Smoke Water

Although treatments of smoke-water (SW) have been successfully used for promoting seed germination as well as plant growth, less reports have been documented on the influence of SW on the production of secondary metabolites in endophytes isolated from medicinal plants. The study investigated the effects of SW and its active compound butenolide (KAR1) on the accumulation of lipophilic tanshinones in endophyte Trichoderma atroviride D16 isolated from Salvia miltiorrhiza. Results showed that the mycelia of T. atroviride D16 treated with SW and KAR1 displayed a significant increase (P < 0.05) in the content of tanshinone I, which was evaluated with 2.26-fold (SW) and 1.86-fold (KAR1) of the control on 20 d after treatment. Comparing with the control, the treatment of SW and KAR1 resulted in a significant increase in the content of tanshinone IIA, and the highest levels were observed to be 31.87% (SW 1:2000, v/v) and 17.77% (KAR1 at 10-9 M) on 20 d after treatment. These findings imply the possibility of using SW and KAR1 for enhancing the biosynthesis of tanshinones in T. atroviride D16, and enrich the application of smoke water in the medicinal plant field.

Beneficial interactions between endophytes and plants are critical for plant growth and metabolite accumulation. Nevertheless, the secondary metabolites controlling the feedback between the host plant and the endophytic microbial community remain elusive in medicinal plants. In this report, we demonstrate that plant-derived triterpenoids predominantly promote the growth of endophytic bacteria and fungi, which in turn promote host plant growth and secondary metabolite productions. From culturable bacterial and fungal microbial strains isolated from the medicinal plant Schisandra sphenanthera, through triterpenoid-mediated screens, we constructed six synthetic communities (SynComs). By using a binary interaction method in plates, we revealed that triterpenoid-promoted bacterial and fungal strains (TPB and TPF) played more positive roles in the microbial community. The functional screening of representative strains suggested that TPB and TPF provide more beneficial abilities to the host. Moreover, pot experiments in a sterilized system further demonstrated that TPB and TPF play important roles in host growth and metabolite accumulation. In summary, these experiments revealed a role of triterpenoids in endophytic microbiome assembly and indicated a strategy for constructing SynComs on the basis of the screening of secondary metabolites, in which bacteria and fungi join forces to promote plant health. These findings may open new avenues towards the breeding of high yielding and high metabolite-accumulating medicinal plants by exploiting their interaction with beneficial endophytes.

Talinum paniculatum Gaertn. is one of traditional medicinal plant in Indonesia which has benefits such as for vitality and maintain blood circulation. The aim of this research is to obtain biomass production of root and shoot of T. paniculatum Gaertn. by liquid and solid MS medium with IBA. This research conducted to provide biomass as raw material for secondary metabolites test. Stems as explant were induced with four treatments (liquid MS, solid MS, liquid MS + 2 ppm IBA and solid MS + 2 ppm IBA) with five repetitions. Observation did for 28 days. The parameters are the percentage of explants which formed the root and shoot, morphology, fresh and dry biomass. Result shows that percentage of root and shoot have 100% in liquid and solid MS + 2 ppm IBA. Fresh and dry biomass of root and shoot in solid MS + 2 ppm IBA higher than the others. This research found callus in liquid and solid MS + 2 ppm IBA. Morphology of root in liquid MS has thin and friable, but thick in solid MS. Shoot in solid and liquid MS has thin, short and sturdy.

Drug Candidates

Biologically active molecules obtained from plant sources, mostly including secondary metabolites, have been considered to be of immense value with respect to the treatment of various human diseases. However, some inevitable limitations associated with these secondary metabolites like high cytotoxicity, low bioavailability, poor absorption, low abundance, improper metabolism, etc., have forced the scientific community to explore medicinal plants for alternate biologically active molecules. In this context, therapeutically active proteins/peptides from medicinal plants have been promoted as a promising therapeutic intervention for various human diseases. A large number of proteins isolated from the medicinal plants have been shown to exhibit anti-microbial, anti-oxidant, anti-HIV, anticancerous, ribosome-inactivating and neuro-modulatory activities. Moreover, with advanced technological developments in the medicinal plant research, medicinal plant proteins such as Bowman-Birk protease inhibitor and Mistletoe Lectin-I are presently under clinical trials against prostate cancer, oral carcinomas and malignant melanoma. Despite these developments and proteins being potential drug candidates, to date, not a single systematic review article has documented the therapeutical potential of the available biologically active medicinal plant proteome. The present article was therefore designed to describe the current status of the therapeutically active medicinal plant proteins/peptides vis-à-vis their potential as future protein-based drugs for various human diseases. Future insights in this direction have also been highlighted.

Johar (<em>Cassia seamea</em>) is a medicinal plant with a cassiarin A compound to combat malaria and has a low Cassiarin A is an active compound in Johar (<em>Cassia seamea</em>) medicinal plant capable of combating malaria, despite showing a low seed production rate due to dormancy. This inactivity is severed using gibberellic acid (GA<sub>3</sub>) treatments. This study aims to determine the effects of concentration and soaking period of GA<sub>3</sub> on seed germination and growth of Johar seedlings. A completely randomized design (CRD), consisting of 2 treatments was applied as the research method. The first treatment employed GA<sub>3</sub> concentrations of 0, 45, 90 and 135 ppm, while the second was based on the soaking interval at 6, 12, 18 and 24 hours. The results showed the capacity of GA<sub>3</sub> able to shatter the seed dormancy with percentage germination of 43.03% and a concentration of 50.28 ppm. Therefore, the interaction of the two treatments significantly influenced the growth of Johar seedlings. Consequently, the concentration of GA<sub>3</sub> at 79.89 ppm increased the root length to 52.19 cm, while 84.68 ppm produced a total of 20.91 roots, after a 6 hour soaking. In addition, the 96.67 ppm expanded the stem diameter by 0.93 cm.

In this report, 40 antidysenteric medicinal plant species representing 24 families were considered for qualitative assessment of their secondary metabolites like alkaloids, flavonoids, glycosides, sterols and tannins. Alkaloids were present in all plant species, though in different degrees and the relative effectiveness of Dragendorffs’ reagent was better than others. Distribution of flavonoids, glycosides, sterols and tannins was sporadic in different plant species except A. cepa, A. marmelos, I. coccinea, M. indica, S. dulcis and Z. officinale, where all these metabolites were present. Abundance and mode of distribution of secondary metabolites in different test plants and their organs were discussed. DOI: http://dx.doi.org/10.3329/jasbs.v39i2.17850 J. Asiat. Soc.

Medicinal plant products are characterized by the presence of several bioactive (primary and secondary metabolites) constituents that are present. Phytochemical (qualitative and quantitative analysis) and immunopharmacological based studies may provide new compounds in the form of drugs for eliminating intracellular as well as extracellular infections. Several immunopharmacological based reports have shown the action of medicinal plant products and its constituents (i.e. primary and secondary metabolites) against various pathogens i.e. cancer, inflammation, diabetes etc.
