OBJECTIVEDiscuss the trade-off between vegetative growth and reproductive growth.

METHODVegetative modules and reproductive modules by large sampling were separated and quantitative charecters of organs and pattern of reproductive allocation were analysed of reproductive allocation were analysed.

RESULTThe phenotype plasticity of quantitative charecters were significant. Reproductive biomass was increasing at different stages. The mass of reproductive investment increased significantly with increasing individual size, the opposite of reproductive allocation. There were all significant positive correlations between the seeds weight and height, total biomass, vegetative biomass, reproductive biomass, fruit numbers, fruit weight.

CONCLUSIONThe significance of phenotype plasticity is the cause of multiple elements. In the process of transferring from vegetative growth to reproductive growth, there was a trade-off between organs. Under individual growth and reproductive strategy, the variation of biomass was allocated coordinately.

Several Orobanche medicinal plants sometimes served as alternative sources of Cistanches Herba, attributing to the benefits such as tonifying kidney, strengthening tendons and bones. Among them, O. coerulescens, O. cernua and O. pycnostachya have been widely utilized in northern China for treatments of pains in the loins and knees, impotence, and spermatorrhea. However, their chemical profiles haven't been elucidated. In the present study, UHPLC-IT-TOF-MS was implemented to conduct in-depth chemome profiling of O. coerulescens, O. cernua and O. pycnostachya, aiming to achieve a comprehensive chemical characterization and to provide pronounced information for the quality control and clinical applications. An ACE Ultra-Core 2.5 Super C_(18)(3.0 mm×150 mm, 2.5 μm) column was deployed for chromatographic separations, and high-resolution MS~n spectra were recorded by IT-TOF-MS. Forty-eight components, in total, were observed, and thirty-eight ones were structurally annotated according to proposing mass fragmentation patterns, matching with relevant databases. Particularly, nine ones were confirmed by reference compounds. Overall, the chemical compositions of O. coerulescens and O. cernua are quite similar, and differences occur between O. pycnostachya and the prior two ones; primary chemical family is phenylethanoid glycosides, and several lignan glycosides as well as iridoid glycosides are also observed; the primary components include acteoside, isoacteoside, crenatoside and 2'-acetylacteoside, etc.

Cistanches Herba(CH), a valuable medicinal material which has long been used, originated from Shennong's Classic of Materia Medica. It has a wealth of names, such as Rousongrong, Heisiming, Dijing, and Dayun. The definition on the original plants which are parasitic and distributed in the unique environments in remote areas has been confusing, resulting in the emergence of various counterfeits and substitutes. Moreover, the records on the property, flavor, tropism, and indications of CH are also different. In order to further explore the cultural connotation and medicinal value of CH and further clarify its source and harvesting and processing methods, this study conducted further classical literature research on its name, harvesting and processing, property and flavor, meridian tropism, efficacy and clinical use, and textual research on its source and habitats, providing a reference for research, clinical medication, development and utilization, and industry development of CH.

Cistanche tubulosa and Laminaria japonica have been reported to have anti-oxidative, anticoagulant, anti-cancer and anti-inflammatory properties. They are expected to be a promising candidates for promoting hair growth and treating dandruff and scalp inflammation as a consequence. In this double-blinded, placebo-controlled clinical trial, we investigated the efficacy of Cistanche tubulosa extract and Laminaria japonica extract complex (MK-R7) in promoting hair health in patients with mild to moderate patterned hair loss. Using phototrichogram (Folliscope 4.0, LeadM, Seoul, Korea), we compared the density and diameter of hairs in patients receiving a placebo or Cistanche tubulosa extract and Laminaria japonica extract complex (MK-R7) at baseline, 8 and 16 weeks of the study. In order to determine the efficacy of treatment on dandruff and scalp inflammation, investigator's assessment score and patient's subjective score were also performed. We found a statistically significant increase in the hair density of the test group (n = 45, MK-R7 400 mg) after 16 weeks of consuming the MK-R7 (test group: 23.29 n/cm2 +/- 24.26, control: 10.35 n/cm2 +/- 20.08, p < 0.05). In addition, we found a statistically significant increase in hair diameter in the test group compared to control group at week 16 (test group: 0.018 mm +/- 0.015, control: 0.003 mm +/- 0.013, p < 0.05). There were also significant outcomes regarding the investigator's visual assessment and patient's subjective score of dandruff and scalp inflammation in the test group compared to those in control group. Based on the results of this clinical study, we conclude that Cistanche tubulosa extract and Laminaria japonica extract complex (MK-R7) are promising substances for promoting health of the scalp and hair.

In this study, taking Cistanche deserticola in Xinjiang as the experimental material, the optimal process for extracting polysaccharides from C. deserticola with water extraction was studied by using single factor and orthogonal experiment. Its effects on protein removal and polysaccharides retaining were investigated by using Sevag, enzymatic method or combination of these two methods, so as to determine the optimal method for protein removal from polysaccharides of C. deserticola; the decolorization and purification methods such as macroporous resin of AB-8 and activated Carbon were used to determine the optimal process. The results showed that the extraction rate of polysaccharides from C. deserticola was 18.40% during the optimal process of the water extraction as follows: extraction temperature 75 ℃, extraction time 165 min and solid-liquid ratio 1∶55. The protein removal rate can reach 31.40% and polysaccharide retention rate can reach 96.00% under the optimal protein removal process: temperature 50 ℃, time 2 h, and papain dosage 0.2%. The decolorization rate of activated Carbon and macroporous resin called AB-8 was 80.37% and 86.43%, and the recovery rate of polysaccharides was 77.05% and 91.93%, respectively, suggesting that macroporous resin was more suitable for decoloration. Macroporous resin named AB-8 increased the purity of the polysaccharide crude extract from 67.70% to 84.80% under the following conditions: concentration of the sample 4 g·L~(-1), concentration of the eluent 60% ethanol, and the flow rate 1 mL·min~(-1), showing significant purification effect.
