[Objectives]The anti-tumor activity of fractions from Buddleja officinalis Maxim.by petroleum ether,ethyl acetate,n-butanol and water solvent was studied.[Methods]The ethanol extract from B.officinalis Maxim.was extracted and then concentrated with petroleum ether,ethyl acetate,n-butanol and water,respectively,and the extracts were obtained.The inhibitory effects of the four different fractions on the growth of three tumor cell lines in vitro were detected by CCK-8 method,and the median inhibitory concentration(IC 50 value)was calculated.[Results]The four fractions inhibited the growth of the three tumor cell lines in vitro,among which the n-butanol fraction had the best anti-tumor activity.The IC 50 values of the n-butanol fraction on human gastric cancer(SGC-7901),human breast cancer(MCF-7)and human liver cancer(BEL-7404)cell lines were 0.08,1.58 and 0.12 mg/mL,respectively.[Conclusions]Petroleum ether,ethyl acetate,n-butanol and water fractions from the ethanol extract of B.officinalis Maxim.had certain anti-tumor effects,and the n-butanol fraction had the best anti-tumor activity. 展开更多

Buddleja macrostachya (Buddlejaceae) is a widespread shrub native to the Sino-Himalayan mountains and beyond. It has been found to occur at two ploidy levels, hexaploid, 2n=6x=114 and dodecaploid, 2n= 12x=228. To determine if morphological characters might be used as indicators of ploidy levels, we measured floral and fruit length, relative and absolute leaf size, trichome density on both leaf surfaces, and stomatal density and length in different populations orB. macrostachya. In general, flower and fruit length, absolute leaf size, and stomatal length in,eased with an increase at ploidy level (P〈0.01), whereas adaxial cell and stomatal density decreased with an increase at ploidy level (P〈0.01). We found no conspicuous differences in relative leaf size (P〉0.05) in different populations. Other characters studied such as trichome type, cuticular membrane and ornamentation of stomata, cell and stomatal shape, and anticlinal wall pattern were quite constant in this species. Thus it appears that flower and fruit length, absolute leaf size, and stomatal frequency and length can be used to distinguish hexaptoid from dodecaploid cytotypes either in the field or in herbarium specimens. 展开更多

Objective To observe the effects of Buddlejae Flos (Mi Meng Hua,密蒙花) granules on the expression of TGF-β1, NF-κB, IL-10 and IL-12 in lacrimal gland cells in castrated male rabbits. Methods A total of 30 New Zealand male white rabbits were randomly divided into 5 groups. Group A: blank group;group B: model group;group C: Buddlejae Flos (Mi Meng Hua,密蒙花) granules group;group D: placebo group;group E: testosterone group. Except for the group A, all rabbits were treated with bilateral testicular and epididymis resection before intervention. Rabbits in group C were administered with Buddlejae Flos (Mi Meng Hua,密蒙花) granules (100 mg/kg), 3 times per day;Rabbits in group D were administered with normal saline, 3 times per day. Rabbits in group E were injected with testosterone propionate (0.5 mL/kg) in the thigh muscle, every 3 days. Schirmer I test (SIT) and break-up time (BUT) were measured on 1st day before modeling and 30th day after modeling. After 30 days of intervention, all rabbits were sacrificed. The removal lacrimal gland was stained in immunohistochemica staining. The expression of TGF-β1, NF-κB, IL-10 and IL-12 in lacrimal gland tissue of each group was detected, and the structure of lacrimal gland was observed. Results The results of SIT and BUT showed that there was significant difference between group B and D compared with group A (P < 0.05). There were no significant differences between group C and E (P > 0.05). There were no significant differences in the comparison of inflammatory factors TGF-β1, NF-κB, IL-10 and IL-12 between group B and D (P > 0.05). There were significant differences between group B and D compared with other groups (P < 0.01). There was no significant difference between group A, C and E (P > 0.05). Conclusions Buddlejae Flos (Mi Meng Hua,密蒙花) granules have an inhibitory effect on the expression of TGF-β1, NF-κB, IL-10 and IL-12 in castrated male rabbit lacrimal gland cells, and alleviate the inflammation of lacrimal gland tissue by inhibiting the expression of TGF-β1, NF-κB, IL-10 and IL-12 in lacrimal gland tissue, so as to treat dry eye. 展开更多

无柄醉鱼草(Buddleja sessilifolia)是狭域分布的极小种群野生植物(Plant Species with Extremely Small Populations,PSESP),大叶醉鱼草(B.davidii)则是广布种,二者亲缘关系较近,且同为四倍体。通过比较濒危物种与近缘广布种的遗传多样... 无柄醉鱼草(Buddleja sessilifolia)是狭域分布的极小种群野生植物(Plant Species with Extremely Small Populations,PSESP),大叶醉鱼草(B.davidii)则是广布种,二者亲缘关系较近,且同为四倍体。通过比较濒危物种与近缘广布种的遗传多样性,可以了解濒危物种的演化历史,为制定保护策略提供理论依据。本研究通过简单重复序列(Simple Sequence Repeats,SSR)分子标记对无柄醉鱼草5个居群(126个个体)和大叶醉鱼草14个居群(206个个体)进行遗传多样性和遗传结构解析,并提出对无柄醉鱼草的保护建议。结果表明,无柄醉鱼草和大叶醉鱼草各居群的期望杂合度(He)平均值分别为0.606、0.775,Shannon′s多样性指数(I)平均值分别为1.162、1.729,两个物种均具有较高的遗传多样性,但广布种大叶醉鱼草遗传多样性水平高于狭域种无柄醉鱼草;无柄醉鱼草和大叶醉鱼草遗传分化系数(F ST)分别为0.043和0.024,两个物种居群间遗传分化程度均较低。遗传结构分析结果表明,无柄醉鱼草5个居群可划分为2个集群,居群间地理距离与遗传距离不存在相关性;大叶醉鱼草14个居群可划分为3个集群,居群间地理距离与遗传距离相关。结合野外居群现状,建议对无柄醉鱼草划分保护单元,重点对丹珠居群和独龙江隧道口居群开展就地保护,同时采取种质资源收集、人工繁育等保护措施。 展开更多
