https://updatepublishing.com/journal/index.php/jp/article/view/9091
<p>This study aimed to determine the survival, sprouting, and rooting performance of black pepper stem cuttings to glucose, sucrose, and fructose at different concentrations. The two-node stem cuttings were prepared from six to seven-node cuttings collected from mother vines of black pepper in the field from far and remote areas in Sarawak, Malaysia. The two-node cuttings were soaked completely for one hour with the following treatments: 1% glucose, 2% glucose, 3% glucose, 1% sucrose, 2% sucrose, 3% sucrose, 1% fructose, 2% fructose, 3% fructose, and 1000 ppm IBA served as a positive control, while filtered water was a negative control. All treated cuttings were sown in the polybags containing soil mix and monitored daily for up to 45 days. The study found that black pepper cuttings treated with a 3% glucose solution exhibited significantly better survival, sprouting, and rooting, total number of roots, and total length of roots at day 45, but they were about the same when soaked in IBA at 1000 ppm. The present study demonstrates that cuttings that have been in transit for a long time require sugar and hormone treatment once they arrive at a certain location to restore their vitality and survival.</p>Fitri Ab Aziz ZakryNur Natasya Ilyanis IdrisMuhammad Iqbal Nul Hakim Mohd SaziliFranklin Ragai KundatNoorasmah SaupiSemsolbahri Bokhari

https://updatepublishing.com/journal/index.php/jp/article/view/8991
<p>Neonauclea species have been studied for their phytochemical and potential pharmacological uses. However, many of its species still remained unexplored. The Philippine endemic Neonauclea formicaria has been documented for its ethnobotanical use, but little has been reported on its phytochemical and pharmacological profile. Hence, this study evaluates the total phenolic (TPC) and flavonoid (TFC) contents and assesses its ethanolic leaf extracts’ antiglycation, antioxidant, and antibacterial activities. N. formicaria leaf extracts at 1000 ppm gave 63.02±5.82 mg GAE/g DW TPC and 31.25±4.24 mg QE/g DW TFC. The extract showed a concentration-dependent activity in inhibiting AGE formation for the antiglycation assay, with an IC50 value of 2823.5 ppm. In antioxidant assay, the extract exhibited the highest TEAC value of 419.5±14.3 mg TE/kg DW at 250 ppm. Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa were shown to be the most susceptible to the leaf extract (1000 ppm), with zones of inhibition at 16.56±5.65 mm and 14.06±2.65 mm, respectively. The results highlight that N. formicaria bears promising properties with pharmacological and nutraceutical applications.</p>Mirakel Zoe P. LayugJose Nathaniel F. DomagasEnrico C. SupanCameron D.

https://updatepublishing.com/journal/index.php/jp/article/view/9518
<p>Ethnomedicinal plants have played a vital role for human healthcare systems across the world. Ethnomedicinal research is necessary to investigate different biological resources for usage as remedies. Many traditional medicinal herbs have been utilized extensively by indigenous people of India to treat a variety of human and animal-related illnesses. The current ethnobotanical investigation was conducted in the Bodamalai Hills of the Eastern Ghats, Tamil Nadu, India. The study revealed that the Malayali tribes of Bodamalai Hills used 55 plants from 45 genera and 28 families to treat various diseases such as abdominal pain, arthritis, asthma, bone disorders, blood disorders, bronchitis, cancer, cardiovascular diseases, cholera, cold, cough, fever, constipation, cuts, wounds, diabetes, diarrhoea, dysentery, ear problems, elephantiasis, fertility problems, jaundice, malaria, nervous disorders, paralysis, piles, skin diseases, smallpox, stomach disorders, toothaches, tuberculosis, ulcers, and urinary disorders. The tribes still rely on medicinal plants. The research findings showed that the number of traditional medicinal healers is declining since younger tribes have begun to migrate to towns and cities and lack interest in and expertise in this type of medicine. Therefore, documentation is required in order to properly conserve the ethnomedicinal plants.</p>S. NigeshK. K. VijayakumarS. Mahendran

