PHYTOCHEMICAL STUDY OF THE LEAVES OF ZIZIPHUS SPINA-CHRISTI L. WILLD
Investigation of the leaves of Z. spina-christi L. Willd resulted in the isolation and identification of ceryl alcohol, b-sitosterol, ursolic acid, betulinic acid, fatty acids (myristic, stearic, oleic, linoleic, linoleic and arachidic acids), flavonoidal compounds (taxifolin, dihydrokaempferol, taxifolin-3-O-glvcoside and apigenin-7-O-glucoside). In addition, a chromatospectrophotometric method was adopted for quantitative estimation of the flavonoidal content.

A PHYTOCHEMICAL STUDY OF THE FRUITS OF CERTAIN CASSIA SPECIES CULTIVATED IN EGYPT
The fruits of Cassia javanica Linn., C. siamea Lam., C. fistula L. and C. didymobotrya Fres. are subjected to a phytochemical screening followed by isolation and identification of their constituents. The study revealed the presence of flavonoids, anthraquinones, chromones, alkaloids, sterols and/or triterpenes together with hydrocarbons and alcohols in the different fruit pericarps.
The physical as well as chemical characteristics of the fixed oil of the seeds are determined. In addition the fatty acids of each individual seed oil are identified by gas-liquid chromatography.

NEOLIGNANS AND ALKALOIDS FROM LICARIA ARMINIACA (NEES) KOSTERM. PART: 1
Two neolignans 3a-allyl-5-methoxy and dimethoxy-2-(3,4`-methylenedioxy phenyl)-3-methyl-2,3,3a,4,5,6-hexahydro-6-oxobenzofurans and four minor alkaloids (bracteoline, o-methyl bracteoline, a-dehydroreticuline and unknown alkaloid) have been isolated from the wood stem and stem bark of Licaria arminiaca F. Lauraceae. These alkaloids although known were isolated for the first time from the genus Licaria. The structures of three of them were deduced from spectral and chemical evidence.

FACTORS CONTROLLING MEASUREMENT OF THE CRUSHING STRENGTH OF CALCIUM SULFATE GRANULES EVALUATED BY BALL MILL
Calcium sulfate dihydrate granules were prepared using (10%) aqueous PVP solution. The crushing strength of the prepared granules was evaluated according to the method adopted by Mehta et. al. using a ball mill. Many controlling factors such as the proportion of the feed, granule size (1875, 1025, 558 m), speed of rotation (low; I, moderate; II and high; III), type of balls (small porcelain, mixed porcelain and glass balls) and number of balls on the linearity of the equation were studied. The results obtained revealed that, the linearity of the equation was obvious as the proportion of the granules was increased. Granules of small size (1025 and 558 m ) gave under-estimation results. Upon increasing the time of milling, the linearity of the equation was obeyed. This finding was also achieved at law speed and on decreasing the number of balls. On the other hand, the linearity was obtained on decreasing the time of milling using glass and mixed balls as grinding media. In addition the time of milling was decreased at high speed.

NEW REAGENTS FOR DETECTION OF PHENOTHIAZINE DRUGS ON THIN LAYER PLATES
About 50 new reagents have been developed for the detection of phenothiazine drugs on TLC plates by giving different colours. Each reagent consists of an amine and an oxidant. Most of the developed reagents are very sensitive for detection of even l mg phenothiazine drug.

SPECTROPHOTOMETRIC DETERMINATION OF CERTAIN BENZODIAZEPINE DRUGS
A rapid adequate spectrophotometric method was developed for the quantitative determination of diazepam, nordiazepam, oxazepam and chlordiazepoxide in pure form and in pharmaceutical preparations. The method is based on the hydrolysis of the above mentioned drugs in acid medium for 20 minutes in a boiling water bath. The formed amines were condensed with p-dimethylaminocinnamaldehyde in acidic methanol to form pink coloured product with absorption maxima at 500 and 530 nm for diazepam and the other drugs respectively. Beer's law was obeyed over the range of 0.5-10 mg ml-1 for all studied drugs. The produced colour is stable for 2 hours for diazepam and at least for 24 hours for the other studied drugs. The method is simple, sensitive and particularly suited for routine analysis of these drugs.
