摘要： A single rapid procedure for the quantitative and qualitative analysis of flavonoid glycosides and steroidal glycosides, in natural products, has been developed. The material is extracted with aqueous solutions of polar organic solvents in an ultrasonic bath. Interfering compounds are removed by pre-purification procedures prior to instrumental analysis by High Pressure Liquid Chromatography with Negative Ion Electrospray Mass Spectrometric Detection and on-line Diode Array Ultraviolet-Visible Spectroscopy. The analysis of flavonoid and steroidal glycosidic compounds in HOSTA leaves served as a model system.

摘要： A method of growing diamond crystals in excess of 10 .mu.m in diameter from industrial diamond "seeds" having mean diameters of approximately 1.5 .mu.m is disclosed. The diamonds are grown by exposing the seed diamonds to C.sub.70 in the presence of reducing agents such as phosphorus or selenium in evacuated cells at moderate temperatures and pressures.

摘要： A method of growing single crystal diamonds in excess of 10 .mu.m in diameter from industrial diamond "seeds" having mean diameters of approximately 1.5 .mu.m is disclosed. The diamonds are grown by exposing the seed diamonds to C.sub.70 in the presence of elemental reducing agents such as phosphorus or selenium in evacuated cells at moderate temperatures and pressures. In another aspect the invention diamonds are grown by exposing diamond seed particles to vapour phase C.sub.70 in the presence of a gas phase metal carbonyl, such as F.sub.5 e(CO) in a temperature range of 400.degree. C. to 700.degree. C. to cause at least some of the diamond seed particles to grow.
