Gen info
- Etymology: The genus name Xylocarpus derives from Latin meaning woody, referring to the large and distinctly woody fruit and seeds of the genus.
- The common name "puzzlenut tree" derives from the irregular shape of the seeds: a puzzle can be made shuffling the seeds and attempting to reassemble them in the original spherical arrangement. (53)

Botany
Piyagaw is a small tree growing 3 to 12 meters high. Leaves are abruptly pinnate, with pairs of leaflets which are elliptic or obovate, 8 to 18 centimeters long, 4 to 8 centimeters wide, with a pointed base and rounded tip. Flowers are small and white, 4-parted, borne on short terminal or axillary (upper) panicles. Fruit is spherical, 9 to 12 centimeters in diameter, with 6 to 12 seeds. Pericarp is hard and fibrous, splitting into 4 valves. Seeds are angled, with a spongy integument.

X. moluccensis is similar to Xylocarpus granatum (piyagaw). X. granatum has larger fruit, smooth, patchy bark, buttresses and plant-like aerial roots. X. moluccensis has a smaller fruit, with conical pneumatophores. (1)

α-glucosidase inhibition assay) and antioxidant (ABTS scavenging and metal chelating assay) activities of various extracts of leaves and bark extracts in STZ induced diabetic mice. Ethanol bark extracts (XGEB) showed higher in vitro a-amylase inhibition and ABTS scavenging activities. The XGEB treatment also resulted in significant decrease (p<0.05) in blood glucose, triglycerides, total cholesterol, SGOT, SGPT and urea levels. HPLC analysis revealed the presence of simple polyphenols, isoflavone, and flavonol-like compounds. Results demonstrated the beneficial effect of XGEB in controlling hyperglycemia and ameliorating oxidative stress associated diabetic complications. (32)

• Biological Activities of Limonoids, Catechins, Procyanidins / Bark:
Procyanidins and catechins were found in high amounts in a methanol bark extract of X. granatum. Catechins, procyanidins, limonoids, and plant extracts were evaluated for DPPH radical scavenging activity and 15-lipoxygenase (15-LO) inhibiting effects. Catechins and procyanidins exhibited high activity. Procyanidin of the pentamer type was most potent (DPPH IC50 3.3 ± 0.3 µM, 15-LO 0 ± 1 µM). Extracts were found to have antibacterial activity. (39)
• Silver Nanoparticles / Polysaccharide / Antimicrobial / Leaves:
Study reports on the green synthesis of silver nanoparticles using polysaccharide extracted from leaves of X. granatum. Polysaccharide-based metallic NPs have increasing commercial demand because of wide applicability such as electronics, chemistry, energy, cosmetics, and medicine. The polysaccharide acts as reducing and stabilizing agent. The synthesized NPs were very effective as antimicrobial agent against come important human pathogens such as E. coli, S. typhimurium, S. typhi. The NPs also showed sporicidal activity. The NPs can also reduce microbial load by decreasing microorganisms in sewage water. Effectiveness was compared with Cipran-500. (40)
• Gedunin / Limonoid /
Inhibition of CaCo-2 Colon Cancer Cell Line / Bark: Study yielded two limonoids from the bark of X. granatum, gedunin and 1a-hydroxy-1,2-dihydrogedunin. Traditionally, gedunin has been used as an astringent and febrifuge, and for treatment of fever, malaria, thrush, cholera, dysentery, and diarrhea. Study evaluated the cytotoxic potential of gedunin using CaCo-2 colon cancer cell line (IC50 = 16.83 µM). (43)
Gastroprotective / Antiulcer / Gedunin and Photogedunin / Anti-Secretory / Fruit: Study evaluated the gastroprotective mechanism of X. granatum fruit. A chloroform fraction (FrCHCl3) was evaluated against cold-restraint (CRU), aspirin (AS) alcohol (AL) and pyloric ligation (PL) induced gastric ulcer models in rats and histamine (HA) induced duodenal ulcer model in guinea pigs. Results showed potential anti-ulcer activity against CRU (58.28%), AS (67.81%), AL (84.38%), PL (65.66%) and HA (61.93%) induced ulcer models. Activity was compared to Omeprazole and Sucralfate.  Phytochemical study of FrCHCl3 yielded gedunin (36%) and photogedunin (2%). FrCHCl3, gedunin, and photogedunin significantly inhibited H+K+-ATPase activity in vitro with IC50s of 89.37, 56.86, and 66.54 µg/mL respectively, compared to omeprazole (30.24 µg/ml) confirming their antisecretory activity. (46)
Anticancer / Antioxidant / Leaves: Study of ethyl acetate extract of leaves yielded phenolic compounds and several organic and amino acids as byproducts, such as succinic acid and acetic acid. Traces of flavonoids and non-categorized phenolic compounds exhibited intermediate antioxidant activity (IC50 84.93 ppm) and anticancer activity against HeLa, T47D, and HT-29 cell lines. Fraction 5 showed strongest anticancer activity (IC50 23.12 ppm). (47)
Cipadesin A / Antidepressant: Study evaluated the potential antidepressant-like effects of cipadesin A,  a limonoids extracted from X. granatum, in acute stress-induced depression mouse models using forced-swimming test (FST), tail suspension test (TST), and open-field test (OFT). Results showed cipadesin A significantly reduced floating time in the FST and immobility time in TST. It dose-dependently increased the time in central zone in the OFT without alt3ring locomotor activity. Treatment significantly increased the levels of serum corticosterone and ACTH. The antidepressant-like effects occurred likely via inhibition of the HPA (hypothalamus-pituitary-adrenal) axis activity in response to stress. (48)
Burn Wound Healing / Antioxidant / Seeds: Study evaluated the effect of XG extract seed creams (10 and 15% concentration) on burn wound grade IIA in mice. Treatment with 15% cream promoted significant burn wound healing by increasing wound contraction rate, proliferation of fibroblasts, and re-epithelization. The XG extract also showed very strong antioxidant activity (IC50 7.939 ppm). (49)
Burn Wound Healing / Antioxidant / Fruit: Study evaluated lotions made of mangrove fruit extract (XG)  and a mixture of fruit extract and sodium alginate extract lotion as topical on incision cut wound on mice abdominal area. Results showed the XG extract lotion displayed significant antimicrobial activity against both pathogenic microbe species (Pseudomonas aeruginosa and Staphylococcus epidermis) and did not conflict with the antimicrobial activity found in the sodium alginate lotion. The mix of XG mangrove fruit and sodium alginate showed most potency in wound treatment. (50)
Gedunin / Antiproliferative in Ovarian Cancer Cells: Gedunin is a natural tetranoterpenoid secondary metabolite found in plants of the Meliaceae family, which has been reported for its anticancer activities. Study reported on the molecular mechanisms underlying the in vitro anti-proliferative activity of gedunin isolated from XG in human ovarian cancer cells. The gedunin triggered severe ROS generation leading to DNA damage and cell cycle arrest in G2/M phase thus inhibiting cell proliferation. ROS upregulation led to mitochondrial stress and membrane depolarization, which eventually resulted in mitochondria-mediated apoptosis. Gedunin is also an inhibitor of the evolutionarily conserved molecular chaperone Heat Shock Protein 90 (hsp90) responsible for maintaining cellular homeostasis, and targeting this chaperone can be an attractive strategy for developing cancer therapeutics. The study provides insights into the molecular mechanism of action of gedunin, which may aid drug development efforts against ovarian cancer. (52)
