“…Leaf calcium amount was 1.79 g/100g and the petiole showed 0.98 g/100g diverging the values reported in the literature; Oliveira et al (2012) found lower values of calcium in fresh (0.27 g/100g) and cooked leaves (0.37 g/100g), while Pinto et al (1999Pinto et al ( , 2001b obtained 2.23 g/100g with the raw leaf and 1.54 g/100g with the petiole. Taioba calcium amount indicates that the species is an important source of the mineral and can be used as dietary or therapeutic supplement in the prevention and treatment of osteoporosis (Oliveira et al, 2012).…”

“…Calcium oxalate acts as a protection factor of the plant against herbivory, and the petiole can serve as a reserve of that substance (Saito and Lima, 2009). One way to reduce the quantity of oxalate is by cooking (Oliveira et al, 2012;Lima and Krupek, 2016;Liu et al, 2018) since calcium oxalate is soluble in water and migrates during cooking to the water, reducing its content by leaching and making the leaves of Taioba a safe food for consumption (Seganfredo et al, 2001).…”

Taioba or Cocoyam - Xanthosoma sagittifolium (L.) Schott - leaves and petioles consumption is almost restricted to Brazilian traditional communities because the lack of knowledge about their chemical and nutritional features. This study was carried out to determine the Taioba leaves and petioles chemical properties (moisture, fixed mineral residue, Calcium, Magnesium, proteins, lipids, dietary fiber and carbohydrates) were quantified; Calcium oxalate was evaluated as an anti-nutritional factor. Bioactive compounds (vitamin C, chlorophyll, carotenoids, lycopene and phenolic compounds) were also determined. Antioxidant capacity was evaluated by DPPH and ABTS methods. Taioba leaves and petioles present greater quantity of proteins, fibers, Calcium, Magnesium and vitamin C than some conventional plants used as salad. The amount of Calcium oxalate was not considered harmful to human consume. Antioxidant activity related to Taioba bioactive compounds has functional and nutraceutical abilities, which opens promising prospects for its use.

“…A study from Cameroon confirmed that the plant was used against 'low calcium' (Jiofack et al, 2010). The free calcium concentration of the dry leaves was 638 mg/100 g (Oliveira et al, 2012), which means that the free calcium in the L. aestuans material in the high dose of 1.332 g is 8 mg, which cannot explain the improved antacid effect of the combined plant material and CaCO 3 .…”

The journal implements double-blind peer review practiced by specially invited international editorial board members. Objective: To examine the analgesic and anti-inflammatory activities of Xanthosoma sagittifolium L. (X. sagittifolium) leaves. Methods: The fresh leaves of X. sagittifolium were extracted with methanol followed by fractionation using ethyl acetate fraction (EAF), n-hexane fraction, chloroform fraction and aqueous fraction. The analgesic activity was determined by acetic acid-induced writhing test and tail immersion test using Swiss albino male mice. Carrageenan-induced paw edema test was used to resolve the anti-inflammatory activity using Wistar albino male rats. Results: The results displayed that among these four samples, EAF had maximum analgesic efficacy (P < 0.001) measured by acetic acid-induced writhing test (71.37%). In case of tail immersion test, EAF also exerted maximum activity (5.03 s, P < 0.001) at 180 min compared to n-hexane fraction, chloroform fraction and aqueous fraction at maximum concentration. In case of anti-inflammatory test, EAF remained ascendancy in its activity (P < 0.001) and it inhibited 72.92% of paw edema at maximum concentration at 180 min with respect to remaining fractions. Conclusions: The above evidences suggest that EAF of X. sagittifolium leaves is a potential source of natural compounds having analgesic and anti-inflammatory activities.
