Berberis lyceum Royle has such pronounced medicinal values that it is used as cure of many diseases and has exhibited great therapeutic effects among the local communities throughout the world. The present research was carried out to evaluate the quantitative ethnobotanical status and phytochemical analysis of B. lyceum. Regular field trips were arranged to the study area (Shangla District) in August 2017 to October 2019 and interviews with 100 residents (age range: 30 to 50 years) were conducted. The approach adopted for ethnobotanical data was semi-scientific as the inhabitants were not aware about the modern names of some diseases and therefore physician prescriptions were also consulted. Ethnobotanical data were examined using relative frequency of citation and % use value. The % use value of B. lyceum indicates that the people of District Shangla mostly used it for curing of different diseases. In spite of tremendous uses the plant still survived in this area mainly due to the non-accessibility for humans of the mountain tops; otherwise, increase in anthropogenic activities even in these hilly areas poses a threat of the eradication of this plant. To correlate the folkloric uses with its phytochemical composition, HPLC (high performance liquid chromatography) analysis was performed and a total of six phenolic compounds (quercetin, chlorogenic acid, berberine, rutin, mandellic acid, and hydroxy benzoic acid) were identified in its root. As most of the health complications are correlated to oxidative stress therefore in vitro antioxidant activity were also performed using DPPH (2, 2- diphenyl-1-picrylhydrazyl) and ABTS (2, 2′-azinobis-3-ethyl benzo thiazoline -6- sulfonic acid) assays. The observed antioxidant potential may most probably be due to berberine and chlorogenic acid that were present in highest concentration in the analyzed extract. The effectiveness of the selected plant as remedy for a number of diseases (that were pointed out by the local community) may be due to its phytochemical composition especially berberine and chlorogenic acid as oxidative stress is the root cause of many diseases. The plant extract exhibited high antioxidant potential (DPPH IC50 = 165µg/mL; ABTSIC50 = 110µg/mL) in relation to the detected concentration of berberine and chlorogenic acid. It can be inferred from experimental results that the ethnopharmacological efficacy of this endangered species may be due to its phytochemical composition and antioxidant activities. This case study helps to revive the importance of B. lyceum in local communities and emphasizes the need for its conservation.

Neurobiological activity of the methanol extracts of thirteen Umbelliferae (Apiaceae) plants was tested against acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and tyrosinase (TYR) using high-throughput screening technique. Although the extracts displayed none to low profile of inhibition against enzymes, the highest cholinesterase inhibition was observed with Heracleum platytaenium (32.52 ? 3.27 % for AChE and 46.16 ? 1.42 % for BChE) at 100 ?g mL-1. Since neurodegeneration is linked to oxidative damage, antioxidant potential of the extracts was searched through radical scavenging, metal-chelating capacity, and reducing power experiments and exerted modest levels of activity varying according to the method. The extracts had a better ability to scavenge nitric oxide radical (19.47 ? 2.09 % to 54.91 ? 1.98 %). Since these species are known to be rich in coumarins, our quantitative high-performance liquid chroatography (HPLC) analysis indicated presence of xanthotoxin, angelicin, isopimpinellin, bergapten, and pimpinellin in Heracleum platytaenium and angelicin and imperatorin in Angelica sylvestris var. sylvestris.

Grecian juniper (Juniperus excelsa M. Bieb.) is an evergreen tree and a rare plant found in very few locations in southern Bulgaria. The aim of this study was to evaluate the phytochemical content and antioxidant potential of J. excelsa unripe and ripe galbuli from three different locations in Bulgaria. The essential oil content ranged between 1.9% and 5.1%, while the lipid fraction yield was between 4.5% and 9.1%. The content of total chlorophyll was 185.4–273.4 μg/g dw. The total carotenoid content ranged between 41.7 and 50.4 μg/g dw of ripe galbuli, and protein content was between 13.6% and 16.4%. Histidine (5.5 and 8.0 mg/g content range) and lysine (4.0 and 6.1 mg/g) were the major essential amino acids. The antioxidant potential of the 95% and 70% ethanol extracts was analyzed using four different methods. A positive correlation between the antioxidant potential and phenolic content of the galbuli was found. The results obtained in this study demonstrated the differences in phytochemical composition and antioxidant capacity of J. excelsa galbuli as a function of maturity stage and collection locality.
