Conservation Of Symphytum Officinale L. At Cmprh Garden, Emerald

Symphytum L. commonly called as comfrey, belongs to the family Boraginaceae. The genus of Symphytum L. have a great medicinal value and used to treat a wide variety of ailments viz., bronchial problems, sprains, broken bones, arthritis, acne and skin conditions whereas pharmacological effects of comfrey extracts are endorsed to several chemical compounds. In view of above point, the present study of Survey, Collection and Documentation of Symphytum species, were carried out in different places of India. The rhizomes of Symphytum species were collected from Mynala village of Nilgiris, subsequent survey were carried out to IIIM Chatha Research Farm Jammu Tawi during 2017-2018 and it was grown at CMPRH garden, Emerald to confirm the identification of plants species. This specimen was collected and preserved herbarium at CMPRH garden Emerald for future reference. Among plants parts roots and leaves are mostly used for homeopathic system of medicine and this species were maintained and reproduces subsequent year by seed and root fragments. Root cuttings are the least expensive method of propagation. In addition to that Performance of Symphytum officinale at Nilgiris conditions were observed and the results revealed that Symphytum officinale L. is an erect, perennial herb with thick root stock. Leaves oblong-lanceolate and flowers are blue in colour. The data on length of root ranged from 10-20 cm with black to brown colour. Similarly, the length of lower, middle and upper cauline leaves ranged from 32.3-37.2 cm, 25.2-27.8cm, 10.4- 13.2cm, respectively Whereas the width of the lower, middle, upper leaves ranged 12.5-17.4 cm , 7.6- 10.2cm , 3.4-4.1cm, respectively. Further, the studies on Symphytum officnale regarding root yield, dry matter ratio of leaves and roots as well as physiochemical properties other chemical compounds present and uses in homoeopathic system of the medicine under the Nilgiris condition are need to be studied elaborately in future.

Corolla Abscission Triggered by Nectar Robbers Positively Affects Reproduction by Enhancing Self-Pollination in Symphytum officinale (Boraginaceae)

Nectar robbers, which affect plant fitness (directly or indirectly) in different degrees and in different ways, potentially constitute a significant part of mutualistic relationships. While the negative effects of nectar robbing on plant reproductive success have been widely reported, the positive effects remain unknown. The target of our study was to evaluate the effects of nectar robbers on the reproductive success of Symphytum officinale (Boraginaceae). We observed the behavior, species and times of visitors in the field, and we assessed the effect of nectar robbers on corolla abscission rate and time. To test the fitness of corolla abscission, we detected the changes in stigma receptivity, pollen viability, pollen amount and appendage opening size along with the time of flower blossom. The flowering dynamics and floral structure were observed to reveal the mechanism of self-pollination. Finally, pollen deposition seed set rate and fruit set rate were determined to estimate the effect of nectar robbers on reproduction success. We observed 14 species of visitors and 2539 visits in 50 h of observation; 91.7% of them were nectar robbers. The pressure and nectar removal of nectar robbers significantly promoted corolla abscission during a period when pollen grains are viable and the stigma is receptive. In addition, corolla abscission significantly increased the pollen deposition and seed setting rate. Our results demonstrate that nectar robbing contributes to enhancing seed production and positively and indirectly impacts the reproductive success of S. officinale. This mechanism involved the movement of anthers and indirect participation by nectar robbers, which was rarely investigated. Considering the multiple consequences of nectar robbing, understanding the impact of nectar robbers on plant reproduction is essential to comprehend the evolutionary importance of relationships between plants and their visitors.

