RESUMO

As revealed by the investigation on the name change, biological characteristics, artificial cultivation, and edible history of Polygonatum kingianum var. grandifolium, it was described as a variation pattern of P. kingianum in the Chinese version of Flora of China(1978) and as a variant of P. kingianum in the revised English version of the Flora of China(2000). P. kingianum var. grandifolium, long been consumed as food by local folks, has been widely cultivated in its natural distribution area and circulated as Polygonati Rhizoma in the market. The important biological properties of P. kingianum var. grandifolium make it possess a great potential of being consumed as both medicine and food. The shoots of P. kingianum var. grandifolium sprout immediately out of the ground after seed germination and a new seedling will be formed at the same year, implying that its seedling cultivation period is at least two years shorter than that of P. cyrtonema. It can sprout more than twice a year, and the adult plants always remain evergreen, thereby obtaining higher biomass. Its rhizome biomass can be more than one time higher than that of P. cyrtonema. With reference to the diploid P. cyrtonema, flow cytometry revealed the polyploid and aneuploid forms in natural populations, which were tall and light-adapted with large underground rhizome. It can grow normally under the forest canopy and in the open field. Furthermore, P. kingianum var. grandifolium has important theoretical values for the study of ploidy variation, bud dormancy mechanism, etc.

RESUMO

The flower of Polygonatum cyrtonema has good edible and medicinal values. In this study, four samples of P. cyrtonema flowers from different regions were selected as test materials. The contents, composition and antioxidant activities of lipid-soluble pigments and alcohol-soluble components were determined under different light and temperature conditions, which help to reveal the discoloration reason and the composition variation patterns during storage. The results showed that light and temperature had different effects on the lipid-soluble pigments and alcohol-soluble components in the dried flowers during storage. After storage for 4 weeks, the contents of total chlorophyll, carotenoids, phenols and saponins in the samples exposed to light respectively decreased by 62.62%, 66.4%, 68.7% and 43.4% compared with those in the dark. The decreases in the contents of chlorophyll a, chlorophyll b, lutein, β-carotene and zeaxanthin were 64.64%, 56.74%, 59.2%, 77.7% and 45.4%, respectively. The contents of pigments and components in the samples stored at-20 ℃ were significantly higher than those at room temperature and 4 ℃, indicating that low temperature was conductive to the stability of lipid-soluble pigments and alcohol-soluble components. The samples stored at low temperature and in the dark had the strongest free radical scavenging activity. The results suggest that P. cyrtonema dried flowers should be stored in low temperature environment without light, which can slow down the degradation of internal components. The study provides a theoretical basis for the production, processing and storage of P. cyrtonema flowers.

RESUMO

The medicinal and edible Polygonatum cyrtonema is one of the original species of Polygonati Rhizoma. In this study,HPLC fingerprints for 25 batches of P. cyrtonema from 6 provinces were established. A total of 14 common peaks were identified and the similarities of the fingerprints were in the range of 0. 939-0. 999. In additon, the partial least squares-discriminant analysis(PLSDA) demonstrated that the samples had low discriminability except for JX-1 and most components of them had no significant correlation with environmental factors such as longitude, latitude, and altitude. Thus, chemical composition specificity of P. cyrtonema in natural distribution areas had no obvious regularity and their variation might be induced by the local environment. This conclusion explained the lack of records about Dao-di area of Polygonati Rhizoma. However, JX-1 boasted significantly higher content of 5-hydroxymethylfurfural(HMF) and 4',5,7-trihydroxy-6,8-dimethylhomoisoflavone( HIF), thick and long inflorescence and rhizome, and extremely high yield. Therefore, excellent variety of P. cyrtonema might have great potential to improve the quality and yield of Polygonati Rhizoma. Moreover, three components of HMF, polygonalline A(PA), and HIF were identified in the fingerprint. Among them, HMF has the activities of blood rheology improvement, antioxidation, and anti-myocardial ischemia and PA is an indolizine alkaloid with potential anti-inflammatory activity. HIF, the characteristic homoisoflavone in Polygonatum, has the pharmacological activities of regulating blood glucose and anti-tumor. A quantitative analysis method can provide a theoretical basis for the improvement of the quality evaluation of Polygonati Rhizoma.

