From the leaves of Limonium sinuatum (L.), MILL. 6fZdvonoids were isolated. O n the basis of chemical evidence and spectroscopic data the structures of the isolated fivonoids were proved to be: apigenin, luteolin, herbacetin, gossypetin, gossypin and herbacetin-8-0glucoside. Limonium species (Plurnbaginaceae) were recorded to be rich with myricetin, quercetin, kaempferol, myricetin-3-rhamnoside and other unidentified glycosides [I]. Aurones, chalcones and anthocyanins were isolated from some Limonium flowers [2, 31. Limonium sinuatum (L.

From the leaves of Cassia siamea besides ig-sitosterol, Cassiamin A, Physcion, Chrysophanol, p-coumaric acid and apigenin-7-0-galactoside (Thalictiin), a new chromone could be isolated and its structure elucidated as 2-methyl-5-acetonyl-7-hydroxy-chromone.

S a y y a d Lantana camara L. (Vcrbenaceae) is an ornamental shrub specially grown in hedges of public and private gardens all over the U.A.R.Poisonous properties of the plant were known long ago especially to cattle and sheep.Pharmacological study of Lantana camara grown in Egypt (S h a r a f and N a g u i b 1959) showed that the alcoholic extractaf the leaves lowered the blood pressure, accelerated deep respiration, stimulated intestinal movement and inhibited uterine motility. C o l l i e r and V a n D e P i g e l (1949) observed that L. camara had antibacterial activity against Staphylococcus albus. The leaves of the plant ( W a t t , 1962) are boiled like tea and the decoction is drunk as a remedy against cough.The chemical study reported of Lantana species in general is as little as the pharmacological investigation. S c h i m m e 1 et al. (1913) isolated a volatile oil from the flowers with characteristic odour and having a low acid number (0.9).A comparison of the physical constants of the volatile oils obtained from dried flowers, fresh flowers and leaves was carried out by K a n g a (1913) who stated that all the oils were yellow and possessed a strong persistant, pleasant odour reminiscent of sage. The fresh flowers gave the highest yield 0.2%. D u t t (1960) found that the fresh leaves and tender stems of the plant collected from Allahabad and Delhi areas gave on steam distillation 0 . 2 3 4 3 2 % essential oil. He reported that the oils from the different regions are different in colours, in their constants , as well as their chemical constituents.The unique situation of Lantana camara being the highly toxic species among 40 others of the genus, its world wide distribution as a wild and cultivated plant, the variation and inadequacy of its constituents make a detailed chemical study of this plant of deemed interest in an attempt to throw some light on the potentially active constituents. The present paper deals with the study of the lipids, carbohydrates and essential oil of the plant. Experimental and Results MaterialThe material used in this investigation consisted of the separate organs (stems, leaves and fiowers) of L. camara, collected from flowering and fruiting plants, cultivated in different localities of Egypt (Assiut and Cairo).

From the herb of Calligonum comosum (Polygonaceae) the flavonoids Kaempferol, Quercetin, Quercetin-3-0-@-D-glucoside (Isoquercitrin) and Kaempferol-3-0-@-D-glucuronide, procyanidines and the carotenoids Violaxanthin and Neoxanthin have been isolated and identified mainly by chemical and spectroscopic methods.

Plants of the genus Cassia are rich in polyphenol and anthraquinone content.Cassia javanica Linn., C. didymobotrya Fres, and C. nodosa Buch-Ham. are recorded to have many medicinal uses (1).C. javanica Linn, was the subject of many studies (2-6), while C. didymobotrya and C. nodosa were studied only preliminarily (7,8). A variation in the components present in C. javanica cultivated in Egypt with those reported previously instigated this investigation. RESULTS AND DESCUSSIONThe ether fraction of the ethanol extract of C. javanica leaves was found to contain wax, a-amyrin, ß-amyrin, unknown sterol, kaempferol, kaempferol-3-methylether, kaempferol-7-methylether, traces of quercetin, emodin, and two anthraquinones. These anthraquinones were obtained in a mixture and separated by preparative silica gel chromatography. The first anthraquinone showed absorption maxima at 278, 286 (sh), 530 nm and the second at 225, 278 and 440 nm, which exhibited bath-