Allantoin from Valuable Romanian Animal and Plant Sources with Promising Anti-Inflammatory Activity as a Nutricosmetic Ingredient

Helix aspersa (HA), Helix pomatia (HP) and Symphytum officinale are common organisms in Romania’s biosphere, widely known for their allantoin content and their therapeutic properties. Herein, the allantoin was separated and quantified from the aqueous extracts of Romanian comfrey root and the secretions of HA and HP snails. This study also focused on determining the antioxidant and anti-inflammatory activities of these Romanian allantoin-rich samples. The plant extracts were obtained through two methods: ultrasonic extraction and enzymatic ultrasonic extraction. A microplate method was used for the quantitative determination of allantoin content. The antioxidant activity was measured by using the DPPH radical scavenging method. The antioxidant capacity of the samples was studied in order to observe the type of interactions generated by the chemical complex present in their composition. High concentrations of allantoin were obtained by enzymatic ultrasonic extraction method (EUE—102 ± 0.74 μg/mL), and also in the water-soluble fraction of the snail secretion (FS1—22.051 μg/mL). The antioxidant screening suggests that Symphytum officinale and snail mucus extracts could be used as promising natural substitutes for synthetic antioxidants in products used for therapeutic purposes. The evaluation of anti-inflammatory activity was also investigated, allantoin-rich samples showing a promising action (FS1—81.87 ± 2.34%). In future, the inclusion of allantoin-rich extracts in various novel pharmaceutical forms for new therapeutic applications could be achieved. The study will continue with the formulation of a nutricosmetic product with snail mucus and Symphytum officinale extract as principal bioactive ingredients.

Influence of the Post-Harvest Storage Time on the Multi-Biological Potential, Phenolic and Pyrrolizidine Alkaloid Content of Comfrey (Symphytum officinale L.) Roots Collected from Different European Regions

Comfrey (Symphytum officinale L.) roots are well-known bioactive ingredients included in various cosmeceutical and pharmaceutical preparations. In this study, the influence of the post-harvest storage on the chemico-biological potential of roots collected from different European regions and stored for up to six months was investigated. Total phenolic content (TPC) and total phenolic acid content (TPAC) were spectrophotometrically estimated, whereas the levels of individual phenolic and pyrrolizidine alkaloidal markers were determined by HPLC-DAD and HPLC-MS/MS, respectively. The changes in the biological potential was tracked via antioxidant (DPPH, ABTS, CUPRAC, and FRAP) and anti-enzymatic (cholinesterase, tyrosinase, glucosidase, and amylase) assays. TPC and TPAC varied from 6.48–16.57 mg GAE/g d.w. root and from 2.67–9.03 mg CAE/g, respectively. The concentration of the four phenolics (rosmarinic acid, globoidnan A, globoidnan B, rabdosiin) and six pyrrolizidine alkaloids generally showed maximum values at 1–3 months, after which their levels significantly decreased. With respect to the bioassays, the samples showed a wide range of antioxidant and anti-enzymatic effects; however, a direct storage time–bioactivity relationship was not observed. Similar conclusions were also revealed by the multivariate and correlation analyses. Our study could improve the current knowledge of the shelf-life properties of comfrey-based products and enhance their industrial exploitation.

Experimental study the anti-inflammatory and osteo-regenerative qualities of the paste based on symphytum officinale tincture and calcium hydroxide

Replacement of the damaged bone remains actual and is far from being completely solved nowadays, despite its centuries-old history. The purpose of study was to investigate the anti-inflammatory and osteo-regenerative qualities of the paste based on Symphytum officinale tincture and calcium hydroxide in treatment on teeth with chronic granulating apical periodontitis in children and in an experiment on animals. Performed morphological and densitometric studies showed that remodeling of bone injury of the lower jaw in rats occurs almost equally in both experimental and control groups, and a paste based on Symphytum officinale tincture and calcium hydroxide also promotes bone regeneration at the defect site and stimulates osteosynthesis. Analysis of liver tissue, soft and hard tissues of the lower jaw in animals suggest that the proposed paste does not produce any toxic effect and provides significant anti-inflammatory properties. The gained result provide grounds to recommend the developed paste for therapeutic use in children as a temporary root canal sealing material in permanent teeth with granulating apical periodontitis.
