【摘 要】 目的:為研究酒制法、熟地制、黑豆制、清蒸、蔓荆子制等不同炮制工艺对广西产药食同源多花黄精成分含量的影响,优选出最佳炮制工艺。方法:采用紫外分光光度法测定广西产药食同源多花黄精不同炮制品中小分子多糖、还原糖、总皂苷、总多糖的含量,并按药典规定方法测其浸出物含量,采用归一化法计算其综合评分并比较。结果:6个指标综合评分由大到小依次为:蔓荆子制法(87.47)>清蒸(86.67)>九蒸九曝法(83.08)>酒制法(81.31)>黑豆、蜜、酒制法(77.07)>黑豆、姜、蜜制法(72.36)>熟地制法(70.55)>生品(66.16)>黑豆制法(64.35)。结论:广西产药食同源多花黄精不同炮制工艺以蔓荆子制法最优。

Abstract:Objective To study the components of Guangxi Polygonatum cyrtonemaprocessed differently, like stir-frying with wine, processing with Rehmanniae Radix Preparata, black beans or Fructus Viticis and steaming processing techniques, and select the best processing method. Methods Components of Polygonatum cyrtonema, including small molecular of polysaccharides, reducing sugar, total saponins and total polysaccharides, were determinated by UV Spectrophotometry, the extracts were determined by the way according to Chinese pharmacopoeia, and normalized method was used to calculate and compare their score. Results Comprehensive scores of the six indexes were arranged according to the order from big to small:Fructus viticis processing (87.47) > Steaming processing (86.67) >Nine steaming and nine exposure processing(83.08) > Liquor processing (81.31) > Black beans, honey, and liquor processing (77.07) > Black beans, ginger, and honey processing (72.36) > Radix Rehmanniae Preparata processing (70.55) > Unprocessed products (66.16) > Black beans processing (64.35). Conclusion Fructus viticis processing is the best method to process Guangxi edible and medicinal Polygonatum cyrtonema.

黄精为合百科植物滇黄精(Poιygonatum kingianum CoLL.et HemsL.)、黄精(Polygonatum sibiricum Red.)或多花黄精(Polygonatum cyrtonema Hua.)的干燥根茎。黄精属于药食两用中药材,其化学成分主要为低聚糖、单糖和多糖,多种氨基酸、多种甾体皂苷和人体必需微量元素、生物碱等[1]。黄精历代入药生制兼用,但传统以黄精生用“刺人咽喉”,故多炮制后入药[2]。黄精炮制渊源已久,历代以来黄精炮制方法有:九蒸九曝法、蔓荆子水蒸法、酒熬法、焙制法、黑豆煮法、酒蒸法、乳浸晒法、熟地制等[3]。目前对黄精的研究大多数为黄精及滇黄精,炮制方法为酒制法,而主产在广西的多花黄精的研究还处于空白,据笔者调查,广西民间百姓多用黑豆炮制法炮制生黄精,而黑豆制法也分为黑豆汁制、黑豆、蜜、酒制,黑豆、生姜、蜜制等。笔者主要研究广西……
