ABSTRACT
This study was aimed to investigate the comprehensive ecological factors of Hippophae rhamnoides L. and their regional suitability in China. Based on field survey, specimen examination and literature investigation, ecologi-cal factors and appropriate production areas were analyzed by Traditional Chinese Medicine Geographic Information System (TCMGIS-II). The results showed that the proper region (with similarity of 95%~100%) of H. rhamnoides L. accounts for 737 994.71 km2, including 15 provinces/municipalities and 387 counties/cities. The largest area among them is Tibet autonomous region with area of 313 857.73 km2 (42.53%), followed by Sichuan province (223 987.02 km2, 30.35%), Gansu province (66 314.43 km2, 8.99%) and Shanxi province (4 237.79 km2, 0.57%). There are also certain appropriate production areas distributed in Liaoning province, Beijing, Chongqing and Hubei province. It was concluded that this system is much valuable to the recognition of the formation of the producing area, the division of adaptive area, introduction and acclimatization of medicinal materials. It also provided a scientific reference for the introduction and cultivation of H. rhamnoides L. Through further field study and experiments, these new areas have the potential to be developed into suitable production region of H. rhamnoides L. in the future.
ABSTRACT
This study was aimed to establish quality standards of fruit of Hippophae tibetana Schlechtend.. The medical material was identified by microscopy and thin layer chromatography (TLC). According to methods recorded in the Chinese Pharmacopoeia (2010 edition), the contents of moisture, total ash, acid-insoluble ash and alcohol-sol-uble extract were determined. The HPLC method was applied in the determination of quercetin, kaempferol and isorhamnetin content. The results showed that the microscopic characteristics of Tibetan medicine H. tibetana were identified. The TLC and content determination methods of quercetin, kaempferol and isorhamnetin were estab-lished. It was concluded that the established qualitative and quantitative methods can be used for quality control of the fruit of H . tib e tana.
ABSTRACT
<p><b>OBJECTIVE</b>To explore material basis of the pharmacological differences between the roasting and pro-roasting Raphani Semen.</p><p><b>METHOD</b>The two new sulfur-containing compounds (A209 and B221) were found changed after processing in the water decoction. The common precursor-C3 of A209 and B211 and the precursor of C3 were seperated and purified. Their transforming relationship was proved.</p><p><b>RESULT</b>The result showed that glucosinolates could decompose into sulforaphane and transform into A209 and B221 further in the boiling process.</p><p><b>CONCLUSION</b>This study provides some experimental evidences for revealing the mechanism of Raphani Semen processing.</p>
