Abstract
Different parts of lotus (Nelumbo nucifera Gaertn.) including the seeds, rhizomes, leaves, and flowers, are used for medicinal purposes with health promoting and illness preventing benefits. The presence of active chemicals such as alkaloids, phenolic acids, flavonoids, and terpenoids (particularly alkaloids) may account for this plant's pharmacological effects. In this review, we provide a comprehensive overview and summarize up-to-date research on the biosynthesis, pharmacokinetics, and bioactivity of lotus alkaloids as well as their safety. Moreover, the potential uses of lotus alkaloids in the food, pharmaceutical, and cosmetic sectors are explored. Current evidence shows that alkaloids, mainly consisting of aporphines, 1-benzylisoquinolines, and bisbenzylisoquinolines, are present in different parts of lotus. The bioavailability of these alkaloids is relatively low in vivo but can be enhanced by technological modification using nanoliposomes, liposomes, microcapsules, and emulsions. Available data highlights their therapeutic and preventive effects on obesity, diabetes, neurodegeneration, cancer, cardiovascular disease, etc. Additionally, industrial applications of lotus alkaloids include their use as food, medical, and cosmetic ingredients in tea, other beverages, and healthcare products; as lipid-lowering, anticancer, and antipsychotic drugs; and in facial masks, toothpastes, and shower gels. However, their clinical efficacy and safety remains unclear; hence, larger and longer human trials are needed to achieve their safe and effective use with minimal side effects.

[PMID: 33282196 PMCID: PMC7691928 DOI: 10.1177/2045894020969079] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Accepted: 10/06/2020] [Indexed: 01/06/2023] Open
Abstract
Pulmonary hypertension (PH) related to old anterior myocardial infarction (OAMI)
always accompanies a bad prognosis, and thus, we aimed to screen serum
biomarkers related to PH in OAMI patients. According to right ventricular
systolic pressure, we divided mice into sham, OAMI, and PH-OAMI groups and
evaluated body, heart and lung weight, heart function, pulmonary blood flow
velocity, cardiac fibrotic area, and pulmonary arteriole condition. Lung and
serum were under the proteomic analysis. Levels of three identified proteins
were measured. Compared with sham and OAMI mice, PH-OAMI mice showed heart
dysfunction, low pulmonary blood flow, high right ventricular systolic pressure,
heavy heart and lung weight, large cardiac fibrotic area, and pathological
pulmonary arteriole remodeling (P<0.05 or
P<0.01). Haptoglobin, annexin A5, and Ig mu chain C region
of lung and serum were changed significantly in PH-OAMI mice
(P<0.01). Then, we collected serum and clinical data,
measured three serum protein levels, and performed multivariate regression and
receiver operating characteristic curve in patients (normal, OAMI, and PH-OAMI
groups). Compared with normal and OAMI patients, serum levels of three proteins
in PH-OAMI patients were also altered notably (P<0.01).
These three proteins can predict PH in OAMI patients
(P<0.01). Receiver operating characteristic curve analysis
revealed haptoglobin (cut-off value: 78.295, sensitivity: 62.8%, specificity:
94.4%), annexin A5 (cut-off value: 151.925, sensitivity: 41.9%, specificity:
82.4%), and Ig mu chain C region (cut-off value: 168.885, sensitivity: 86.0%,
specificity: 79.6%) (P<0.01). Three circulating serum
proteins can be useful for the categorization of OAMI patients with and without
PH.