RESUMO

In order to reveal the main nutrients and functional ingredients in the shoots of Polygonatum cyrtonema, the polysaccharides, proteins, amino acids, and total phenols were determined. The tested samples cultured in Ma'nijiaonong, Hengtang village, Tianmushan town, Lin'an, Zhejiang, which were collected from three provenances(Pan'an and Longquan in Zhejiang and Qingyang in Anhui). The results showed that the polysaccharide content of the shoots varied from 2.34% to 12.73%, roughly one-third of rhizomes. The protein content varied from 107.75 to 192.49 mg·g~(-1), nearly 5.50 times more than rhizomes. Moreover, the average of total amino acid content was 193.13-248.74 mg·g~(-1), approximately 4.16 times of rhizomes. And the essential amino acids account for 35.57%-39.44% of the total amino acids content, which was close to the standard of the ideal protein proposed by FAO/WHO(the essential amino acid/total amino acid is about 40%). In addition, the taste amino acids(TaAA) changed from 160.12 to 208.29 mg·g~(-1), revealing the material basis of "shoots were extremely delicious" in Chinese ancient herbal medicine. Additionally, the total phenols varied from 51.21-58.76 mg·g~(-1), about 2.96 times of rhizomes. The DPPH free radical scavenging rate of tested shoots was over 95%, which obviously superior to rhizomes. Therefore, the shoots of P. cyrtonema is a very high-quality vegetable and functional food with good development potential. Furthermore, the main nutrients and functional substances in P. cyrtonema shoots are closely related to the provenances and harvesting seasons. It is important to improve the quality and yield of the shoots by strengthening the variety of breeding and cultivation techniques.

RESUMO

The flower color of Dendrobium catenatum(D. officinale) tends to fade during storage. In order to clarify the influence of storage conditions on the pigment components in flowers, two conditions were applied:temperature and illumination. The contents of pigments in the D. catenatum flower were determined by UV-Vis spectrophotometry and HPLC, and the changes of them during storage were analyzed. The results showed that illumination and temperature had an effect on the pigments of D. catenatum flower during sto-rage. Illumination significantly promoted the degradation of pigments. The contents of total chlorophyll, carotenoids and anthocyanins in the light samples were significantly lower than those in the dark. The total chlorophyll, carotenoids and anthocyanins in the light samples were decreased by 46.5%, 63.4%, and 69.2% respectively. Illumination had a greater effect on fat-soluble pigments than water-soluble pigments. Among the three temperature treatments, the contents of chlorophyll, carotenoid and anthocyanin were as follows:-20 ℃>4 ℃>room temperature, it is indicated that-20 ℃ was the best temperature to maintain the stability of pigment composition. The contents of chlorophyll a, chlorophyll b, β-carotene, lutein and zeaxanthin in the light samples decreased by 34.8%, 69.0%, 72.5%, 61.6%, 36.1%, respectively. After storage for 5 months, the contents of chlorophyll, carotenoid and anthocyanin constituent at-20 ℃ was significantly higher than those at 4 ℃ and room temperature. The results show that light avoiding and low-temperature can effectively slow down the degradation of pigment components. Therefore, it is suggested that D. catenatum flower should be stored in light avoiding and low-temperature conditions in actual production and processing, which can prolong the usable time.

