    Objectives: The main objective of the present study is to obtain callus and cell suspension culture from Balanitesa egyptiaca sterile plantlets grown in vitro and to compare growth and the biosynthetic potential of saponins, flavonoids and glycosides by callus and cell suspension culture Balanitisa egyptiaca. Methods: Callus was induced from the mother plants on MS culture media supplemented with  2.0 mg/l  BA + 2.0 mg/l  2,4-D with and without agar gelling. Total saponins, glycosides and flavonoids were estimated in both types of cultures over a period extending from 1 to 5 weeks to compare the productivity of such secondary metabolites in callus and cell suspension cultures. Results: The results obtained indicated that both calli and cell suspension cultures were able to synthesize the target active ingredients and that cell suspension culture was superior to the callus culture in the biosynthesis and accumulation processes. By the end of the incubation period, the amount of total saponins in cell suspension culture reached up 51.97±0.26 dry biomass compared to 35.02 ±0.06 mg/g in callus culture. The amount of total flavonoids in cell suspension culture reached up 10.88±0.24 dry biomass compared to 6.40±0.02 mg/g in callus culture and of total glycosides reached up 6.11±0.25 dry biomass compared to 5.06 ±0.05 mg/g in callus culture. Conclusions: The results obtained in this study may indicate the promising role that plant cell culture will play in the future in phytopharmaceutical industry.                          Peer Review History: Received 16 July 2020; Revised 12 August; Accepted 26 August, Available online 15 September 2020 Academic Editor: Dr. Iman Muhammad Higazy, National Research Center, Egypt, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.  Received file:                Reviewer's Comments: Average Peer review marks at initial stage: 6.0/10 Average Peer review marks at publication stage: 7.5/10 Reviewer(s) detail: Dr. Gehan Fawzy Abdel Raoof Kandeel, Researcher at pharmacognosy Department, National Research Centre, Egypt, [email protected] Ahmad Najib, Department of Pharmacognosy-Phytochemystry Universitas Muslim Indonesia-Indonesia, [email protected] Similar Articles: PHYTOCHEMICAL ANALYSIS AND ANTIMICROBIAL ACTIVITY OF COLOCASIA ESCULENTA (TARO) MEDICINAL PLANT LEAVES USED IN FOLK MEDICINE FOR TREATMENT OF WOUNDS AND BURNS IN HUFASH DISTRICT AL MAHWEET GOVERNORATE–YEMEN PHYTOCHEMICAL SCREENING AND THIN LAYER CHROMATOGRAPHIC OF PRUNUS DULCIS (ALMOND) MEDICINAL PLANT LEAVES USED IN FOLK MEDICINE FOR TREATMENT OF WOUNDS AND BURNS IN HUFASH DISTRICT AL MAHWEET GOVERNORATE–YEME

    Rosemary (Rosmarinus officinalis L.) is a popular herb in cooking, traditional healing, and aromatherapy. The essential oils of R. officinalis were obtained from plants growing in Victoria (Australia), Alabama (USA), Western Cape (South Africa), Kenya, Nepal, and Yemen. Chemical compositions of the rosemary oils were analyzed by gas chromatography-mass spectrometry as well as chiral gas chromatography. The oils were dominated by (+)-α-pinene (13.5%–37.7%), 1,8-cineole (16.1%–29.3%), (+)-verbenone (0.8%–16.9%), (−)-borneol (2.1%–6.9%), (−)-camphor (0.7%–7.0%), and racemic limonene (1.6%–4.4%). Hierarchical cluster analysis, based on the compositions of these essential oils in addition to 72 compositions reported in the literature, revealed at least five different chemotypes of rosemary oil. Antifungal, cytotoxicity, xanthine oxidase inhibitory, and tyrosinase inhibitory activity screenings were carried out, but showed only marginal activities
