Sensory Characteristics and Antioxidant Activity of Zanthoxylum bungeanum Maxim. Pericarps

Zanthoxylum bungeanum extracts were prepared using seven solvents: water, methanol, ethanol, acetic acid, ethyl acetate, chloroform, and benzene. The volatile composition in the extracts was qualitatively analyzed using headspace solid‐phase microextraction coupled with gas chromatography mass spectrometry detection, and the alkylamide composition was determined using high‐performance liquid chromatography. The extract compositions differed with respect to the solvents. A total of 49 volatile components belonging to four groups, terpenoids, alcohols, esters, and ketones, were identified in the extracts. The Z. bungeanum extracts were either ester or terpenoid type, dominated by linalyl acetate. The extracts were divided into three distinct groups based on principal component analysis and hierarchical clustering analysis. Water, methanol, and ethanol extracts could be applied in the food and pharmaceutical industries.     

Aliphatic acid amides of the fruits of Zanthoxylum piperitum

Six aliphatic acid amides (1-6) were isolated from the pericarp of Zanthoxylum piperitum fruits. MS and NMR spectroscopic investigation revealed that these compounds have a ketone and/or hydroxyl group(s) in the unsaturated aliphatic acid moiety of the structure of the amides. Combinations 3-4 and 5-6 are stereoisomers in terms of the relative configurations of their two asymmetric carbons.     

花椒果实分泌囊发育过程的超微结构研究

电镜观察结果表明,花椒(Zanthoxylum bungeanum Maxim.)果实分泌囊是由裂生方式形成,由鞘细胞、上皮细胞和油腔构成。对分泌囊的原始细胞、油腔发生和扩大以及发育成熟3个时期的超微结构研究表明,其精油是在分泌囊油腔发生时开始积累,以油滴形态存在于上皮细胞的质体内及其周围的细胞质中。根据各细胞器的变化规律分析,质体是精油合成的主要场所,内质网参与精油的合成和转运,线粒体为上述活动提供能量。上皮细胞内积累的精油可能通过两种途径排出细胞,分泌至油腔内贮存。鞘细胞内也积累精油,其主要合成场所也与质体有关,以后转运至上皮细胞内。成熟分泌囊的质体由于功能改变,其内出现蛋白质结晶和淀粉粒。     

花椒果实分泌囊超微结构的研究

利用电子显微镜对花椒果实分泌囊的超微结构进行研究,表明分泌囊上皮细胞和鞘细胞的最显著特征是具许多含嗜锇物质的质体。这些质体内膜结构不发达,周围分布大量内质网槽库、含油滴的液泡和环状油滴。在此基础上,对质体的功能以及精油合成、贮存和转运的可能场所和途径进行了讨论。     

狭叶花椒化学成分研究——Ⅰ.Yangambin的分离鉴定

从芸香科(Rutaceae)花椒属植物抉叶花椒(Zanthoxylum stenophyllum Hemsl.)根皮中分到一种木脂体,通过MS、IR、UV、NMR、DEPT和双共振技术,确定其结构为(IR,2S,5R,6S)-2,6-Bis(3,4,5-trime-thoxyphenyl)-3,7-dioxan-bicyclo[3,3,0]Octane.即Yangambin。     

刺壳椒化学成分研究

刺壳椒又名三百棒 ,系芸香科花椒属植物。其根、茎、果实均可供药用〔1,2〕。刺壳椒化学成分的研究尚未见报道。我们曾对数种原产于中国的花椒属植物进行过化学成分的研究 〔3～ 12〕,并讨论了花椒属中Zanthoxylum和 Fagara2个亚属合并为广义的 Zanthoxylum的合理性〔13〕。为了寻找新的生物活性成分 ,并给花椒属的化学系统学提供一定依据 ,我们初步研究了刺壳椒的化学成分 ,从其茎的乙醇提取物中分得 9个化合物 ,其中 6个分别鉴定为白藓碱 ( ) ,γ-花椒碱 ( ) ,6,7,8-三甲氧基香豆素 ( ) ,β-谷甾醇 ( ) ,胡箩卜甙 ( )和一长链混合脂肪酸…     

Characterization and biological evaluation of six new dimeric lignans with an unusual α,β-unsaturated ketone motif from Zanthoxylum simulans

Investigation of the bark of Zanthoxylum simulans afforded six new dimeric lignans zanthpodocarpins C–H (1–6) bearing an unusual α,β-unsaturated ketone group. The new structures of 1–6 were determined by using detailed spectroscopic analysis. All of the isolated compounds were examined for their inhibitory effects against rat joint synovial cell and splenocyte proliferation. Compounds 1–6 showed potent anti-inflammatory activities with IC₅₀ values ranging from 18.6 to 36.1 μM, and 13.8 to 74.3 μM.     

Sichuan Peppers and the Etymology of <Emphasis Type="Italic">Fagara</Emphasis> (Rutaceae)

Sichuan Peppers and the Etymology of Fagara (Rutaceae). We present a synopsis of the history and derivation of faraga from its Arabic origin through confusion with the Chinese fajiu. Fagara, or Zanthoxylum, a medicinal spice, has a venerable history of human uses beginning in China, spreading through West Asia to Europe, and finally reaching the New World.

Los Pimientos de Sichuan y la Etimología de Fagara (Rutaceas). Nosotros presentamos un resumen de la historia y derivación de fagara a partir de su origen Arabe pasando por su confusión con el nombre Chino, fajiu. Fagara, o Zanthoxylum, una especia medicinal que tiene una venerable historia de usos humanos que comienzan en China, se propagan a travez del Asia Occidente hacia Europa llegando finalmente al Nuevo Mundo.

     

Folin-Ciocalteu比色法测定花椒中多酚含量的研究

研究了以没食子酸为标准品,采用Folin-Ciocalteu比色法,测定花椒多酚含量的适宜条件。结果表明:当Folin-Ciocalteu试剂与10%Na2CO3溶液之比为1∶2(V∶V),Folin-Ciocalteu试剂体积为4 mL,反应温度为25℃,反应时间为120 min时,多酚含量在1~6μg/mL范围内与吸光值呈良好的线性关系。测定了4种花椒中的多酚含量,四川青花椒多酚含量最高。
