چکیده
Trong nghiên cứu này, thành phần hóa học của cao chiết ethyl acetate từ thân và lá cây ba chẽ đã được cứu. Mẫu nguyên liệu khô được nghiền nhỏ, sau đó bằng phương pháp ngấm kiệt với methanol thu thô. Cao chiết thô phân tán trong nước và thực hiện quá trình lỏng- lỏng dung môi nhằm acetate. tách sắc ký trên cột silica gel Sephadex LH20. Kết quả lập bốn hợp chất sạch. Dựa vào dữ phổ 1H-NMR 13C-NMR kết hợp các tài tham khảo đã xác định cấu trúc của bốn chất hữu cơ là stigmasterol, methyl protocatechuate, syringate ferulate. Kết quả tích HPLC chỉ ra rằng các cực kém là chính chiết.

Since words are often considered as primitive units of language structures, the annotation of word segmentation forms the basis of these corpora. This is also an issue for the Vietnamese Treebank (VTB), which is the first and only publicly available...
متن کاملLearning Compositional Semantics for Open Domain Semantic Parsing
This paper introduces a new approach to learning compositional semantics for open domain semantic parsing. Our approach is called Dependency-based Semantic Composition using Graphs (DeSCoG) and deviates from existing approaches in several ways. First, we remove the need of the lambda calculus by using a graph-based variant of Discourse Representation Structures to represent semantic building bl...