https://updatepublishing.com/journal/index.php/jp/article/view/9223
<p><em>Jasminum binhchauense </em>was recently described as a new species to science of which its specimen was found in Binh Chau-Phuoc Buu Nature Reserve, Vietnam. This study aims to characterize the DNA barcode and micro-morphological traits of <em>J. binhchauense </em>for the first time. As a result, the anatomical characteristics of the studied species were similar to those of <em>J. azoricum</em>. In addition, the <em>mat</em>K, <em>psa</em>B, and <em>psb</em>B regions of <em>J. binhchauense </em>were successfully amplified and sequenced and they were also deposited at the NCBI database with the accession numbers of PQ415075, PQ415076, and PQ415077, respectively. The pairwise alignment of the <em>mat</em>K, <em>psa</em>B, and <em>psb</em>B regions between <em>J. binhchauense </em>and <em>J. nervosum</em>, a morphologically resembled species, provided five, one, and two non-homologous locations, respectively.</p>Hong Thien VanMinh Thu Nguyen-ThiHong Thia LeThu Trang Le-ThiNga Nguyen-Phi

https://updatepublishing.com/journal/index.php/jp/article/view/9551
<p><em>In vitro </em>propagation of <em>Lycium chinense </em>is very important, which contributes to its effective multiplication as well as preservation. Accordingly, this study aimed to explore the influence of different carbon sources, auxins, silver nitrate (AgNO<sub>3</sub>), and putrescine on <em>in vitro </em>shoot regeneration and rooting from stem explants of <em>L. chinense</em>. Young shoots were generated on hormone-free Murashige and Skoog (MS) basal medium, and root and shoot experiments were then conducted to evaluate their effects. Among different carbon sources, sucrose (at 130 mM) and glucose significantly promoted root regeneration (highest number and length of roots). Of the auxins, the best root production occurred with indol-3-butyric acid (IBA) at 0.5 mg/L, and IAA and NAA generated root production at less than optimal levels with increased concentration. The co-application of IBA (0.5 mg/L) with AgNO<sub>3</sub> or putrescine enhanced shoot regeneration. The best rate of shoot production was observed with putrescine on both concentrations of AgNO<sub>3</sub> (5 mg/L on AgNO<sub>3</sub> and 100 mg/L on putrescine respectively) indicating the capability of these substances to enhance in vitro culture systems. These results will contribute to improving the efficiency of <em>L. chinense </em>regeneration via adventitious shoots through an easy setup of the culture conditions with an interest in propagation and other biotechnological applications.</p>June Bong KimNam Su KimJinsu LimKihyun KimMinhwan LeeMd Romij UddinRamaraj SathasivamChanung ParkSang Un Park

2025-04-152025-04-15252910.25081/jp.2025.v17.9551Phytochemical profile and antioxidant potential of leaf and bark extracts of Cassine glauca (Rottb.) Kuntze
https://updatepublishing.com/journal/index.php/jp/article/view/9278
<p>In the present study the phytochemical composition and antioxidant prospective of <em>Cassine glauca </em>leaf and bark extracts. Leaf and bark of <em>C. glauca </em>were extracted by methanol and chloroform through Soxhlet extraction. The extracts were analyzed for qualitative and quantitative phytochemical constituents, including phenolics, flavonoids, tannins, and other bioactive compounds. Antioxidant activity was determined through five different methods such as DPPH radical scavenging, reducing power, assay of molybdenum, hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) scavenging, and nitric oxide scavenging assays. Phytochemical analysis revealed that methanol extracts from both leaf and bark were more effective than chloroform, showing higher concentrations of phenolics, tannins and flavonoids. The leaf extract had a total phenol content of 47.458 mg GAE/g, tannins at 45.298 mg RE/g. and a flavonoid content of 160.106 mg TAE/g, and the bark extract showed lower but notable levels of these compounds. The leaf extract showed greater antioxidant activity when compared with bark extract in all experiments, includes DPPH radical scavenging activity, molybdenum assay, reducing power activity, nitric oxide scavenging activity and H<sub>2</sub>O<sub>2</sub> scavenging activities. Methanol extracts of <em>C. glauca </em>leaf and bark exhibited significant antioxidant properties, with the leaf extract showed greater efficacy. The present study highlights a prospective source of <em>C. glauca as </em>a potential resource of natural antioxidants and suggests additional exploration of its therapeutic benefits in oxidative stress-related disorders. The results emphasize the effectiveness of methanol as a solvent for extracting potential bioactive compounds from <em>C. glauca.</em></p>K. DhanasekaranKishore Kumar AshokK. PalanisamyP.
