| 摘要: |
| 三七是中国云南省的“第一药材”,云南文山三七是三七的道地药材。三七块根的横截面为黄白色至紫色。紫色块根约占研究块根总数的28.21%,其中柱鞘、内皮层、皮层或表皮为紫色。特征颜色反应和紫外——可见光谱表明:三七块根紫色素属于黄酮类化合物,可能含有酚性邻位二羟基,不含类胡萝卜素、查耳酮、噢哢、异黄酮、儿茶素。花色苷和/或其苷元花色素奠定了紫色块根着色的基础,其他的非红色的黄酮类化合物起共色素的作用。块根的平均花色苷含量和平均总皂苷含量均以纯紫色块根的为最高,其次是黄紫混合色块根的,纯黄色的最低。块根的花色苷含量差异达到极显著水平,但总皂苷含量差异却没有达到显著水平。每个块根都含有不同量的花色苷,随花色苷量的增加,块根的紫色一般逐渐明显。块根的花色苷含量与其总皂苷含量之间呈显著正相关,相关系数r=0.355。本文可为三七块根颜色呈现的机理探索及其色素的分子结构鉴定提供参考。 |

| Abstract: |
| Panax notoginseng is“the first medicinal material”in Yunnan of China and P.notoginseng produced in the Wenshan eparchy of Yunnan is the Genuine Medicinal Material of P.notoginseng. The transverse sections of the root tubers of P.notoginseng range from yellowish white to purple. The root tubers with pure purple occupy about 28.21% of the root tubers researched,and their pericycles,endodermises,cortexes or epidermises are purple. Specific color reactions and UV-vis spectra indicated that the purple pigment of the root tuber of P.notoginseng belongs to flavonoids,probably holding phenolic o-dihydroxyls,excluding carotenoids,chalcones,aurones,isoflavones and catechins. Anthocyanins and/or their aglycones,namely anthocyanidins,underlay the pigmentation of the purple root tuber and other non-red flavonoids function as co-pigments. The average anthocyanin content and the average total ginsenoside content of the root tubers with pure purple are all the highest,next are those of the root tubers with farraginous color of yellow and purple,and the lowest are those of the root tubers with pure yellow,which is consistent with the changing trend of the color hues of the different root tubers. The difference of anthocyanin contents of the root tubers with different colors reaches the most significant level,but the difference of anthocyanin contents does not reach the significant level. Every root tuber contains anthocyanins of different quantity,and along with increase of the anthocyanin content,the purple of the root color basically becomes more and more obvious gradually. The anthocyanin content of the root tuber is positively related with the total ginsenoside content at the significant level and the correlation coefficient(r)is 0.355. This paper can provide a reference for the exploration on the mechanism of the tuber coloration and the identification of the molecular structures of the tuber pigments of P.notoginseng. |
