Background: Selliera radicans was recognized as one of the foods consumed by the oldest human settlement in America (Monte Verde, Chile) that had a diet with a high component of plants. Objective: This study aims at investigating nutritional and functional characteristics of S. radicans, a native halophyte from Chile. Materials and Methods: An analysis of total protein, carbohydrate, ash, and moisture from S. radicans leaves was performed, using standard methods. The content of macro and micronutrients was quantified by atomic absorption spectrometry. The inulin content was carried out based on the Seliwanoff reactions. S. radicans leaves were extracted with methanol and the total content of phenolic and flavonoids and antioxidant activity were evaluated by spectroscopic method. Results: Leaves from cultivated plants proved to be a suitable source of proteins (7.5 \% on DW), ash (6.8 \% on DW), and a wide range of macro and micronutrients, where Ca, K, and Na had the highest values. In addition, inulin (2.3\% on DW), total phenolics (63.4 GAE/g LDW) and flavonoids (21.8 QE/g LDW), and antioxidant capacity (10 TE/g LDW) were noted. Conclusions: According to the results, cultivated S. radicans leaves are promising sources of food with beneficial health properties.

Bryophyllum pinnatum is a perennial herb used in traditional medicine against varieties of ailments such as memory disorder. This study quantitatively estimated the total phenolic (TPC), total flavonoid (TFC) and total proautocyanidin (TPA) contents of extract and fractions of B. pinnatum and correlated them with its antioxidant and anticholinesterase activities. Methanolic extract of the dried leaves was partitioned into n-hexane, ethyl acetate and aqueous fractions. Total phenolic, flavonoids and proanthocyanidins content were estimated as gallic acid or quercetin equivalents. DPPH and nitric oxide scavenging activity as well as ferric reducing power assays were used to evaluate antioxidant activity, using 2,6-di-tert-butyl- 4-methylphenol (DDM) and ascorbic acid as standards. In vitro anticholinesterase activity was evaluated by Ellmann{\textquoteright}s colorimetry assay with phsiostigmine (serine) and donepezil as positive control. The crude methanol extract had the highest phenolic, flavonoid and tannin content. The ethyl acetate fraction had the highest DPPH radical scavenging effect (IC50 0.004 mg/ml) while the aqueous fraction had the highest NO scavenging and ferric reducing effects with values of IC50 0.012 mg/ml and 0.007 mg/ml respectively. The ethyl acetate fraction had the best cholinesterase inhibitory effect (IC50 0.951 μg/ml AChE; 3.546 μg/ml BuChE). DPPH radical scavenging effect correlated strongly with total phenolic, flavonoids and proautocyanidins (r2 0.896, 0.651 and 0.619 respectively) while ferric reducing power showed weak correlation and NO scavenging as well as AChE inhibition had no correlation. The study shows DPPH radical scavenging could be due to the phenolic content while other class of compounds are responsible for the cholinesterase inhibition.
