This paper reports the quantitative analysis of glaucocalyxin A in the leaves of Plectranthus japonicus var. glaucocalyx by HPLC. The chromatographic conditions were as follows: column: Shim-pack CLC-ODS; mobile phase: methanol-water (70:30). The average content of glaucocalyxin A in the leaves is 1.30%.
AIM Abelmoschi Corolla is a well-known herbal medicine used for the treatment of chronic renal disease. Flavonoids are the major bioactive ingredients of Abelmoschi Corolla, but some non-flavonoid components also exist in this herb. In order to clarify the influences of non-flavonoid components on the pharmacokinetics profile of the flavonoid fraction from… (More)
An HPLC method for the determination of hyperin in Sanguisorba officinalis L. was investigated. 0.5 g of dried powdered crude drug was weighed accurately in a 50 mL volumetric flask added with 40 mL methanol, supersonicated for 30 min and then made up to volume with methanol. The sample solution was separated on a Shim-pack ODS column(6.0 mm i.d. x 150 mm,… (More)

A HPLC method for the determination of chrysophanol in Semen Cassiae was investigated. The result showed that this method was simple, specific and accurate. The recovery was 99.0% and relative standard deviation was 1.8%. The method is useful for the quality control of this medicinal meaterial.
The quantitative changes of flavonoids in Epimedium koreanum in different collecting periods were determined by HPLC and UV spectrophotometry. The result shows that the highest content of flavonoids is found in the flowering period (May).
The contents of myristicin and safrol in the volatile oil of nutmeg and its processed products were determined by HPLC. This method is fast, accurate and gives good resolution. It has also been confirmed that myristicin tends to decrease in varying degrees after the nutmeg has been processed.
A HPLC method for the determination of hyperin in Epimedium koreanum was investigated. The result shows that this method is simple, specific and accurate. The recovery was 97.4% and relative standard deviation was 1.2%. With good reproducibility and wide response linearity, the method can be used for the quality control of this herbal medicine.
