  - naphthalene acetic acid
Opposite effects of synthetic auxins, 2,4-dichlorophenoxyacetic acid and 1-naphthalene acetic acid on growth of true ginseng cel
      
The highest frequency of callus induction obtained from leaflet explants was on Murashige and Skoog (MS) medium containing 2.0 mg/L of α-naphthalene acetic acid (NAA) and 0.5 mg/L of kinetin combination.
      
brachyandrum indole butyric acid and α-naphthalene acetic acid (1 μM) were almost equally effective.
      
Continous propagation of the bulblet cultures was achieved on a modified Murashige and Skoog agar medium containing 1-naphthalene acetic acid (0.1 mg/l) and kinetin (0.1 mg/l) as phytohormones.
      
Higher 1-naphthalene acetic acid concentrations (1 mg/l) resulted in increased callus formation.

Seventeen 1, 1-diphenyl-2-naphthylethylenes were synthesized through Grignard reaction followed by acid catalyzed water elimination and tested for their antifertility effects in rats or rabbits. Three of them, compounds 6931, 70082, 70083, completely prevented fertility in female rats at a dose of 10 mg/kg/day by oral adiministration for six days. Compound 6931 was shown to be the most effective which caused complete inhibition of pregnancy in female rabbits at an oral dose of 5 mg/kg/day for three days. Further...

Seventeen 1, 1-diphenyl-2-naphthylethylenes were synthesized through Grignard reaction followed by acid catalyzed water elimination and tested for their antifertility effects in rats or rabbits. Three of them, compounds 6931, 70082, 70083, completely prevented fertility in female rats at a dose of 10 mg/kg/day by oral adiministration for six days. Compound 6931 was shown to be the most effective which caused complete inhibition of pregnancy in female rabbits at an oral dose of 5 mg/kg/day for three days. Further pharmacological studies revealed that this compound was also highly effective against implantation in female dogs and monkeys and no undesirable side effects has been found at different dosage levels. It was then subjected to clinical trials but the results were not very encouraging.It is interesting to note that the antifertility effects markedly decreased when the olefinic hydrogen in the molecule was replaced by bromine, chlorine or nitro group.

本文介绍用α-萘乙酸乙酯与相应的格氏试剂反应,继以酸催化脱水,得三芳基取代乙烯,然后用卤素、硝酸等处理,合成了十七个1,1-二苯基萘乙烯类化合物。所有化合物对大白鼠或家兔进行抗生育试验,发现化合物6931,70082,70083,在10mg/kg/天剂量下,口服六天,对大白鼠有100%的抗生育效果。其中化合物6931在5mg/kg/天剂量下,口服三天能完全抑制家兔生育。当分子中乙烯氢原子被卤素及硝基取代后,抗生育效果显著下降。

Callus tissue of Salvia miltiorrhiza Bge.can be used to biosynthesize diterpinequinones such as Tanshinone.The Callus tissue was grown on Murashige-Skoog(MS)medium containing 2,4-Dichlorophenoxyacetic acid(2,4-D)lmg/l or Indole aceticacid(IAA)lmg/l or Naphthyl acetic acid(NAA)ling/l in the dark.It was found,after three weeks,that callus tissue growing on medium with IAA or NAA turned red.An orange-red crystalline substance was isolated from the chloroform extract of red callusdry powder by silica column chromatography.It...

Callus tissue of Salvia miltiorrhiza Bge.can be used to biosynthesize diterpinequinones such as Tanshinone.The Callus tissue was grown on Murashige-Skoog(MS)medium containing 2,4-Dichlorophenoxyacetic acid(2,4-D)lmg/l or Indole aceticacid(IAA)lmg/l or Naphthyl acetic acid(NAA)ling/l in the dark.It was found,after three weeks,that callus tissue growing on medium with IAA or NAA turned red.An orange-red crystalline substance was isolated from the chloroform extract of red callusdry powder by silica column chromatography.It was found to be identical with cryp-totanshinone by comparison with their mp,HPLC,UV and MS data.

本文报道了丹参愈伤组织的诱导及其化学成分的初步研究。试验采用Murashige-Skoog(MS)培养基,分别加入2,4—二氯苯氧乙酸(2,4-D)1mg/l、β-吲哚乙酸(IAA)1mg/l、α--萘乙酸(NAA)1mg/l,在黑暗条件下培养三周后发现附加有 IAA 或 NAA 的培养基中愈伤组织变为红色。从干燥的红色愈伤组织中,用氯仿提取、硅胶柱层分离到一种橙红色结晶,经鉴定为隐丹酮。

The calluses and adventitious buds can be induced from the leaf explant of Dendranthema morifolium (Ramat.)Tzvel. by adding 0.05-0.3 mg/1 β-ec-dysone together with 0.5-3.0 mg/1 BA(1 : 10) to the medium, but roots can not be induced.The formation of roots can be gained by putting β-ecdysone plus NAA in the medium, but buds can not be achieved. The growth of dormant axillary buds can be promoted with 0.5-4.0 mg/1 β-ecdysone plus BA or NAA and the roots can be induced from the basal portions of the buds (or shoot)...

The calluses and adventitious buds can be induced from the leaf explant of Dendranthema morifolium (Ramat.)Tzvel. by adding 0.05-0.3 mg/1 β-ec-dysone together with 0.5-3.0 mg/1 BA(1 : 10) to the medium, but roots can not be induced.The formation of roots can be gained by putting β-ecdysone plus NAA in the medium, but buds can not be achieved. The growth of dormant axillary buds can be promoted with 0.5-4.0 mg/1 β-ecdysone plus BA or NAA and the roots can be induced from the basal portions of the buds (or shoot) with 0.25-4.0 mg/1 β-ecdysone in the medium. So, the effect of β-ecdysone is mainly similar to that of auxins.

把β-蜕应激素〔1〕加入基本培养基中,观察对菊花叶外植体分化芽和潜伏腋芽生长的影响,发现0.05—0.3毫克/升的β-蜕皮激素以1:10的比例分别与0.5—3.0毫克/升的6-(艹卡)基瞟呤(6-BA)配合,使能叶块组织成愈伤组织并分化出不定芽,但不分化形成根;与α-萘乙酸(NAA0)配合则易形成根而不分化芽:0.5—4.0毫克/升的β-蜕皮激素与6-BA或NAA配合能促进潜伏腋芽萌发;0.25—4.0毫克/升的β-蜕皮激素能使“无根苗”生根形成完整植株。由上可见,β-昆虫蜕皮激素的作用主要和生长素类似。
