BACKGROUND
Rhizomes of Alpinia calcarata Roscoe (Family: Zingiberaceae) possess several bioactivities and are used in the traditional medicinal systems of Sri Lanka.
METHODS
The present investigation was carried out to standardize the rhizomes of A. calcarata by (a) screening for phytochemicals (b) determination of physico-chemical parameters and (c) development of a Densitogram.
RESULTS
Phytochemical screening revealed the presence of polyphenols, tannins, flavonoids, steroid glycosides and alkaloids in A. calcarata rhizomes. The percentages of moisture, total ash, acid insoluble ash, water soluble ash, ethanol extractable matter and water extractable matter were of 5.5 - 6.8, 8.3 - 8.8, 0.036 - 0.040, 7.2 - 7.8, 22.6 - 24.8 and 18.6 - 20.5 respectively.
CONCLUSION
The results obtained from this study can be used to standardize rhizomes of A. calcarata grown in Sri Lanka.
背景
距瓣姜（姜科）的根茎具有多种生物活性，在斯里兰卡的传统医学体系中有所应用。
方法
本研究通过（a）植物化学物质筛选、（b）理化参数测定以及（c）光密度图的绘制来对距瓣姜的根茎进行标准化。
结果
植物化学筛选显示距瓣姜根茎中存在多酚、单宁、黄酮类化合物、甾体糖苷和生物碱。水分、总灰分、酸不溶性灰分、水溶性灰分、乙醇可提取物和水可提取物的百分比分别为5.5 - 6.8、8.3 - 8.8、0.036 - 0.040、7.2 - 7.8、22.6 - 24.8和18.6 - 20.5。
结论
本研究所得结果可用于对斯里兰卡种植的距瓣姜根茎进行标准化。