RESUMO

To reveal the main nutrients and functional ingredients in the flowers of Polygonatum cyrtonema and P. filipes, the content of the polysaccharides, saponins, amino acids, total phenols, mineral elements, and the DPPH free radical scavenging rates were determined. The flowers and rhizomes of P. cyrtonema were collected from Qingyang in Anhui and Qingyuan in Zhejiang, while the flowers and rhizomes of P. filipes were collected from Longyou in Zhejiang, respectively. The results showed that the polysaccharides content in flowers varied from 60.88 to 97.00 mg·g~(-1), about half of that in rhizomes. The saponins content in flowers varied from 32.55 to 40.93 mg·g~(-1), which was close to the content in rhizomes. The content of total phenols ranged from 40.79 to 50.95 mg·g~(-1), approximately 4.5 times of that in rhizomes. The total amino acids content in flowers was 111.85 to 131.03 mg·g~(-1), about 2.3 times of the content in rhizomes. The essential trace element content was abundant in flowers. The contents of heavy metal elements were all within the limits set by the standards. The DPPH free radical scavenging rate IC_(50) varied from 1.77 to 3.25 mg·mL~(-1), less than one-fifth of that in rhizomes, showing a significant superiority of antioxidant activity compared to rhizomes. The results initially revealed the fundamental of "the flowers exceed the rhizomes in effect", the common saying about the traditional Chinese medicinal herbs over the years, indicating a great developing potential of the flowers. Besides, as polysaccharides, saponins, amino acids, total phenols and other nutritive substances in flowers differ widely among species and provenances, it's important to develop variety breeding to improve the quality and yield of flowers.

RESUMO

The non-starch polysaccharides,mainly composed of glucomannans,are the major bioactive compounds in Dendrobium catenatum. In order to evaluate the quality of the medicinal materials and guide the production and processing,a quantification method of non-starch polysaccharides was established by stems of D. catenatum C15 strain collected from the pear epiphytic cultivation. The non-starch polysaccharides were obtained by " water extraction,α-amylase pretreatment,and alcohol precipitation once" method. The contents of starches,non-starch polysaccharides and monosaccharides were analyzed. In addition,the system suitability was tested. Compared with method of the Chinese Pharmacopoeia( 2015 edition),the contents of total polysaccharides,glucose,and mannose were decreased by 20. 9%,58. 8% and 1. 6% respectively. The method effectively digested starch and retained non-starch polysaccharides,and the analysis result was accurate and repeatable. Therefore,it is suitable for the content measurement of non-starch polysaccharides of D. catenatum. Furthermore,it could be an alternative method for quality control of D. catenatum and a reference in the determination of non-starch polysaccharides in other starch-containing medicinal materials.

RESUMO

PURPOSE: Although the interferon α (IFNα) signaling and the paired-like homeodomain transcription factor 2 (PITX2) have both been implicated in the progression of breast cancer (BCa), it remains obscure whether these two pathways act in a coordinated manner. We therefore aimed to elucidate the expression and function of PITX2 during the pathogenesis of endocrine resistance in BCa. MATERIALS AND METHODS: PITX2 expression was assessed in BCa tissues using quantitative reverse transcription polymerase chain reaction (RT-qPCR) and immunohistochemistry and in experimentally induced letrozole-resistant BCa cells using RT-qPCR and immunoblotting. Effects of PITX2 deregulation on BCa progression was determined by assessing MTT, apoptosis and xenograft model. Finally, using multiple assays, the transcriptional regulation of interferon-inducible transmembrane protein 1 (IFITM1) by PITX2 was studied at both molecular and functional levels. RESULTS: PITX2 expression was induced in letrozole-resistant BCa tissues and cells, and PITX2 induction by IFNα signaling powerfully protected BCa cells against letrozole insult and potentiated letrozole-resistance. Mechanistically, PITX2 enhanced IFNα-induced AKT activation by transactivating the transcription of IFITM1, thus rendering BCa cells unresponsive to letrozoleelicited cell death. Additionally, ablation of IFITM1 expression using siRNA substantially abolished IFNα-elicited AKT phosphorylation, even in the presence of PITX2 overexpression, thus sensitizing BCa cells to letrozole treatment. CONCLUSION: These results demonstrate that constitutive upregulation of PITX2/IFITM1 cascade is an intrinsic adaptive mechanism during the pathogenesis of letrozole-resistance, and modulation of PITX2/IFITM1 level using different genetic and pharmacological means would thus have a novel therapeutic potential against letrozole resistance in BCa.

