Compatibility Rules of Prescriptions of Tibetan Medicine Polygonatum cirrhifolium Based on Data Mining

[Objectives]To study the prescription compatibility rules of the Tibetan medicine Polygonatum cirrhifolium(Polygonati Rhizoma,Huangjing)based on data mining,so as to provide data support for clinical application and new drug development.[Methods]Prescriptions containing Tibetan medicine Huangjing were collected from Tibetan Medicine Prescriptions Encyclopedia and Tibetan Medicine Classic Literature Collection.The Traditional Chinese Medicine Inheritance Computing System(TCMICS 3.0)and R version 4.1.3 were used to mine and analyze the compatibility rules of prescriptions containing Tibetan medicinal material Huangjing,the rules of medication for high-frequency diseases,and the association rules of various medicinal materials.[Results]A total of 124 prescriptions were collected from the classic literature of Tibetan medicine,and the frequency statistical analysis showed that drugs compatible with Huangjing(≥15)included Tianmendong(Root of Cochinchinese Asparagus)(80),Mirabilis himalaica(Edgew.)Heimerl(Himalayan purple jasmine)(72),Jili(Tribuli Fructus)(70),Tibetan Aoruqin(Vicatia coniifolia)(58),Baidoukou(Round Cardamom Fruit)(47),Hezi(Chebulae Fructus)(45),Shouzhangshen(Rhizome of Conic Gymnadenia)(28),Yuganzi(Phyllanthi Fructus)(26),Pomegranate(25),Maohezi(Terminaliae Belliricae Fructus)(24),Zicaorong(Lacca)(23),Rougui(Cinnamomi Cortex)(15).The main diseases were yellow water disease(20),gynecological diseases(19),kidney cold disease(17),and other Tibetan medicine diseases.Association rule analysis showed that the drug combinations with the highest frequency were Huangjing—Tianmendong,Huangjing—Himalayan purple jasmine,and Huangjing—Jili.[Conclusions]The frequency of combined use of Tibetan medicine Huangjing with dry yellow water,tonifying kidney and diuresis,nourishing health,and treating gynecological diseases is relatively high.

卷叶黄精根不同极性化感物质的化感作用

With Polygonatum cirrhifolium root as the donator, the wheat, cucumber and carrot as receiver plant, the potential allelopathic effects of petroleum extracts, acetic ether extracts, n-butanol extracts and aqueous extracts from donator on the seed germination and seedling growth of three receiver plants were studied by culture plate and filter-paper. The results showed that every extracts had different allelopathic effection on different receiver plant or on different position of same receiver plant. The allelopathy intensity were related to the concentration and strengthen along with the concentration raise. The different receiver plant had distinct sensitive to the the allelopathic effect, cucumber was more sensitive than carrot and wheat. Every extracts had inhibition against seed germination and seedling growth, but inhibited root growth at high concentration and stimulated it at low concentration. In a word, every extracts had more impact on the seedling growth, however, had weak inhibition against seed germination. The average allelopathic effection of acetic ether extracts was more stronger, then n-butanol extracts, aqueous extracts and petroleum extracts. The acetic ether extracts had extremely strong inhibition on the growth of seedling and root, and n-butanol extracts on the seed germination also, which implied the Polygonatum cirrhifolium contained the allelochemicals with high polarity. In rhizosphere soil of P. cirrhifolium , the root and seedlings growth of wheat was stimulated, while cucumber and carrot was inhibited.
