3-O-rhamnoside, 7) myricetin 3-O-rhamnoside, 7) 2-(2-methylbutyryl)-phloroglucinol 1-O-b-D-glucopyranoside (multifidol glucoside) (5), 12) (Ϫ)-epigallocatechin 3-O-gallate, 13) 1,2,3,6-tetra-O-, 14) 1,2,4,6-tetra-O-, 15) and 1,2,3,4,5-penta-O-galloyl-b-Dglucose, 16) and decarboxyellagic acid 17) by comparison of the physical and spectral data with literature values.…”

Phyllanthus emblica L. (Euphorbiaceae) is a shrub or tree native to subtropical and tropical areas of China, India, Indonesia and the Malay Peninsula. The fruit has been widely used for antiinflammatory and antipyretic treatment. The root, leaves and bark are also used for the treatment of indigestion, diarrhea or dysentery, eczema and wart. As a continuation of investigation on the constituents of this plant,

“…Ion at m/z 433 and 447 fragmented in MS/MS to produce ion that corresponded to standard quercetin, neural loss of 132 and 146 from each ion, respectively demonstrating presence of pentoside and deoyhexoside. [49] Thus, peaks 3 and 4 were tentatively identified as quercetin-pentoside and quercetin-deoxyhexoside. Peak 5 was tentatively identified as diosmetin-diglycoside based on the deprotonated ion [M-H]at m/z 607.…”

Solvents and extraction procedures, [4] together with different methods available to evaluate antioxidant [5] and antibacterial activity [6] have been contributed to the variation of observed plant extract effects. In frequently reported studies, polyphenols have been suggested as responsible for the potent biological activities of extracts prepared using methanol and ethanol. [7] Acacia farnesiana is a plant from the subfamily Mimosoideae of Leguminosae (Fabacea). It is well known cultivated for its flower to be utilized in the production of cassie perfume. [8] The plant is also known for its ethnopharmacological properties and a number of scientific studies have been carried out previously. For instance, the bronchodilator and anti-inflammatory effect of glycosidal fraction of A. farnesiana was reported. [9] The root is reputed active against snake bite venom [10] and compounds of diterpenes and flavonoids were previously isolated from the root extract. [11] The methanolic extract of Acacia farnesiana bark exhibited antidiarrhoeal activity against castor oil and magnesium sulphate induced diarrhea along with antimicrobial activity against common pathogens responsible for diarrhoea in vitro. [12] Previously, the anti-inflammatory property of the

“…Different parts of the plant have been used for the treatment of various ailments (Sahu et al, 1998). Previous chemical investigation on the flowers and pods of the plant have revealed the presence of four homoterpene lactones, flavone glycosides and several polyphenolic compounds (El Sissi et al, 1974). Its leaves are also consumed by livestock and white-tailed deer (Ramirez et al, 1995).…”

Acacia farnesiana (L.) Willd. is a very important multipurpose species in Egypt and many other countries. It is valued as forestry and as an ornamental tree. Its flowers produce a perfume called " cassie " extensively used in European perfumery. The present study aims to the determination of the effect of helium-Neon (He-Ne) light irradiation on accelerating the germination of A. farnesiana seeds, which have dormancy due to impermeability of seed coat of water. The seeds were exposed to He-Ne laser light for 1, 3, 5, 7, and 9 minutes with different irradiance 0.03, 0.20, 0.61, 1.14, and 1.70 W/cm 2. Gibberellic acid (GA), indole-acetic acid (IAA), abscisic acid (ABA) as well as phenols were determined after 48h in treated and untreated seeds. Thin sections in the testa were also made. Germination indices: the time to germinate, germination period, germination percentage and germination speed were determined. The results showed that irradiation by the laser beam of the seed coat, (testa or pericarp, the envelope enclosing the seed embryo), succeeded in perforating the seed coat at one or more positions. Generally, an increase in irradiance and exposure time of He-Ne laser light irradiation increased levels of endogenous promoting substances (GA and IAA), and decreased levels of endogenous inhibiting substances (ABA and phenol) in seed coats. We conclude that irradiance of seeds with He-Ne laser light at 1.70 W/cm 2 for 9 min. significantly affected germination indices when compared with control seeds.