RESUMO

The study is aimed to fully analyze antioxidant activty and stability of color-related components from Dendrobium officinale flower. The contents of anthocyanins,carotenoids and flavonoids of 10 varieties including whole flower and labellum of D.officinale flower were detected using UV visible spectroscopy technique and evaluated for their 1,1-diphenyl-2-picrylhydrazyl radical (DPPH·), superoxide anion radical (·O⁻₂) and hydroxy radical (·OH) scavenging activty. And the effects of 4 kinds of metal ions (Cu²⁺, Mg²⁺, Al³⁺,K⁺) and 2 kinds of food additives were investigated on the stability of anthocyanins pigment from D.officinale flower. The results indicated that the flower of D.officinale contained anthocyanins,carotenoids and flavonoids,and their contents in different parts of different families varied. The content of anthocyanins (1 330.9 μg·g⁻¹) in labellum was significantly higher than that in the whole flower (696.3 μg·g⁻¹). The content of carotenoids was positively correlated with the content of anthocyanins,and there was significant positive correlation between the scavenging capacities of the three free radicals and the contents of anthocyanin,respectively (0.415,0.384,0.455). The Cu²⁺, Mg²⁺, Al³⁺, K⁺ and glucose showed significant color-enhancing effect and could increase the stability of anthocyanin in D.officinale flower,while ascorbic acids showed remarkably degradation effect of anthocyanin in D.officinale flower.

RESUMO

In order to provide new information on polysaccharide in Dendrobium officinale flowers,the monosaccharide composition and relative molecular mass distribution of 11 families of flowers were investigated and analyzed by high performance gel filtration chromatography (HPGFC) and pre-column derivatization ultra performance liquid chromatography (UPLC) in this study. Then cluster analysis was carried out for the monosaccharide peak areas by utilizing SPSS 19.0 software. The results showed that the polysaccharides of all the above 11 hybrid families of D. officinale flower were separated into three fractions (DOP-1, DOP-2 and DOP-3) with the average relative molecular mass of 5.53×105, 3.49×105 and 2.12×105. The polysaccharides in 11 different families were mainly composed of glucose, mannose, galactose, galacturonic acid and arabinose; mannose had the highest proportion among them, with mannose/glucose ratio of 0.302-3.335. Additionally, the relative contents of various monosaccharides in different families varied. 11 families of D. officinale flower could be classified into four categories according to their monosaccharide components and relative contents. In this study, the relative molecular mass distribution and monosaccharide composition of polysaccharides in D. officinale flowers were defined, which can provide foundations for its resource utilization..

RESUMO

The aim of the paper is to reveals the variations of Dendrobium officinale amino acids in different strains and parts for breeding excellent varieties, and providing scientific basis for the expanding of medicinal or edible parts. The contents of 17 amino acids in 11 strains of D. officinale were determined by hydrochloric acid hydrolysis method. The total amino acids content of leaves was from 6.76 to 7.97 g per 100 g, and the stems was from 1.61 to 2.44 g per 100 g. As the content of amino acids in leaves was significantly higher than that of stems, and the composition was close to the ideal protein standard proposed by FAO/WHO. The leaves of D. officinale had the good prospect for the development of functional foods. The 9 x 66 strain which with high yield and polysaccharide content had the highest amino acids content both in stems and leaves, indicated crossbreeding could improve the quality of varieties. Compared the amino acids content of D. officinale in two main harvest periods, the harvest time has a significant impact on amino acids content of D. officinale. This study demonstrates that the harvesting time of D. officinale stems is suitable for leaves as well, which is the period before bolssom.

RESUMO

This paper revealed the accumulation regularity of polysaccharides and alcohol-soluble extracts contents of Dendrobium officinale leaves, which have provided basis for the development and utilization of the leaves. The polysaccharides and alcohol-soluble extracts contents of three D. officinale strains leaves collected in different growing periods were determined by phenol-sulfric acid method and hot-dip method respectively. The results showed that the content of polysaccharides in leaves was 4.45% -12.17%, and was about a quarter in stems. The alcohol-soluble extracts content in leaves was 7.45% - 29.34%, and was 1.5 times that of stems. The quality variation of polysaccharides in leaves was closely related to the phenophase. The leaves with lower level of metabolism in three stages: winter, early germination stage and deciduous period, which led to lower content of polysaccharides. The leaves at the vigorous growth stage with higher content of polysaccharides. The alcohol-soluble extracts were closely associated to the formation and germination of buds. The content of alcohol-soluble extracts peaked before sprout, and promoted the growth of new shoots.
