Cultivar Sichompu shows higher inhibition of ROS formation as compared with cultivar Rongrien [42]. Cultivar Binjai poses greater ABTS antiradical activity though cultivar Aceh demonstrates higher activity in FRAP assay [48]. The bitter selection of N. lappaceum exhibits greater activity in all antioxidant assays tested when compared together with the sweet varieties [40]. This is since the phytochemical compositions are diverse in cultivars caused by environmental variables for example temperature, humidity, pH and nutrient in the soil that influence the metabolism of the plant and as a result impacts the secondary metabolite production. 4. Other Biological Activities of N. lappaceum four.1. Anti-Neoplastic Effects The YTX-465 Autophagy anti-proliferative effect of N. lappaceum peel extract has been tested on a cervical WZ8040 References cancer cell line (HeLa), breast cancer cell line (MDA-MB-231) and osteosarcoma cell line (MG-63) [50]. The study observed that both the red and yellow peels of N. lappaceum exhibited anti-proliferative effects on breast cancer cell lines and osteosarcoma cancer cell lines. The yellow peel extract of N. lappaceum showed a far better anti-proliferative effect around the breast cancer cell line (IC50 = 5.42 /mL) and osteosarcoma cell line (IC50 = six.97 /mL) as compared using the red peel extract. A recent study revealed that the anti-neoplastic effects of methanol peel extract effectively lowered HepG-2 cancer cell line viability by way of inducing apoptosis with DNA fragmentation and cell shrinkage. Phytochemical evaluation showed that the high antineoplastic effects of methanol peel extract had been contributed by the high phenolic contents which include coumarin, flavonoid, phenols, saponin and tannin. Other compounds, for example alkaloid, carbohydrate, cardiac glycoside, protein, terpenoid and triterpenoid, had been also detected in the methanol extract [47]. Even so, the anti-proliferative impact of peel and seed of your fruit tested on human mouth carcinoma cell line (CLS-354) showed that the peel (IC50 = 292 /mL) and seeds (IC50 = 305 /mL) didn’t show high anti-proliferative effects on the cancer cell lines [9]. A trypsin inhibitor extracted from the seed was discovered to exhibit a dose-dependent antitumour impact on breast cancer cell (MCF-7), HepG-2 and nasopharyngeal carcinoma cell lines (CNE-1 and CNE-2) [51]. Also, a 22.5-kDa trypsin inhibitor from N. lappaceum seeds has an inhibitory effect on HIV-1-reverse transcriptase activity and reduces theMolecules 2021, 26,8 ofproteolytic activities of trypsin at the same time as -chymotrypsin through disulphide bonds. The isolated trypsin inhibitor is one of the couple of inhibitors that will stimulate the production of nitric oxide, which acts as an anti-tumour molecule [51]. 4.2. Anti-Microbial The anti-microbial activities with the fruit against different microorganisms are shown in Table five. The development of Staphylococcus aureus is inhibited by peel extract [22,39,524]. Additionally, the growth of multi-drugs resistant Staphylococcus aureus (MRSA) can also be inhibited when treated with methanol peel extract (MIC = 0.4 mg/mL) [53] and ethanol peel extract (MIC= 0.98.95 mg/mL) [55]. Apart from that, the peel extract a.
